    Full Text Available La dernière édition des Apports nutritionnels conseillés (ANC- éd. 2001 souligne la nécessité d’accroître la consommation d’acide alpha-linolénique (ALA. Celle-ci devrait au minimum doubler et représenter 0,8 % (par rapport à l’énergie totale contre 0,34 % actuellement. Or, l’étude Aquitaine [1] a montré que les lipides d’origine animale contribuaient à près de 75 % de l’apport alimentaire en ALA. Ainsi, parmi les stratégies envisageables pour accroître notre consommation d’ALA, sans changer fondamentalement les habitudes alimentaires des Français, on note un intérêt croissant pour augmenter la teneur en oméga 3 des produits animaux via l’alimentation de ces derniers. Quelques exemples de modification de la composition en acides gras des produits animaux sont exposés. Chez les espèces monogastriques (volaille, porc, le profil des lipides de carcasse est un bon reflet des lipides alimentaires. Ainsi, chez le porc, le niveau d’oméga 3 peut être augmenté d’un facteur 2 à 4, lorsque les animaux reçoivent dans leur alimentation de l’huile de colza, des graines de lin ou de la farine de poissons. En revanche, chez les animaux ruminants, le transfert des acides gras polyinsaturés alimentaires vers les tissus est faible en raison de l’hydrogénation qu’ils subissent dans le rumen. Certaines stratégies qui consistent à protéger ces acides gras de la biohydrogénation permettent néanmoins d’accroître le taux d’ALA dans les tissus et le lait. Ainsi, il apparaît possible d’augmenter la consommation d’oméga 3 de la population, via la consommation de produits issus d’animaux nourris avec des sources d’oméga 3. Cependant, au niveau de la production, ces changements doivent être maîtrisés \\; ils ne peuvent se faire sans un contrôle des qualités d’une part organoleptiques, en raison du degré élevé d’oxydabilité de ces acides gras, d’autre part de texture, en raison

    Due to the significant increase in overweight and obese people, action is needed to raise eating behaviour awareness. A significant main meal (lunch) is witnessing a growing trend in the catering (part of the out-of-home nutrition). The aim of this study is to determine whether the selection of lunch menus is affected through the display of nutritional information in the form of number of calories or a traffic light model. In this exploratory study, quantitative data were collected in a cross-sectional design. In addition to the established measurement instruments, socio-demographic and socio-economic information of the subjects based on the study were evaluated. The survey took place in 2008 in 2 passes (time t A/t B). The identical lunch menu of a catering company was applied twice respectively for 4 weeks. In the second run (t B) the lunch menu contained additional nutritional information (big 4 instructions) in the form of calories or a traffic light nutrition. The test of group differences was based on scientific statistical analysis in SPSS. The overall results for the illustration of kilocalories or traffic light do not have a unique significance in the direction of a low average number of calories at the time t B in comparison to the time t A. The food participants, on average, choose a lower calorie-containing menu, when a combination of traffic light and calories is given. The nutrition behaviour is accompanied by an oversupply of unhealthy foods. Lunch participants are sensitised for the selection of healthier lunch menus by a traffic light nutrition information or calories information. Nutrition labelling for lunch menus in the form of calories nutrition information or a coloured traffic light could trigger preventive effects. © Georg Thieme Verlag KG Stuttgart · New York.

    For the trace element selenium, in contrast to zinc, iron, copper, chromium, manganese and iodine, there is still no clear official recommendation with regard to routine substitution in artificial nutrition. An overview of the manifestations of selenium deficiency in humans during the period 1979-1995 shows that nutritive deficiencies are exclusively TPN-induced or the result of severe malnutrition. The pathology of TPN-induced selenium deficiency and the analytic assessment of selenium status are described. Patients undergoing long-term parenteral nutrition or suffering from an increased loss of intestinal secretions have to be characterized as being especially at risk for clinical selenium deficiency. The relationship of the serum selenium kinetics in pediatric and adult patients to the depletion of body compartments during the course of short-term and prolonged TPN is discussed. Because of the importance of the selenoproteins, the regularly occurring depletion during selenium-free TPN and the borderline supply of selenium in Germany the routine substitution of selenium in TPN is strongly recommended. The pharmaceutical industry should be encouraged to develop a trace element solution that includes selenium, so that the nutritive requirement of patients on TPN can be satisfied. Adequate intravenous dosage recommendations are based on maintenance of glutathione peroxidase homeostasis. The routine supplementation dosage may not meet the selenium requirements of intensive care patients under conditions of increased metabolic demands on their anti-oxidative system.

    The nutritional status of 15 patients suffering from unresectable carcinoma of the midthoracic esophagus was evaluated before and after palliative pulsion intubation. All patients showed evidence of protein-calorie malnutrition, prior to intubation. Oral alimentation using a formulated hospital ward diet with an elemental dietary supplement reversed the nutritional deficit. A mean daily positive nitrogen balance of seven grams was achieved three weeks following intubation. No episode of tube blockage was observed and the elemental diet supplement was well tolerated.

    1976-02-01

    From July 1971 to March 1975, elevan infants receiving total or partial parenteral alimentation at the University of Florida showed histologic evidence of intrahepatic cholestasis. The clinical records of these patients have been examined. These infants were critically ill and had protracted hospital courses with only two survivors. Liver biopsies demonstrated marked cholestasis with some fibrosis and thickening of the limiting membrane of the hepatocyte. In those patients in whom serial liver biopsies were obtained, hepatic histology returned toward normal, paralleling improvement in liver function studies, as intravenous alimentation was discontinued. Careful monitoring of the liver function tests is essential to detect this progressive abnormality as early as possible and discontinue intravenous alimentation. Follow-up as long as two and a half years in the two surviving patients has demonstrated no chronic dysfunction.

    Four children aged (11.7-13.5 yr) with protracted growth retardation related to Crohn's disease, received a 6-wk period of continuous elemental enteral alimentation with no other form of treatment. Despite drug therapy the yearly height and weight gain velocities of these children (1.7 +/- 0.3 cm and -0.8 +/- 1.4 kg, respectively) had been abnormal during the previous 2 yr. All patients experienced a complete remission of symptoms, improved nutritional status, and significant height (1.8 +/- 0.3 cm) and weight (3.8 +/- 0.5 kg) gains during the 67 wk of treatment. After cessation of elemental enteral alimentation, 3 of the 4 patients continued to grow, and over a period of 4.5 mo from the beginning of this form of nutritional therapy, they gained an average of 5.0 +/- 1.6 kg and 3.5 +/- 0.3 cm. The disease became active thereafter, and the 3 children resumed their previously abnormal growth patterns during the ensuing year. The 4th patient had surgery 2 mo after elemental enteral alimentation and experienced a subsequent second spurt of growth and pubertal changes. This study suggests that a relatively short course of elemental enteral alimentation leads to a temporary resumption of growth in children with severe growth failure and Crohn's disease. The possibility that repeated courses of elemental enteral alimentation might be beneficial needs to be explored.

    Growth arrest and delayed onset of puberty often complicate childhood onset Crohn's disease of the small bowel (granulomatous enteritis). Nutritional deficits arising from inadequate dietary intake, malabsorption, and increased caloric needs may contribute to growth retardation. To assess whether a sustained high caloric and nitrogen intake could reestablish growth, 4 children with extensive Crohn's disease of the small bowel were studied before and after parenteral alimentation which was instituted for symtomatic disease control. Weight gain, positive nitrogen balance, and improved nutritional status were achieved during parenteral alimentation in each patient. In 2 patients weight gain was sustained using oral nutritional supplements, and a substantial increase in linear skeletal growth continued in the ensuing months. One patient entered puberty within 4 months of parenteral alimentation and another had the onset of menarche and the development of secondary sex characteristics 4 months after parenteral alimentation and resection of diseased bowel. Growth may be reestablished in some growth-arrested children if intake is sufficient to establish a sustained positive caloric and nitrogen balance. Nutritional requirements imposed by the demands of growth and active disease and often compounded by the catabolic effects of corticosteroids may be excessive; growth may occur only if these needs are met orally and/or parenterally.

    We provided partial peritoneal alimentation to a 1.69-kg 11-month-old premature infant who had no available central venous access, depleted peripheral venous access, and gastrointestinal dysfunction. A cuffed silastic catheter was surgically inserted into the suprahepatic space. An alimentation solution was continuously infused into the peritoneum for 28 days to supplement peripheral venous and nasogastric alimentation and contributed 42 +/- 15% of total calories daily. Weight gain was achieved, but complications included hypoglycemia, hypophosphatemia, intravascular dehydration, catheter site leakage, ascites, and hydrocele. At autopsy 11 months later, lipid accumulation was present in the upper peritoneum and the hilar regions of the lungs secondary to preexisting lymphatic obstruction. Partial peritoneal alimentation may be feasible when other access routes are inadequate, but lymphatic obstruction is a contraindication to the peritoneal administration of lipid emulsions.

    Recent in vitro observations suggest that the intestine, in addition to the liver, may be an important organ of first-pass drug metabolism. While a variety of changes in intestinal morphology and function in response to continuous parenteral and enteral nutrition have been documented, the effect of different routes of alimentation on intestinal drug metabolism has not been previously investigated. Objectives of this study were to assess the contribution of intestinal pentobarbital metabolism to overall in vivo pentobarbital pharmacokinetics in the rat and to determine if differences in pentobarbital pharmacokinetics were seen between parenterally and enterally nourished animals. After 7 days of continuous infusion of amino acid-glucose mixture via a gastric or jugular vein catheter, pharmacokinetic parameters were determined after 40 mg/kg of pentobarbital was given orally or into the portal or femoral vein. Reduced systemic availability of pentobarbital after oral administration as compared to portal vein injection was seen in both alimentation groups indicating that significant intestinal metabolism of pentobarbital occurred in vivo. Total area under the pentobarbital plasma concentration-time curve was significantly greater in parenterally nourished animals as compared with enterally alimented animals after oral, portal vein and systemic vein drug administration. Differences in pentobarbital, pharmacokinetics between the two alimentation groups appeared to be primarly due to effects on hepatic pentobarbital metabolism. While the mechanism producing these changes has not been defined, differences in gut hormones release and/or pancreatic secretion in response to the two routes of alimentation may be contributory. The widespread use of enteral and parenteral alimentation in clinical medicine suggests that studies to determine if nutrition route of administration similarly influences drug metabolism in humans may be indicated.

    Hypophosphatemia is uncommon in cats, but it has been reported in association with diabetes mellitus and hepatic lipidosis, where it can cause hemolysis, rhabdomyopathy, depression, seizures, and coma. The purpose of this article is to describe 9 cats that developed low serum phosphorus concentrations (alimentation. Serum biochemical analyses from more than 6,000 cats were reviewed. The medical records of all cats with hypophosphatemia were examined for history of enteral alimentation; diabetic cats were excluded from the study. Nine cats, ranging in age from 3 to 17 years, were identified. All cats had normal serum phosphorus concentrations before tube feeding began. Onset of hypophosphatemia occurred 12 to 72 hours after initiation of enteral alimentation, and the nadir for phosphorus concentrations ranged from 0.4 to 2.4 mg/dL. Hemolysis occurred in 6 of the 9 cats. Hypophosphatemia secondary to enteral alimentation is an uncommon clinical finding in cats. Cats with high alanine aminotransferase activity, hyperbilirubinemia, and weight loss should be closely monitored for hypophosphatemia during the first 72 hours of enteral alimentation.

    Malnourished patients who cannot maintain an adequate oral intake but have normal intestinal absorption and motility are candidates for enteric alimentation. When impaired gastric peristalsis or an increased risk for aspiration makes gastrostomy feeding unsafe, direct jejunal infusion is the preferred route of alimentation. Angiographic techniques were used to convert previously placed, simple gastrostomies to combined gastrostomy-jejunostomies in 14 patients. In 17 additional patients, a combined gastrostomy-jejunal tube was placed under local anesthesia; angiographic techniques assisted in the placement of 11 of these tubes.

    The history of percutaneous endoscopic gastrostomy (PEG) is relatively short. In 1980, a report entitled "Gastrostomy without laparotomy: A percutaneous endoscopic technique" by Ponsky and Gaudere was first published in the Journal of Pediatric Surgery. Thereafter, PEG soon saw widespread use in Western countries because of its clinical efficacy and economy. It has been performed in about 170,000 cases annually in the US. In contrast, its spread in Japan has been extremely slow: only about 10,000 cases have undergone this procedure annually, and this number accounted for less than 5% of patients receiving enteral alimentation. The reason why PEG has not spread may be the medical insurance system in Japan and the local distaste for operation scarring. However, in consideration of the unprecedented ageing of society that is surely coming in the near future, the role of PEG in Japan must be reexamined. In this report, we presented the methodology of enteral alimentation at home by means of PEG, giving special consideration to: (1) "What points are improved by using enteral alimentation at home by means of PEG in various diseases; (2) dysphagia due to cerebral angiopathy; (3) terminal cancer; (4) otolaryngological diseases; and (5) Crohn disease. We also discussed "Why PEG is important now?" in performing enteral alimentation at home.

    1987-10-01

    Changes in ovine visceral organ mass and small intestinal mucosa morphology and metabolism due to short-term and prolonged modifications in level of alimentation were studied. Thirty-six lambs were fed for 21 d at either 100 or 50% ad libitum levels of intake. For the next 5 d, lambs either remained on the same intake levels or were switched from 100 or 50% or from 50 to 100% ad libitum intake levels and were subsequently slaughtered. Levels of alimentation the last 5 d before slaughter had a significant effect on weights of the large intestine, small intestine, stomach complex and liver, while only the weight of the liver was affected by 21-d adaptation period. Weights of the heart, lungs, carcass and visceral fat were not affected by level of alimentation. Villus height and mucosal mass at a constant intestinal tissue weight were modified by level of alimentation 5 d before slaughter but static to the previous 21-d nutritional plane. Activity of Na+, K+ ATPase of jejunal mucosa was not influenced by level of alimentation 5 d before slaughter, but was influenced by 21-d adapted level of alimentation. Results from this study are interpreted to indicate that weights of the liver and alimentary tract and small intestinal mucosa development are highly sensitive to changes in level of alimentation.

    Glutamine should be reclassified as a conditionally essential amino acid in the catabolic state because the body's glutamine expenditures exceed synthesis and low glutamine levels in plasma are associated with poor clinical outcome. After severe stress, several amino acids are mobilized from muscle tissue to supply energy and substrate to the host. Glutamine is one of the most important amino acids that provide this function. Glutamine acts as the preferred respiratory fuel for lymphocytes, hepatocytes and intestinal mucosal cells and is metabolized in the gut to citrulline, ammonium and other amino acids. Low concentrations of glutamine in plasma reflect reduced stores in muscle and this reduced availability of glutamine in the catabolic state seems to correlate with increased morbidity and mortality. Adding glutamine to the nutrition of clinical patients, enterally or parenterally, may reduce morbidity. Several excellent clinical trials have been performed to prove efficacy and feasibility of the use of glutamine supplementation in parenteral and enteral nutrition. The increased intake of glutamine has resulted in lower septic morbidity in certain critically ill patient populations. This review will focus on the efficacy and the importance of glutamine supplementation in diverse catabolic states.

    Total parenteral nutrition with lipids is a well-accepted modality of metabolic support in seriously ill trauma patients. Intolerance to lipid administration is unusual when dosage limits are not exceeded, and few hematologic disturbances have been recorded with modern fat emulsions. In the course of intravenous alimentation of six adults admitted for traumatic lesions, eosinophilia with or without leukocytopenia was noticed after periods of four days to five weeks. Principal clinical events and hematologic derangements were documented in this population. Sepsis was not always present in the patients by the time of the complication, and in those that did require antibiotics and other drugs, the prescription remained unchanged along the episode. Discontinuation of the nutritional regimen with lipids was followed by normalization of the hematologic profile, suggesting that an acute or sub-acute allergic reaction was responsible. The appearance of skin rash in two occasions reinforces this hypothesis, and the possibility of hemophagocytosis merits consideration in two of the cases who displayed reversible acute leukocytopenia. It is concluded that blood cell aberrations are possible during intravenous feeding with lipids in trauma subjects, but tend to respond to suppression of the lipid-containing nutritional prescription.

    The plasma concentrations of the trace metals zinc and copper were studied prospectively in 13 patients with gastrointestinal diseases treated with parenteral alimentation (TPA) for periods of from 8 days to 7 1/2 weeks. Plasma copper levels fell rapidly and consistently in all patients, with an overall rate of - 11 mug per 100 ml per week. Zinc concentrations declined in 10 of 13 patients at a more gradual rate. Analysis of the standard parenteral alimentation fluids revealed zinc content equivalent to 50% of the daily requirement and a negligible content of copper. From combined analysis of plasma zinc, hair zinc, and taste acuity, there is evidence that increased utilization or redistribution within the body may effect plasma concentrations in some patients. Neither an increase in urinary excretion nor a primary decrease in plasma binding proteins appeared to be a major factor in lowering plasma trace metal concentrations. These findings indicate that a marked decrease in plasma copper is regular and a decline in plasma zinc is common during TPA using fluids unsupplemented with trace metals. Supplementation of parenteral alimentation fluids with the trace metals zinc and copper is recommended.

Tous les aliments ayant au minimum une fonction « santé » qui est l’apport énergétique, ces nouveaux aliments doivent donc se démarquer en apportant un bénéfice santé supérieur à l’alimentation classique. Serge Hercberg1 les caractérise par une « valeur santé ajoutée », qui peut être soit une fonction cible améliorée, soit la réduction du risque d’une pathologie. Ainsi, un produit apportant des phytostérols à une dose active pourra contribuer à « diminuer significativement le LDL-cholestérol » et un produit enrichi en AGPI oméga 3 peut revendiquer un apport en nutriments qui « contribuent à la réduction des risques cardiovasculaires ». Il nous paraît important de limiter la notion d’aliment fonctionnel à un produit industriel élaboré pour lequel soit la technologie, soit la formulation, soit les deux ont été volontairement adaptées ou optimisées pour obtenir une fonctionnalité ciblée sur notre métabolisme. On constate en effet un amalgame et une vulgarisation du message « santé » pour des produits qui sont

    Ten pediatric patients, aged 8.5-19 years, with active symptomatic Crohn's disease, received a three-week period of continuous elemental enteral alimentation with no other form of treatment. All patients in this study were selected according to the following criteria, which were applied consecutively: (1) newly diagnosed patients with no previous treatment for Crohn's disease, (2) disease activity index over 200, and (3) no complication requiring surgery. All patients experienced a clinical remission and improved their immunologic and nutritional status during the elemental enteral alimentation. The mean disease activity index for the whole group was 307.0 +/- 23.6 (range: 203 to 413) before and 69.2 +/- 11.4 (range: 15 to 114) after the feeding period. Significant increases in body weight, triceps skinfold, mid-arm circumference, serum transferrin and mean percentage of T lymphocytes were also observed. Following cessation of enteral alimentation, a small declining dose of prednisone was used during a one-year follow-up period. Eight of the ten patients were still in clinical remission three months after the feeding period and their nutritional status had continued to improve during that period of time.

    The incidence of upper gastrointestinal (GI) bleeding in mechanically ventilated ICU patients receiving enteral alimentation was reviewed and compared to bleeding occurring in ventilated patients receiving prophylactic antacids or cimetidine. Of 250 patients admitted to our ICU during a 1-yr time period, 43 ventilated patients were studied. Patients in each group were comparable with respect to age, respiratory diagnosis, number of GI hemorrhage risk factors, and number of ventilator, ICU, and hospital days. Twenty-one patients had evidence of GI bleeding. Fourteen of 20 patients receiving antacids and 7 of 9 patients receiving cimetidine had evidence of GI bleeding. No bleeding occurred in 14 patients receiving enteral alimentation. Complications of enteral alimentation were few and none required discontinuation of enteral alimentation. Our preliminary data suggest the role of enteral alimentation in critically ill patients may include not only protection against malnutrition but also protection against GI bleeding.

    Femoral vein catheterization is an alternative method of obtaining central venous access. Placement of femoral venous catheters (FVCs) is possible in the majority of patients, suitable for most indications, and associated with a low complication rate during insertion. We wished to determine the incidence of infections or other complications resulting when parenteral nutrition was delivered through FVCs. Fifty-two patients were followed from a hospital-wide population including patients in the critical care units. Triple-lumen catheters were placed by using the sterile Seldinger technique, and sites were examined daily for inflammation. Bacteriologic surveillance was accomplished by submitting the catheter tip for semiquantitative cultures. If catheter line sepsis was suspected, blood samples for cultures were drawn through the catheter and peripherally. The rate of occurrence of colonized catheters was 9.6% (five of 52), and catheter sepsis was found in one case (1.9%). Other than inflammation at six (11.5%) of 52 catheter sites, noninfectious complications of FVCs were not found. On the basis of these findings, we consider FVC-delivered parenteral alimentation a safe and effective alternative to other forms of central venous access.

    Standard care for patients with renal failure while in an intensive care unit involves traditional hemodialysis or peritoneal dialysis and protein restriction. We present a case of a patient with renal failure supported with continuous arteriovenous hemofiltration with dialysis (CAVH-D) who was given full protein alimentation. Total daily urea clearance was measured from the CAVH-D output. Protein load was 196 +/- 34 g/day while receiving total parenteral nutrition and 164 +/- 30 g/day while receiving enteral alimentation. Serum blood urea nitrogen was controlled between 40 and 75 mg/dL, except during septic episodes. Nitrogen balance was estimated based upon known alimentation protein load and measurable and estimated nitrogenous losses. The patient was potentially in nitrogen equilibrium during most of the dialysis period. The cumulative nitrogen balance was positive by 5.2 g after 67 days of dialysis. Volume of alimentation was 3.49 +/- 0.7 liters/day. With CAVH-D, the renal failure patient can receive full alimentation without volume or protein load limitations. Furthermore, nitrogen balances can be estimated easily while the patient is on CAVH-D.

    We have evaluated the methodological quality of the Rémic (microbiology guidelines - bacteriology and mycology) of the Société française de microbiologie (edition2007), using to AGREE criteria, which are consensual at an international level, in particular at the the World Health Organisation (WHO) and at the European Union. The methodological quality of the Rémic appears to be sub-optimal. These shortcomings in quality are mainly observed in AGREE domain n° 5 (applicability), in AGREE item n° 5 (patients' opinions were not considered), and in AGREE item n° 23 (conflicts of interest were not declared). The users of the Rémic must be aware of these few methodological shortcomings in order for them to be careful before they put its recommendation in practice. In conclusion, we advise the editors of the Rémic to insert at least a methodological chapter in their next edition.

    Different food items are made responsible for irritable bowel syndrome (IBS) symptoms, but the physiopathology of IBS remains unclear. During a meeting in Nice, France, experts of the European Working Team of the IBiS Club discussed selected data regarding the relationships between alimentation, food items (including fibers) and IBS symptoms. Food allergy remains a difficult diagnosis, but medical and general history, presence of general symptoms such as skin rash, and hypersensitivity tests may help in achieving a positive diagnosis. On the other hand, food intolerance is more confusing because of the subjectivity of the relationship between ingestion of certain foods and the appearance of clinical symptoms. Different food items which are commonly implicated in adverse reactions mimicking IBS were found to be stimulants for the gut, suggesting that patients with predominant diarrhea IBS have to be carefully questioned about consumption of different kinds of food (i.e., coffee, alcohol, chewing gum, soft drinks) and not only on lactose ingestion. Gas production is discussed on the basis of retention of intestinal gas as well as on malabsorption of fermentable substrates. The role of a large amount of this kind of substrate reaching the colon is suggested as a potential mechanism of IBS-type symptoms in overeating patients. Regarding the role of fiber in IBS, the expert group concluded that fibers are not inert substances and that they could trigger pain or bloating in some IBS patients. Despite numerous reviews on this subject, it is very difficult to give general dietary advice to IBS patients, but dieteticians may have a positive role in managing such patients. Copyright 2003 S.

    Liver biopsy was performed to exclude anatomic obstruction of the biliary tract in five prematurely born infants who had developed conjugated hyperbilirubinemia during intravenous alimentation with a protein hydrolysate. Each was being treated after having undergone a segmental intestinal resection for necrotizing enterocolitis. Bacterial and viral infections, metabolic disorders, and isoimmune hemolytic disease were excluded as possible causes of jaundice. Light microscopic and ultrastructural analysis disclosed cholestasis and hepatocellular injury without significant inflammatory reaction. Jaundice abated following permanent discontinuation of parenteral alimentation. The jaundice and cholestasis are interpreted to be hepatotoxic effects because of (1) their temporal relationship to the treatment and (2) the presence of hepatocellular damage.

    1983-04-01

    Intrahepatic and intracerebral metabolic responses to neonatal fasting or enteric carbohydrate alimentation were investigated among newborn dogs. Pups were either fasted or given an intravenous glucose infusion (alimented) before an enteric feeding of physiologic quantities of either glucose or galactose. These pups were also compared to another group which was completely starved throughout the study period. Gastrointestinal carbohydrate feeding resulted in enhanced hepatic glycogen content among pups after a prior state of fasting. Though there were no differences of glycogen content between glucose or galactose feeding in this previously fasted group, combined intravenous glucose and enteric galactose administration produced the greatest effect on hepatic glycogen synthesis. Intrahepatic fructose 1, 6-diphosphate and phosphoenolpyruvate levels were increased among previously fasted pups fed enteric monosaccharides compared to completely starved control pups, whereas intrahepatic phosphoenolpyruvate and pyruvate levels were elevated after combined intravenous and enteric carbohydrate administration. Of greater interest was the observation that hepatic levels of ATP were significantly elevated among all groups given exogenous carbohydrates compared to the completely starved control group. In contrast to the augmented hepatic glycogen and ATP levels, there were no alterations of cerebral glycogen or ATP after alimentation. Nevertheless, cerebral pyruvate and/or phosphoenolpyruvate concentrations were elevated after enteric or combined intravenous and enteric alimentation compared to the totally starved control pups.

    This is a report on various post-gastrectomy reconstructive procedures, proceeding from personal experience had with 14 patients undergoing gastrectomy for carcinoma of the stomach and five patients with operations of esophagus and stomach for various pathological conditions. An assessment is done of the reconstructive methods used on the ground of objective indicators. All patients are subjected to enteral alimentation through nutritive jejunostomy. In the pre- and postoperatived periods, the trophic state of patients is evaluated on basis of biochemical, anthropometric and immunologic study data. Postoperatively, in those with small-intestinal reservoir a lower degree negative symptomatology is established, along with life style improvement. Post-gastrectomy patients presenting I-II (UICC) stage of the oncological disease are indicated for small-intestinal reservoir formation. In the overall therapeutic approach to post-gastrectomy patients adequate clinical therapeutic feeding proves absolutely indispensable.

  9. Re-alimentation in harbor seal pups: effects on the somatotropic axis and growth rate.

    2010-01-15

    The metabolic hormones, growth hormone (GH) and insulin-like growth factor (IGF)-I, together with IGF binding proteins (IGFBP), have been well studied in domestic species and are the primary components of the somatotropic axis. This hormone axis is responsive to nutrient intake, associated with growth rate, and accretion of protein and adipose. However, this relationship has not been evaluated in species that rely heavily on adipose stores for survival, such as pinnipeds. The primary objectives of this research were to investigate the response of the somatotropic axis to reduced nutrient intake and re-alimentation in rehabilitated harbor seal pups, and to assess if these hormones are related to nutritional status and growth rate in harbor seals. Stranded harbor seal pups (n=24) arrived at the rehabilitation facility very thin after fasting for several days (nutritional nadir). Throughout rehabilitation nutrient intake increased and pups gained mass and body condition. Concentrations of GH and IGFBP-2 decreased with re-alimentation, while IGF-I and IGFBP-3 concentrations increased. Overall, GH and IGFBP-2 were negatively associated and IGF-I and IGFBP-3 were positively associated with growth rate and increased body condition of harbor sea pups. Further, the magnitude of the growth response was related to the magnitude in response of the somatotropic axis to varied levels of intake. These data suggest that multiple components of the somatotropic axis may be used to assess the energy status of individuals and may also provide information on the level of feed intake that is predictive of growth rate.

    In 50 patients aged between 3 and 84 years treated in a multidisciplinary Intensive Care Unit and receiving parenteral alimentation, deficiency in certain trace elements or electrolytes (Cu++, Zn++, Mn++, Co++, PO-4, Mg++) was prevented or treated by the administration of a glucose solution (MB 147 G) enriched in trace elements. The aim of the present study was to demonstrate, on the basis of assay of serum levels of the trace elements involved, with the exception of Mn and Co, the effectiveness of treatment. Reference values were determined on the one hand in healthy individuals for normal figures and secondly on subjects included in the study, already on parenteral alimentation for several days, before treatment with MB 147 G, in order to demonstrate the existence of a deficiency (patient control values). In the case of PO--4, however, the patient control values concerned at one and the same time subjects in the study before treatment with MB 147 G and other patients receiving parenteral alimentation who were not part of the trial. MB 147 G solution was presented in units of 500 ml associated with glucose of varying concentrations (15 p. 100, 30 p. 100, 50 p. 100). The average daily amount administered, over a period of 236 days, was 3 unites per 24 hours, corresponding to an intake of copper of 3.78 mg, 3.90 mg of zinc, 0.20 mg of manganese, 0.24 mg of cobalt, 363 mg of magnesium, 240 mg of calcium and 15 mEz of phosphates. The results show that levels of copper, zinc, magnesium and phosphates were low during parenteral alimentation. The administration of MB 147 G resulted in a significant increase in these values, without there being any evidence of accumulation.

    We have previously shown that substantial losses of fat-soluble (FS) vitamin A from parenteral alimentation solution occur due to adsorption in the intravenous tubing and photodegradation in the bottle. This study assessed the delivery of other vitamins, viz, FS vitamin E and water-soluble (WS) vitamin C, from parenteral alimentation solution. The solution containing 2.0 ml/L of an aqueous multivitamin infusion was infused at a constant rate of 10 ml/h using a standard intravenous administration set. Multiple aliquots of the solution from the bottle and the effluent obtained sequentially in a 24-h period were analyzed for concentrations of vitamins E and C. Both vitamins remained relatively stable in the bottle. A significant amount (12%) of vitamin E was lost in the intravenous tubing. No losses of vitamin C were incurred in the intravenous tubing. The data suggest that delivery of FS vitamin E from parenteral alimentation solutions is less than optimum because of adsorptive losses. Similar losses are not encountered with WS vitamin C.

    1986-11-01

    A technique for duodenal alimentation (needle catheter duodenostomy) of birds was developed, using the domestic pigeon (Columba livia) as the experimental model. A needle catheter was inserted into the descending duodenum of 5 pigeons and was secured to the body wall and dorsum of each bird. A liquid diet was administered daily (in equal amounts of 0, 4, 8, 12, and 16 hours) for 14 days without adverse effects. On day 15, the catheters were removed, and the birds immediately resumed normal consumption of a pigeon ration and water diet. Although 4 of the 5 birds had minor weight loss, dietary alterations probably could be used on an individual basis to alleviate this problem. After oral alimentation was resumed, the 5 birds exceeded their initial body weight within 7 days. Four weeks after catheter removal, positive-contrast radiographic evaluations indicated that the duodenum of each pigeon appeared normal. Needle catheter duodenostomy was a viable method of alimentation in the domestic pigeon. This technique should be applicable for other avian species requiring bypass of the upper gastrointestinal tract proximal to the region of catheter insertion in the duodenum.

    Improvement in body condition and carcass traits through nutritional intervention was studied in cull ewes. Sixty-eight adult non-productive Malpura ewes (average body weight 26.7 ± 0.33 kg) were randomly divided into four equal groups: G0 maintained on free grazing for 8 h on protected natural rangeland with ad libitum guar (Cyamopsis tetragonoloba) straw (GS) after grazing; G1, G2 and G3 fed with supplemental concentrate at the rate of 250 g, 2.5% of live weight (LW) and ad libitum, respectively. The experiment was continued for 90 days and daily feed intake, weekly LW and body condition score (BCS) were recorded. Intake and digestibility of nutrients were assessed by indicator method. Rumen fermentation attributes and blood biochemical profile were studied to assess the dietary effects and animals were slaughtered at the end of experiment for evaluation of carcass characteristics. Higher dry matter (DM) intake and improvement in plane of nutrition was observed in G2 and G3 with a higher LW gain (LWG) and improvement in BCS than in G0. The digestibility of DM, organic matter, CP, ADF and cellulose was higher (P alimentation of cull ewes with challenged feeding of concentrate at 2.5% of LW on a basal roughage diet for a period of 3 months may have promise for better economic return to the farmers with possibly meeting quality mutton for human consumption.

The protein substances that the meat contains have a high biological value, due to the fact that they have all the necessary amino acids needed to maintain a healthy azote balance within the body. The production of meat is quite a complex operation, that is based not only on the market needs (which is mostly based on price and income, but also a multitude of social and economic influences.

    Enteral alimentation, given via nasogastric or gastrostomy tubes, is a well established practice to provide nutrition for patients with significant neurological injury. The frequency with which enteral feeding bags and tubes require change and potential adverse effects associated with bacterial contamination of tube feeds remain controversial. The authors studied different times between enteral feeding bag and tube changes, and the effect on adverse clinical outcomes in residents of a long term care facility. In the first study, residents were randomized to 24 h (n = 2), 48 h (n = 3) or 72 h (n = 6) tube feeding and bag changes with clinical status monitored in a standardized fashion for six months. In the second study, patients were randomized to 24 h (n = 6) or 72 h (n = 6) changes. Patient-days of follow-up were 382, 574 and 1000 for the three arms of the first study period and 556 and 496 for the two arms of the second study. No differences in potential clinical adverse events--including fever, gastrointestinal symptoms or pneumonia--were observed with different durations of tubing change. This study suggests it is appropriate to change alimentation tube and feeding bags every 72 h (rather than every 24 h). The less frequent changes will decrease supply costs and free nursing time for other activities.

    1996-09-01

    The present study tested the influence of protein undernutrition and re-alimentation on mammary gland size and secretory cell activity in lactating rats. During gestation, female Sprague-Dawley rats were offered a high-protein diet (215 g crude protein (N x 6.25; CP)/kg DM; H); litters were standardized to twelve pups at parturition. During lactation, two diets were offered ad libitum, diet H and a low-protein diet (90 g CP/kg DM; L). Lactational dietary treatments were the supply ad libitum of either diet H (HHH) or diet L (LLL) for the first 12 d of lactation, or diet L transferring to diet H on either day 6 (LHH) or 9 (LLH) of lactation. On days 1, 6, 9 and 12 of lactation, rats from each group (n > or = 6) were used to estimate mammary dry mass, fat, protein, DNA and RNA; the activities of lactose synthetase (EC 2.4.1.22) enzyme and Na+,K(+)-ATPase (EC 3.6.1.37) were also measured. Rats offered a diet considered protein sufficient (H) from day 1 of lactation showed a decrease in mammary dry mass and fat but an increase in DNA, RNA and protein on day 6, after which there was no further change, except for mammary protein which continued to increase. However, rats offered diet L showed a steady loss in mammary mass and fat throughout the 12 d lactation period and no change in mammary DNA, RNA or protein. Rats previously protein restricted for either the first 6 or 9 d of lactation had their mammary dry mass and mammary fat loss halted and showed a rapid increase in mammary DNA, RNA and protein on re-alimentation. Lactose production in group HHH, as measured by lactose synthetase activity, was similar on days 1 and 6 of lactation, after which a significant increase was seen. Protein-restricted rats showed no change in lactose synthetase activity during the 12 d experimental period. Changing from diet L to diet H led to a significant increase in lactose synthetase activity to levels comparable with those offered diet H from day 1. These results show that rats

    Full Text Available Daniel, Lucien, Gérard et Jean-Baptiste habitent une cabane dans une ruelle d'une grande ville. Leur alimentation est issue principalement de dons, de restes ou de déchets. Le terrain mené auprès d'eux permet de mettre en évidence comment ces denrées doivent être revalorisées pour pouvoir être consommées. Entrent en ligne de compte les conditions de leur obtention, l'acte culinaire et la création de déchets qui s'en suit. L'analyse montre donc que loin de se réduire à sa dimension nutritive, l'alimentation dans ces conditions de précarité organise la vie sociale des habitants de cette cabane : c'est par elle que passe la création de relations cordiales avec le voisinage, et la possibilité de devenir aidant/donateur à son tour auprès de personnes encore plus démunies.Daniel, Lucien, Gérard and Jean-Baptiste live in a shack, in a city back-alley. They get their food mainly from donations, left-overs or waste. The fieldwork performed in their company sheds light on the fact that new values must be conferred to such foods in order to become edible. What matters is how the food was obtained, the cooking process, and the subsequent production of waste. The analysis shows that feeding in such precarious conditions, far from being reduced to its nutritive dimension, organizes the social life of this shack's residents: food is what makes friendly relations possible with neighbours and gives the opportunity to become helper/ donator in turn towards even more destitute persons

    Full Text Available The type of alimentation and the food quality of individuals has undergone remarkable changes along with the progress of the human species. This study contains an historical overview regarding human nutrition from the primitive forms until the paradoxes of contemporary alimentation. Nutritional education aims to inform and to train a person about food choices, dosage and cooking, how to identify authentic food and to understand the value of nutrition. Children need a balanced diet in order to grow and to become healthy adults. The importance of nutritional education in school is discussed taking into account the need of creating healthy eating habits which should be followed through the whole life, but also the lack of physical activity to children.

  10. Minimizing systemic infection during complete parenteral alimentation of small infants

    Science.gov (United States)

    Nelson, R.

    1974-01-01

    A regimen of parenteral alimentation for infants was designed to eliminate as many factors responsible for infection as possible. The most important features of the feeding regimen were as follows. (1) Infants were fed via indwelling silastic catheters inserted into the superior vena cava or the right atrium by a cutdown operation. (2) The parenteral feeding was fat free to simplify the administration system. Y connectors and 2- or 3-way taps were avoided. (3) Extreme care was taken of junctions within the infusion system. Only certain members of the hospital staff were allowed to break such junctions, e.g. during the changing of packs of solution or of the giving sets. These junctions were sprayed with antibacterial aerosols. (4) The hypertonic solutions of nutrients were prepared in plastic packs, which do not require ventilation. The infusion system was therefore not contaminated by the entry of unsterile outside air. (5) The infused solutions were passed through 0·22 μm millipore filters before entering the patient's blood stream. There was an infection rate of 9% which was less than the 25 to 45% infection rate previously reported during parenteral feeding through indwelling venous catheters, and is also less than that associated with ventriculoatrial shunts for hydrocephalus. There was no case of systemic candidiasis, which is the most frequent and most serious infection associated with parenteral feeding. PMID:4206445

    Use of high-flow oxygen via nasal cannula (HFO2-NC) is increasingly common in intensive care unit (ICU) settings. Despite the critical interface between respiration and swallowing, and the high acuity of patients in ICUs, the impact of HFO2-NC on feeding and swallowing is unknown. The present prospective, single-center, cohort study investigated the impact of HFO2-NC use on oral alimentation in neonatal and adult ICU patients. Oral alimentation status was evaluated in 100 consecutive ICU inpatients (50 neonatal and 50 adult) requiring HFO2-NC. Participant characteristics, respiratory support, successful initiation of oral feeding in neonates, and successful resumption of oral feeding in adults were recorded. Seventeen of 50 (34 %) neonates requiring HFO2-NC were deemed developmentally and medically appropriate by the neonatologist and nursing to begin oral alimentation. All 17 (100 %) were successful with initiation of oral feedings. Thirty-three of 50 (66 %) continued nil per os due to prematurity or medical conditions precluding oral alimentation at time of data collection. Thirty-nine of 50 (78 %) adults requiring HFO2-NC were deemed medically appropriate by the intensivist and nursing to resume oral alimentation (n = 34) or with a functional swallow without aspiration on FEES (n = 5). All 39 (100 %) resumed oral alimentation successfully. Eleven of 50 (22 %) continued nil per os due to severe respiratory issues precluding both swallow testing and oral alimentation at time of data collection. All developmentally and medically appropriate neonatal and adult patients requiring HFO2-NC were successful with either the introduction or resumption of oral alimentation. Patients requiring HFO2-NC who are identified as having feeding or swallowing issues should be referred for swallowing evaluations using the same criteria as patients who do not require HFO2-NC, as it is not the use of HFO2-NC but rather patient-specific determinants of feeding and swallowing

    1985-04-01

    The postoperative growth rates achieved in eight early pubertal adolescent males with Crohn's disease undergoing surgery for obstructive complications is reported as a function of the use of 1 month's preoperative central venous alimentation. All patients had ileal strictures with ileocolitis, bone ages less than 13, Tanner stages 1 or 2, and growth velocities below the 3rd percentile for age. During a 3-year follow-up, those receiving preoperative venous alimentation demonstrated greater oral caloric intake (significant for 1 year) and greater postoperative growth velocity (significant for 2 years) in comparison to those patients who did not receive preoperative venous alimentation. There was no significant difference between the two groups of patients in postoperative weight gain, sexual development, and 3-year disease control.

    The problem of protein calorie malnutrition following major gastrointestinal surgery can be treated with central venous or enteric alimentation, with the latter being preferred. The authors describe a simple technique for the conversion of biliary stents placed after pancreaticoduodenal surgery into jejunal feeding tubes when the stenting function is no longer needed. Three illustrative cases are presented. In each case, the procedure took less than 30 min and had no associated morbidity. This technique allows early conversion from central venous to enteric alimentation without the need to create a second surgical enterostomy.

    1978-11-01

    Two premature infants were observed to develop behavioral and dermatologic changes and low serum zinc and copper concentrations following cessation of prolonged parenteral alimentation, while being fed exclusively with human milk. Following treatment with exogenous oral zinc supplementation, prompt relief of symptoms and increases of serum zinc and copper concentrations were observed in both infants. These patients comprise about 5% of our premature infants who are treated with parenteral alimentation for more than two weeks. We recommend that premature infants on prolonged parenteral alimentation should be monitored for changes in serum zinc and copper concentrations and, if a marked fall is observed, supplementation should be considered.

    We are managing 8 home care patients who have a gastrostomy made using an endoscopic percutaneous technique as a route of parenteral alimentation. Based on our experience, the preconditions for an endoscopic percutaneous gastrostomy as a route of parenteral alimentation are 1. normal gastrointestinal function, 2. difficulty in swallowing, 3. possibility that the caregiver can manage the gastrostomy. When we performed an endoscopic percutaneous gastrostomy as a route of parenteral alimentation for 8 home care patients, we obtained the several advantages mentioned below. 1. Swallowing pneumonia was prevented. 2. Adequate amount of alimental liquid could be infused. 3. Patient could take a bath or shower with the gastrostomy, and good QOL was realized. 4. The home care patient with the gastrostomy could have a satisfactorily long life.

    Muscle lipid concentration is known to influence pork eating quality. This study aimed at evaluating the effect of a restriction-re-alimentation feeding strategy on intramuscular fat deposition in pigs. A total of 70 Duroc × (Large White × Landrace) pigs (castrated males and females) were used. Ten pigs were first slaughtered at 30 kg live weight (LW) to determine initial body and muscle composition. From 30 to 80 kg LW (growing period), pigs were either fed ad libitum (AL) or restricted to 70% of the ad libitum intake of AL pigs (RA). From 80 to 110 kg LW (finishing period), both AL and RA pigs were fed ad libitum. In each group, pigs were slaughtered at 80 kg (n = 10) and at 110 kg (n = 20) LW. During the growing period, the growth rate of RA pigs was reduced by 30% (P alimentation up to the level observed in AL pigs (P alimentation of RA pigs increased fat tissue deposition (+160% for females, P alimentation increased lipid (+62%, P alimentation. Therefore, an increased muscle lipid concentration at 110 kg LW could not be reached in RA pigs. Modifications of onset and/or duration of restriction and re-alimentation periods should be tested to optimise effects on muscle lipid deposition and thereby achieve improved pork quality.

    The provision of enteral nutrition through the placement of gastrostomy/gastrojejunostomy tubes is a well-established procedure. Traditionally, these catheters have been placed either surgically or endoscopically; however, over the past two decades interventional radiologists have increasingly performed these procedures successfully. The perceived advantages of this route lie in the reported lower morbidity and mortality rates. In addition, percutaneous radiologically guided (PRG) catheters may be placed in certain subgroups of patients in whom it would be technically difficult or impossible by other routes, e.g., patients with head and neck or oesophageal tumours. The aim of this review is to describe the techniques of radiologically placed gastrostomy/gastrojejunostomy, discuss its indications and contraindications, describe any associated potential complications and compare PRG results with the more established techniques of open surgical and endoscopic placement. We also describe some recent procedural and catheter modifications.

    1984-09-01

    A randomized controlled study was done to determine whether the addition of heparin (1 U/mL) to peripheral intravenous alimentation solutions would affect the incidence of phlebitis and duration of patency of intravenous catheters in premature infants. Twenty-two-gauge Teflon catheters were uniformly used. One hundred five catheters infused with heparin were placed in 13 infants, and 122 catheters were placed in the control group of 13 infants. The time, nature, and incidence of complications were noted for each infusion site. Infusion of heparin was found to double the duration of patency of intravenous catheters and to reduce significantly the incidence of phlebitis. No complications related to the administration of heparin were noted. Heparinization of intravenous alimentation solutions should therefore be considered in premature infants as a means of reducing the work load and incidence of complications associated with peripheral lines.

    Due to the increased prevalence of obesity in many countries, the number of bariatric surgeries is increasing. They are considered the most effective treatment for obesity. In the postoperative there may be difficulties with the quality of alimentation, tolerance to various types of food, as well as vomiting and regurgitation. Few surveys are available to assess these difficulties in the postoperative. To perform a systematic literature review about food tolerance in patients undergoing bariatric surgery using the questionnaire "Quality of Alimentation", and compare the results between different techniques. A descriptive-exploratory study where the portals Medline and Scielo were used. The following headings were used in english, spanish and portuguese: quality of alimentation, bariatric surgery and food tolerance. A total of 88 references were found, 14 used the questionnaire "Quality of Alimentation" and were selected. In total, 2745 patients were interviewed of which 371 underwent to gastric banding, 1006 to sleeve gastrectomy, 1113 to Roux-en-Y gastric bypass, 14 to biliopancreatic diversion associated with duodenal switch, 83 were non-operated obese, and 158 non-obese patients. The questionnaire showed good acceptability. The biliopancreatic diversion with duodenal switch had the best food tolerance in the postoperative when compared to other techniques, but it was evaluated in a single article with a small sample. The longer the time after the operation, the better is the food tolerance. Comparing the sleeve gastrectomy and the Roux-en-Y gastric bypass, there are still controversial results in the literature.

  13. The Size of the Family – A Factor Influencing Alimentation and, Implicitly, the Growth and Development Processes in Teen-Agers

    Full Text Available Viewed as a phenomenon with multi-factorial determination, the growth and development of the human organism depend equally on the hereditary patrimony and on the environmental conditions, the socio-economic ones, especially. As a critical transition period from childhood to adult age, adolescence is characterized by increased nutritional needs. The main factor responsible for the variations manifested in human physical development is alimentation – a factor correlated with the socio-economic variations. Similarly with the case of other countries affected by transitions, the difficult economic transformations occurring in the Republic of Moldova have been accompanied by the installation of poverty – a phenomenon affecting especially the families formed of more than 5 members. The teen-agers of the Republic of Moldova register a deficit in the consumption of proteins, especially of animal origin, known as playing a critical role in the period of accelerated growing of the organism. Alimentation and family size are closely correlated with the socio-economic status of the family from which the child comes, while the attention and care given to the child by the family plays an essential part in the growth and development of the teen-ager. Child’s development as a function of such an element is directly related to environmental factors, as follows: alimentation is poorer in more numerous families, as the monthly income per member of family is more reduced, which is immediately reflected in a scarce alimentary consumption; hygiene is insufficient; mother’s care for the child is also reduced, etc. The study was performed on 1,525 subjects (boys and girls with ages between 10 and 16 years, all from the city of Kishinev. The main parameters considered were: stature, weight and average puberal age. The results obtained show that family size influences both the average stature of the teenagers and their weight, over the 10-16 years interval, the

    The objectives of this study were to examine systemic insulin response to a glucose tolerance test (GTT) and transcript abundance of genes of the insulin signaling pathway in skeletal muscle, during both dietary restriction and re-alimentation-induced compensatory growth. Holstein Friesian bulls were blocked to one of two groups: 1) restricted feed allowance for 125 days (period 1) (RES, n = 15) followed by ad libitum feeding for 55 days (period 2) or 2) ad libitum access to feed throughout (periods 1 and 2) (ADLIB, n = 15). On days 90 and 36 of periods 1 and 2, respectively, a GTT was performed. M. longissimus dorsi biopsies were harvested from all bulls on days 120 and 15 of periods 1 and 2, respectively, and RNA-Seq analysis was performed. RES displayed a lower growth rate during period 1 (RES: 0.6 kg/day, ADLIB: 1.9 kg/day; P alimentation (RES: 2.5 kg/day, ADLIB: 1.4 kg/day; P alimentation (P > 0.05). Genes differentially expressed in the insulin signaling pathway suggested a greater sensitivity to insulin in skeletal muscle, with pleiotropic effects of insulin signaling interrupted during dietary restriction. Collectively, these results indicate increased sensitivity to glucose clearance and skeletal muscle insulin signaling during dietary restriction; however, no overall role for insulin was apparent in expressing compensatory growth.

    This study aimed to determine the success of oral alimentation and patient retention rate 1 to 5 days after passing the Yale Swallow Protocol. Participants were 200 consecutive acute care inpatients referred for swallow assessment. Inclusion criteria were adequate cognitive abilities to participate safely, completing an oral mechanism examination, and passing the 3-ounce water swallow challenge. Exclusion criteria were altered mental status, failing the 3-ounce challenge, preadmission dysphagia, head-of-bed restrictions alimentation and retention rate. All patients who remained medically and neurologically stable drank thin liquids and ate successfully 1 to 5 days after passing the protocol. Mean (SD) volume of liquid ingested per day was 474.2 (435.5) cc. Patient retention declined steadily from day of testing (n = 200) through post-testing day 5 (n = 95). Passing the Yale Swallow Protocol allowed for initial determination of aspiration risk followed by successful oral alimentation for 1 to 5 days in medically and neurologically stable acute care hospitalized patients and without the need for instrumental dysphagia testing. The decline in patient retention was expected because of increasingly rapid transit through the acute care setting, which often renders longer follow-up problematic. © The Author(s) 2014.

    Fluctuations in availability of prey resources can impede acquisition of sufficient energy for maintenance and growth. By investigating the hormonal mechanisms of the somatotropic axis that link nutrition, fat metabolism, and lean tissue accretion, we can assess the physiological impact of decreased nutrient intake on growth. Further, species that undergo seasonal periods of reduced intake as a part of their normal life history may have a differential seasonal response to nutrient restriction. This experiment evaluated the influence of season and age on the response of the somatotropic axis, including growth hormone (GH), insulin-like growth factor (IGF)-I, and IGF-binding proteins (BP), to reduced nutrient intake and re-alimentation in Steller sea lions. Eight captive females (five juveniles, three sub-adults) were subject to 28-day periods of food restriction, controlled re-feeding, and ad libitum recovery in summer (long-day photoperiod) and winter (short-day photoperiod). Hormone concentrations were insensitive to type of fish fed (low fat pollock vs. high fat herring), but sensitive to energy intake. Body mass, fat, and IGF-I declined, whereas GH and IGFBP-2 increased during feed restriction. Reduced IGF-I and IGFBP with increased GH during controlled re-feeding suggest that animals did not reach positive energy balance until fed ad libitum. Increased IGF-I, IGFBP-2, IGFBP-3, and reduced GH observed in summer reflected seasonal differences in energy partitioning. There was a strong season and age effect in the response to restriction and re-alimentation, indicating that older, larger animals are better able to cope with stress associated with energy deficit, regardless of season.

    The Nutrition Support Team (NST) assessed the severity of dysphagia in elderly patients admitted to the internal medical department, and the appropriate nutritional treatment was determined. Patients were treated with either oral nutrition (enteral nutrition, EN) or artificial alimentation (parenteral nutrition, PN). The goal of this study was to analyze whether or not the route of nutrition affected the patient discharge rates. We divided 290 elderly inpatients with dysphagia into 2 groups, the pneumonia group (200 patients) and the non-pneumonia group (90 patients). The NST estimated the swallowing function using the Fujishima dysphagia scale. Monitoring was continued until the NST care and treatment had been finalized. We further divided the pneumonia patients into two subgroups: those with a Fujishima dysphagia scale score ≤3 or ≥4 at the beginning of NST intervention. The changes in the swallowing function were analyzed.The swallowing function in the patients with a score ≥4 was significantly improved compared with that in the patients with a score ≤3. This difference, however, was not observed in the non-pneumonia group. In both the pneumonia and non-pneumonia groups, the ratio of patients discharged on oral nutrition was one-third, and the ratio of death in hospital was one-quarter, the remaining patients required artificial alimentation. Among elderly patients admitted to the internal medical department of the emergency hospital with dysphagia, one-third left the hospital with oral nutritional intake, one-quarter died in hospital, and the remaining required artificial alimentation.

    Deficient nutrition is a common pathological factor encountered in medical practice. We evaluated results of combined intake of Essentuki-Novaya mineral water and Nutridrink artificial food mixture (Nutritia, Holland). Spa and resort therapy based on the use of natural factors and well-balanced nutrition resulted in the marked alleviation of clinical symptoms in patients with gastrointestinal disorders. Simultaneously, the consequences of deficient nutrition in the preceding period were corrected and manifestations of the main pathological syndromes decreased. It is concluded that a short-term course of oral alimentation using food substrate mixtures had beneficial effect on the health state of patients by improving their nutritional status and quality of life.

    Full Text Available RESUMO: Nos últimos anos, a banana verde tem despertado interesse do mercado consumidor, pois, além do aspecto nutricional, destaca-se a presença de compostos funcionais, em especial o amido resistente. Contudo, sua adstringência limita seu consumo e sua comercialização em forma de farinhas é a principal forma de consumo e utilização, como ingrediente funcional. O objetivo do presente trabalho foi avaliar os potenciais usos da farinha de banana verde (FBV na elaboração de produtos alimentícios e os principais métodos de obtenção, e seus efeitos sobre a qualidade físico-química, sensorial e funcional das farinhas obtidas. Fatores como tipo de cultivar ou variedade da fruta, presença ou ausência de casca, técnica de desidratação e condições de operação do equipamento influenciam as características físico-químicas, tecnológicas e funcionais da FBV. A FBV tem sido utilizada como ingrediente funcional na elaboração de diferentes produtos alimentícios, como pão, biscoito cookie, pré-mistura de bolo, snacks, nuggets e, sobretudo, na elaboração de massas alimentícias. De forma geral, o emprego de FBV e produtos alimentícios promove a melhoria de suas propriedades funcionais, devido ao aumento do teor de amido resistente, compostos fenólicos e da atividade antioxidante. A FBV também reduz o teor e a porcentagem de hidrólise do amido digerível e, consequentemente, do índice glicêmico dos produtos, que apresentaram potencial para compor a dieta, principalmente de indivíduos diabéticos e obesos. A FBV pode ser amplamente utilizada tanto pela indústria de alimentos (pães, biscoitos, macarrão, etc., como ingrediente na preparação de pratos prontos e na elaboração de produtos cárneos.

    Changes in the plasma and urine levels of the trace metal zinc have been followed in a series of 37 adult patients totally supported by intravenous alimentation. Copper has also been determined in more recent cases. In such a seriously ill group, although urinary zinc loss may be very high at the height of catabolism, severe plasma depletion does not occur unless there is a subsequent phase of sustained anabolism and weight gain. In four patients plasma zinc fell to very low levels during this phase and three of this group developed a syndrome characterized by diarrhea, mental depression, para-nasal, oral and peri-oral dermatitis, and alopecia. The response to oral or intravenous zinc therapy is striking, except for hair regrowth which is delayed but eventually complete. The syndrome we have recognized in adult man has not been previously described. It resembles however the parakeratosis of zinc deficient swine and it is also very similar to Acrodermatitis enteropathica, a genetically determined disorder of infants very recently linked to zinc deficiency. Zinc is clearly essential to human metabolism and it should be included in all parenteral alimentation regimes particularly during the period of rapid, sustained, weight gain. Images Fig. 1. Fig. 2.

    The nutritional support is one of the important therapeutic strategies for the elderly patients with severe sepsis, but there is controversial in choosing a parenteral nutrition formulation. This study was designed to compare the therapeutic effects of structured lipid emulsion, physically mixed medium, and long-chain fat emulsion in the treatment of severe sepsis in elderly patients. A total number of 64 elder patients with severe sepsis were enrolled in the study. After a week of enteral nutritional support, the patients were randomly divided into research (structured lipid emulsion as parenteral alimentation) and control groups (physically mixed medium and long-chain fat emulsion as parenteral alimentation). The alterations of plasma albumin, lipid metabolism, and blood glucose level were recorded after parenteral alimentation and were compared between the two groups. The plasma levels of albumin, prealbumin, cholesterol, and triglyceride were decreased in all the patients after one week of enteral nutritional support treatment (t = 7.78, P = 0.000; t = 10.21, P = 0.000; t = 7.99, P = 0.000; and t = 10.99, P = 0.000). Further parenteral alimentation with different lipid emulsions had significant effects on the serum prealbumin and albumin (t = 3.316, P = 0.002; t = 3.200, P = 0.002), whilst had no effects on the blood glucose and triglyceride level (t = 7.78, P = 0.000; t = 4.228, P = 0.000). In addition, the two groups had a significantly different Apache II score, ventilator time, and hospital stay time (t = -2.213, P = 0.031; t = 2.317, P = 0.024; t = 2.514, P = 0.015). The structured lipid emulsion was safe as parenteral nutrition for elderly patients with severe sepsis. It was demonstrated to be superior to the physically mixed medium and long-chain fat emulsion with respect to the protein synthesis and prognosis.

    With the aim of assessing the possible benefits of nutritional therapy , 140 patients were prospectively studied during radiotherapy of the head and neck (81%) and esophageal cancer (19%). Mean age was 56.0 (17-80), with 114 males and 26 females. Duration of both nutrition and radiotherapy was 78.0 ± 45 days. Tube feeding was the primary modality in 50.7% of the population, and oral regimens in the remaining 49.3%, but associations between the methods were also used. Enteral diets were supplied under the supervision of a specialized tem for home alimentation (PROSNED). Compliance to the program was 100% and a lymphocyte count diminished along this period (1933 ± 1033 vs 1265 ± 688, p.0.001). A subjective improvement was reported by 84% of the population, and total calorie intake, that was below 60% of estimated needs in 100% of the cases initially, significantly improved to just 40% inadequate at the end of the observations. Radiotherapy was associated with mucositis in 21% of the patients, taste changes in 79%, xerostomy in 81%, anorexia in 66% and odinophagia in 59%. In the individuals selected for enteral feeding, side effects were represented by technical problems (20%) and gastrointestinal disorders (13%). All patients completed the nutritional support program and there was no mortality in this series. It is conclude that: early nutritional support during radiotherapy was able to maintain or improve the nutritional status; tube feeding, alone or in combination with oral diets, was indicated whenever appropriate and contributed to fulfillment of the energy requirements; reduction of total lymphocytes could not be prevented by the mentioned therapy; complications of enteral alimentation were mild and affected a small proportion of the population; troubles induced by radiotherapy were as frequent as expected, and tended to disturb the intake of the food; the compliance of the therapeutic plan was excellent and can be attributed to the efforts of the

    Total parenteral alimentation (TPA) was delivered to 80 infants via indwelling umbilical artery and to 9 via indwelling umbilical venous catheters. The primary indication for catheter placement and maintenance was monitoring of arterial blood gases (umbilical venous catheter tip in left atrium) in a group of sick neonates requiring increased inspired oxygen or assisted ventilation. Results were compared with those from 23 infants who had tunnelled jugular catheters for a variety of chronic medical and surgical problems preventing gastric or intestinal feeding. A mean weight gain was achieved in both groups. Mortality and morbidity rates were similar in both groups. The most common complications were infection and thrombotic phenomena. Metabolic complications were few. It is concluded that infusing TPA solutions via indwelling umbilical catheters presents no greater risk than infusion via tunnelled jugular catheters, and provides a method for supplying adequate caloric intake for growth during the acute stage of illness.

    1988-09-01

    We determined metabolic responses after enteric galactose alimentation in 5- to 7-day-old newborn rats fasted for 24 h. The glycemic response was attenuated after enteric galactose feeding compared with the response after enteric glucose-fed rat pups. 14C radioactivity in blood from galactose-fed pups was reduced as counts in blood galactose were lower than counts in blood glucose in glucose-fed pups. Nonetheless within 15 min, [14C] from galactose appeared in blood glucose suggesting rapid conversion of galactose to glucose. The plasma insulin response was also attenuated after galactose feeding compared with the insulin response after enteric glucose. Hepatic glycogen content increased rapidly after enteric galactose feeding and was higher than after glucose feeding at 60, 120, and 180 min. Significant glycogen synthesis after oral glucose was delayed and occurred at 240 min. Carbon radioactivity in glycogen was higher in galactose fed pups between 15 and 360 min of the study. Serial determination of hepatic metabolites revealed an increase of galactose-1-phosphate levels after oral galactose at 240 and 300 min and a transient decline of ATP at 15 min. Other hepatic metabolites did not demonstrate significant differences between the two groups. These data suggest that hepatic glycogen synthesis is more rapid and occurs sooner after galactose than after glucose alimentation in previously fasted newborn rats. Galactose may enter a more direct pathway for neonatal hepatic glycogen synthesis. The relatively delayed entry of glucose label into hepatic glycogen and the delay of net glycogen synthesis after oral glucose suggest that glucose entry is not direct and may require further metabolism before incorporation into glycogen.(ABSTRACT TRUNCATED AT 250 WORDS)

  17. Artificial hydration and alimentation at the end of life: a reply to Craig.

    Science.gov (United States)

    Ashby, M; Stoffell, B

    1995-06-01

    Dr Gillian Craig (1) has argued that palliative medicine services have tended to adopt a policy of sedation without hydration, which under certain circumstances may be medically inappropriate, causative of death and distressing to family and friends. We welcome this opportunity to defend, with an important modification, the approach we proposed without substantive background argument in our original article (2). We maintain that slowing and eventual cessation of oral intake is a normal part of a natural dying process, that artificial hydration and alimentation (AHA) are not justified unless thirst or hunger are present and cannot be relieved by other means, but food and fluids for (natural) oral consumption should never be 'withdrawn'. The intention of this practice is not to alter the timing of an inevitable death, and sedation is not used, as has been alleged, to mask the effects of dehydration or starvation. The artificial provision of hydration and alimentation is now widely accepted as medical treatment. We believe that arguments that it is not have led to confusion as to whether or not non-provision or withdrawal of AHA constitutes a cause of death in law. Arguments that it is such a cause appear to be tenuously based on an extraordinary/ordinary categorisation of treatments by Kelly (3) which has subsequently been interpreted as prescriptive in a way quite inconsistent with the Catholic moral theological tradition from which the distinction is derived. The focus of ethical discourse on decisions at the end of life should be shifted to an analysis of care, needs, proportionality of medical interventions, and processes of communication.

    Many complications of central venous catheters, which include perforation of the vessel walls and extravasation of the infusate into pericardial, pleural, and peritoneal cavities, have been reported. We report an infant with a central venous catheter in inferior vena cava who experienced extravasation of parenteral alimentation fluid into the right renal pelvis secondary to perforation of the renal vein. To our knowledge, this rare complication has not been reported earlier.

    Sixteen Hereford bulls (16 mo of age, 462 kg average body weight) were used in each of 2 yr to evaluate the effects of hypovitaminosis A on seminal quality and sperm production. Bulls were fed a high-concentrate diet with (+VIT) or without (-VIT) supplemental Vitamin A until the apparent onset of hypovitaminosis A (28 and 32 wk in Year 1 and 2, respectively). Half of the bulls on each treatment were then slaughtered and those remaining were re-alimented with Vitamin A. Plasma retinol concentration in -VIT bulls reached a nadir at approximately 25 wk. In Year 1, the proportion of progressively motile spermatozoa was lower in -VIT bulls after 17 wk but returned to that of the +VIT group after re-alimentation. The proportion of spermatozoa with primary morphological defects appeared to be greater in -VIT bulls compared to +VIT bulls by 26 and 24 wk in Year 1 and 2, respectively. The incidence of these defects declined in -VIT bulls upon re-alimentation, and approached the incidence observed in +VIT bulls by 8 to 12 wk of re-alimentation. Hypovitaminosis A decreased paired testes weight, daily sperm production, and epididymal sperm reserves but did not affect daily gain. Prolonged dietary Vitamin A deficiency impaired semen quality and sperm production in the absence of other clinical symptoms. However, under practical feeding conditions, diets that result in long-term, marginal Vitamin A deficiency or a relatively short-term absence of Vitamin A intake probably would have minimal effects on spermatogenesis.

    Compensatory growth (CG), an accelerated growth phenomenon which occurs following a period of dietary restriction is utilised worldwide in animal production systems as a management practise to lower feed costs. The objective of this study was to evaluate the contribution of jejunal epithelial to CG in cattle through transcriptional profiling following a period of dietary restriction as well as subsequent re-alimentation induced CG. Sixty Holstein Friesian bulls were separated into two groups; RES and ADLIB, with 30 animals in each. RES animals were offered a restricted diet for 125 days (Period 1) followed by ad libitum feeding for 55 days (Period 2). ADLIB animals had ad libitum access to feed across both periods 1 and 2. At the end of each period, 15 animals from each treatment group were slaughtered, jejunal epithelium collected and RNAseq analysis performed. Animals that were previously diet restricted underwent CG, gaining 1.8 times the rate of their non-restricted counterparts. Twenty-four genes were differentially expressed in RES compared to ADLIB animals at the end of Period 1, with only one gene, GSTA1, differentially expressed between the two groups at the end of Period 2. When analysed within treatment (RES, Period 2 v Period 1), 31 genes were differentially expressed between diet restricted and animals undergoing CG. Dietary restriction and subsequent re-alimentation were associated with altered expression of genes involved in digestion and metabolism as well as those involved in cellular division and growth. Compensatory growth was also associated with greater expression of genes involved in cellular protection and detoxification in jejunal epithelium. This study highlights some of the molecular mechanisms regulating the response to dietary restriction and subsequent re-alimentation induced CG in cattle; however the gene expression results suggest that most of the CG in jejunal epithelium had occurred by day 55 of re-alimentation.

    In a prospective controlled clinical study 30 patients with moderate degree of malnutrition, normal liver and kidneys, and a functioning gastrointestinal tract were randomized to receive a free amino acid and small peptide enteral diet (15 patients) or an isonitrogenous isocaloric parenteral support for at least 10 days (total energy: 2900 kcal, nitrogen: 14.5 g, carbohydrates: 380 g, fat: 112 g, N/non protein calories: 1/175). The parenteral and enteral diets had the same protein/lipid/carbohydrate composition. The data indicated that both routes led to positive nitrogen balance. Nitrogen equilibrium was achieved by day 3 in the TPN group and by day 5 in the enteral group. There were no significant changes in serum albumin within either group. Serum level of transferrin reached a significant increase in both groups (p = 0.003). Thyroxine-binding prealbumin rose significantly in both groups as well (p = 0.019 and 0.004 respectively). Statistically significant rises in lymphocyte counts (p = 0.003 and 0.001 respectively), in levels of C3 (p = 0.009 and 0.001 respectively), IgA (p = 0.002), IgG (p = 0.004 and 0.003 respectively) and IgM (p = 0.004) occurred in either treatment group. There was a high incidence of negative skin tests at the start of the study in the enteral group (73.3%) and the TPN group (60%). By the end of the study the incidence of negative results for this test was 40.0% and 26.6% respectively. Despite maintenance of similar glucose levels in both groups, TPN led to significantly (p = 0.000) higher serum insulin levels. The serum insulin increased almost linearly over the study period, and eventually prevented fat mobilization and lipolysis, so that free fatty acid levels had fallen significantly (p = 0.000). A significant elevation of the liver enzymes over the study period occurred in the TPN group, but not in the enterally fed patients. The present findings provide no evidence that semi-elemental diets are in any way inferior to isonitrogenous isocaloric regimes parenterally given for a short period of time.

    Protein-energy homeostasis is a major determinant of healthy aging. Inadequate nutritional intakes and physical activity, together with endocrine disturbances are associated with of sarcopenia and frailty. Guidelines from scientific societies mainly address the quantitative aspects of protein and energy nutrition in elderly. Besides these quantitative aspects of protein load, perspective strategies to promote muscle protein synthesis and prevent sarcopenia include pulse feeding, the use of fast proteins and the addition of leucine or citrulline to dietary protein. An integrated management of sarcopenia, taking into account the determinants of muscle wasting, i.e. nutrition, physical activity, anabolic factors such as androgens, vitamin D and n-3 polyunsaturated fatty acids status, needs to be tested in the prevention and treatment of sarcopenia. The importance of physical activity, specifically resistance training, is emphasized, not only in order to facilitate muscle protein anabolism but also to increase appetite and food intake in elderly people at risk of malnutrition. According to present data, healthy nutrition in elderly should respect the guidelines for protein and energy requirement, privilege a Mediterranean way of alimentation, and be associated with a regular physical activity. Further issues relate to the identification of the genetics determinants of protein energy wasting in elderly. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Crohn's disease (CD) often flares up and requires frequent hospitalization and/or surgery. Cyclic home elemental enteral alimentation (C-HEEA) was developed to prevent flare-up of CD and to minimize patient hospitalization. However, its therapeutic efficacy has not been studied in a large patient population. Therefore, questionnaires were sent to members of the Inflammatory Bowel Disease (IBD) Research Group of Japan to evaluate the therapeutic efficacy of C-HEEA and to define the factors that may affect the efficacy of the treatment. Data for 410 patients (C-HEEA-treated n = 322; drug-treated n = 88) were collected from 29 institutions and analysis showed the following results. The cumulative remission and non-hospitalization rates of the C-HEEA treated group were significantly higher than the rates of the drug-treated group in all patients and in those with ileitis and ileo-colitis (P < 0.0001, P < 0.001, and P < 0.01, respectively), but no significant difference was noted in patients with colitis. Cumulative remission and non-hospitalization rates were also influenced by the daily calorie content of the elemental diet (ED); more than 1200 kcal of the ED per day was found to be more effective than lower amounts to maintain remission and to prevent hospitalization. The therapeutic efficacy of C-HEEA was shown to be superior to that of drug treatment in patients with CD with ileal involvement, and it is suggested that more than 1200kcal per day should be supplied by the ED to enhance its therapeutic efficacy.

At the end of Period 1, 64 DEGs were identified between RES and ADLIB, with only one DEG identified at the end of Period 2. When analysed within RES treatment (RES, Period 2 v Period 1, 411 DEGs were evident. Genes identified as differentially expressed in response to both dietary restriction and subsequent CG included those involved in processes such as cellular interactions and transport, protein folding and gene expression, as well as immune response. This study provides an insight into the molecular mechanisms underlying the expression of CG in rumen papillae of cattle; however the results suggest that the role of the ruminal epithelium in supporting overall animal CG may have declined by day 55 of re-alimentation.

    Compensatory growth (CG) is an accelerated growth phenomenon observed in animals upon re-alimentation following a period of dietary restriction. It is typically utilised in livestock systems to reduce feed costs during periods of reduced feed availability. The biochemical mechanisms controlling this phenomenon, however, are yet to be elucidated. This study aimed to uncover the molecular mechanisms regulating the hepatic expression of CG in cattle, utilising RNAseq. RNAseq was performed on hepatic tissue of bulls following 125 days of dietary restriction (RES) and again following 55 days of subsequent re-alimentation during which the animals exhibited significant CG. The data were compared with those of control animals offered the same diet on an ad libitum basis throughout (ADLIB). Elucidation of the molecular control of CG may yield critical information on genes and pathways which could be targeted as putative molecular biomarkers for the selection of animals with improved CG potential. Following a period of differential feeding, body-weight and liver weight were 161 and 4 kg higher, respectively, for ADLIB compared with RES animals. At this time RNAseq analysis of liver tissue revealed 1352 significantly differentially expressed genes (DEG) between the two treatments. DEGs indicated down-regulation of processes including nutrient transport, cell division and proliferation in RES. In addition, protein synthesis genes were up-regulated in RES following a period of restricted feeding. The subsequent 55 days of ad libitum feeding for both groups resulted in the body-weight difference reduced to 84 kg, with no difference in liver weight between treatment groups. At the end of 55 days of unrestricted feeding, 49 genes were differentially expressed between animals undergoing CG and their continuously fed counterparts. In particular, hepatic expression of cell proliferation and growth genes were greater in animals undergoing CG. Greater expression of cell cycle and cell

    Adjustable gastric banding and vertical banded gastroplasty are associated with the worst postoperative food tolerance of all bariatric techniques. However, food tolerance tends to improve over time. The aim of this study was to assess food tolerance and diet quality in patients undergoing a sleeve gastrectomy, 1 and 5 years after surgery. A prospective observational study of all the morbidly obese patients undergoing laparoscopic sleeve gastrectomy was performed. Food tolerance was assessed using the Quality of Alimentation questionnaire validated in bariatric patients. Ninety-three patients were analyzed. One year after surgery, mean excess weight loss (EWL) was 81.1% ± 8.3%, and 5 years after surgery, mean EWL was 79.9% ± 6.4%. Preoperatively, 39.8% of patients perceived their eating patterns as good or excellent, 1 year after surgery, 79.6% and 5 years postoperatively, 86%. One year after surgery, the patients reported some difficulty in tolerance of rice, pasta, and red meat. Five years after surgery, these difficulties disappeared and very few patients just refer some tolerance difficulties with red meat. One year after surgery, 10% of the patients reported that they suffered postprandial vomiting often and 22% rarely. Five years postoperatively, only 8% of subjects describe rarely vomiting. After sleeve gastrectomy, the patients recognize an improvement in the quality of alimentation. During the first postoperative year, they present tolerance problems with rice, pasta, and red meat, and that disappeared 5 years after surgery.

    In the recent medical ethics literature, several authors have recommended terminal sedation and refusal of hydration and nutrition as important, morally acceptable, and relatively uncontroversial treatment options for end-of-life suffering. However, not all authors use these terms to refer to the same practices. This paper examines the various ways that the terms terminal sedation and refusal of hydration and nutrition have been used in the medical literature. Although some of these practices are ethically appropriate responses to end-of-life suffering, others (at least as they are currently described in the medical ethics literature) are not. This paper identifies and discusses the principles that morally distinguish these practices from one another and specifically describes different features of medical practices and moral principles that affect the moral acceptability of various medical treatments. These distinctions reveal the complexity of the issues surrounding terminal sedation and refusal of hydration and nutrition, a complexity that has not been adequately addressed in recent discussions.

Distinct proportions of BR: SER respectively were used, amounting to five treatments: 1:0 (A; 3:1 (B; 1:1 (C; 1:3 (D and 0:1(E and fixed amounts of the other components. For the statistical analysis, variance analysis and the Tukey test were performed to 5% significance. The moisture, protein, lipid, ash, mineral, and dietary fiber contents were directly increased as the SER was increased and the amount of BR was decreased. However, the opposite was found with both carbohydrates and calories. The soluble solids, pH and water activity values presented increases with the increased soybean extract residue. All the treatments presented slightly acidic pH and water activity bellow 0.6, favoring microbiological safety. In the chemical score, treatment A presented lysine as the limiting aminoacid in relation to the Food and Agriculture Organization - FAO/WHO reference (1990. The food bars can be considered rich in dietary fiber and with considerable nutritional support.

    Compensatory growth (CG), an accelerated growth phenomenon which occurs following a period of dietary restriction is exploited worldwide in animal production systems as a method to lower feed costs. However the molecular mechanisms regulated CG expression remain to be elucidated fully. This study aimed to uncover the underlying biology regulating CG in cattle, through an examination of skeletal muscle transcriptional profiles utilising next generation mRNA sequencing technology. Twenty Holstein Friesian bulls were fed either a restricted diet for 125 days, with a target growth rate of 0.6 kg/day (Period 1), following which they were allowed feed ad libitum for a further 55 days (Period 2) or fed ad libitum for the entirety of the trial. M. longissimus dorsi biopsies were harvested from all bulls on days 120 and 15 of periods 1 and 2 respectively and RNAseq analysis was performed. During re-alimentation in Period 2, previously restricted animals displayed CG, growing at 1.8 times the rate of the ad libitum control animals. Compensating animals were also more feed efficient during re-alimentation and compensated for 48% of their previous dietary restriction. 1,430 and 940 genes were identified as significantly differentially expressed (Benjamini Hochberg adjusted P < 0.1) in periods 1 and 2 respectively. Additionally, 2,237 genes were differentially expressed in animals undergoing CG relative to dietary restriction. Dietary restriction in Period 1 was associated with altered expression of genes involved in lipid metabolism and energy production. CG expression in Period 2 occurred in association with greater expression of genes involved in cellular function and organisation. This study highlights some of the molecular mechanisms regulating CG in cattle. Differentially expressed genes identified are potential candidate genes for the identification of biomarkers for CG and feed efficiency, which may be incorporated into future breeding programmes.

    To study the effect of fast-food-based hyper-alimentation on liver enzymes and hepatic triglyceride content (HTGC). Prospective interventional study with parallel control group. University Hospital of Linköping, Sweden. 12 healthy men and six healthy women with a mean (SD) age of 26 (6.6) years and a matched control group. Subjects in the intervention group aimed for a body weight increase of 5-15% by eating at least two fast-food-based meals a day with the goal to double the regular caloric intake in combination with adoption of a sedentary lifestyle for 4 weeks. Weekly changes of serum aminotransferases and HTGC measured by proton nuclear magnetic resonance spectroscopy at baseline and after the intervention. Subjects in the intervention group increased from 67.6 (9.1) kg to 74.0 (11) kg in weight (p19 U/l, men >30 U/l) during the intervention. Sugar (mono- and disaccharides) intake during week 3 correlated with the maximal ALT/baseline ALT ratio (r = 0.62, p = 0.006). HTGC increased from 1.1 (1.9)% to 2.8 (4.8)%, although this was not related to the increase in ALT levels. ALT levels were unchanged in controls. Hyper-alimentation per se can induce profound ALT elevations in less than 4 weeks. Our study clearly shows that in the evaluation of subjects with elevated ALT the medical history should include not only questions about alcohol intake but also explore whether recent excessive food intake has occurred.

    Full Text Available Compensatory growth (CG, an accelerated growth phenomenon which occurs following a period of dietary restriction is exploited worldwide in animal production systems as a method to lower feed costs. However the molecular mechanisms regulated CG expression remain to be elucidated fully. This study aimed to uncover the underlying biology regulating CG in cattle, through an examination of skeletal muscle transcriptional profiles utilising next generation mRNA sequencing technology. Twenty Holstein Friesian bulls were fed either a restricted diet for 125 days, with a target growth rate of 0.6 kg/day (Period 1, following which they were allowed feed ad libitum for a further 55 days (Period 2 or fed ad libitum for the entirety of the trial. M. longissimus dorsi biopsies were harvested from all bulls on days 120 and 15 of periods 1 and 2 respectively and RNAseq analysis was performed. During re-alimentation in Period 2, previously restricted animals displayed CG, growing at 1.8 times the rate of the ad libitum control animals.

    In the last 20 years, Public Health Nutrition focused mainly on the qualitative aspects which may influence the onset of chronic diseases, quality of life, physical and mental performance and life expectancy. This applied knowledge organised as part of preventive and health promotion programs led to the development of Community Nutrition. The aim of Community Nutrition actions is to adequate lifestyles related to food consumption patterns in order to improve the quality of life and contribute to health promotion of the population in the community where programs and services are delivered. Key functions to develop in a Community Nutrition Unit consist in the identification and assessment of nutrition problems in the community as well as the design, implementation and evaluation of intervention programs by means of appropriate strategies. These should aim at different populations groups and settings, such as work places, schools, high risk groups or the general public. Nowadays, Community Nutrition work efforts should focus on three main aspects: nutrition education in schools and in the community; food safety and food security and the development and reinforcement of food preparation skills across all age groups. Social catering services, either in schools, the work place or at the community level, need to ensure adequate nutritional supply, provide foods contributing to healthy eating practices as well as to enhance culinary traditions and social learning. Food safety and food security have become a top priority in Public Health. The concepts referes to the availability of food safe and adequate as well as in sufficient amount in order to satisfy nutrition requirements of all individuals in the community. Social changes along new scientific developments will introduce new demands in Community Nutrition work and individual dietary counselling will become a key strategy. In order to face new challenges, community nutrition pactitioners require a high quality

    Full Text Available Due to higher energy consumption, physically active people have higher nutritional requirements. In addition to other important factors for sports, such as good health and physical predisposition, adequate nutrition is a fundamental component. Sports nutrition must be well planned and individually adapted based on physical characteristics, tendencies towards gaining or losing weight, frequency, duration and intensity of training sessions. Studies have shown that a well-balanced ratio of macro and micronutrients, with the support of supplements and adequate hydration, can significantly improve athletic performance and plays a key role in achieving better results. An optimally designed nutritional program, with realistic and achievable goals, which complements a well-planned training program, is the basis for success in sports. Only when nutritional requirements are met, deficits can be prevented and performance in sport pushed to the limit.

    A revision was made on files of newborns whom received total parenteral nutrition (TPN) in the neonatal intensive care unit of the Hospital Infantil de Tamaulipas during a two and a half years period. We try to correlate dosage and caloric intake with weight gain, survival and complications. We reviewed the principal indications that motivated the use of total parenteral nutrition. The average period of administration was 15 days and caloric intake average 75 cal. There was significance in weight gain in newborns older than 35 weeks (14.6 g/kg/day) compared with younger than 34 weeks (9.2 g/kg/day) (p less than 0.001). There was no relation between days and dosage in both groups. Only one case showed cholestatic jaundice. Hyperglycemia was present statistically more frequent in the group lesser gestational age. There were no important electrolytic disturbances. Necrotizing enterocolitis was present more frequent in the older group. Some comments are made in relation to sepsis and a discussion of possible causes that do no permit a better assimilation of nutrients in these babies.

    Four groups of five non-lactating and non-pregnant Belgian Blue double-muscled (BBDM) cows were used to investigate the effect of energy level (E) on digestion, and blood and urine metabolites. The energy levels of the groups, applied indoors during a 140-day restriction period, were 100%, 90%, 80% or 70% of their energy requirements (E100, E90, E80, E70) respectively. Afterwards, animals grazed on the same swards for 203 days (re-alimentation period). Balance trials were conducted at the end of the restriction period (BT1) and at the end of the re-alimentation period (BT2). Blood was sampled at the end of these trials. Diets consisted of maize silage and straw (80/20 on a dry matter basis) and a mineral-vitamin premix, fed at the appropriate E during BT1, or maize silage and a mineral-vitamin premix, fed at 125% of the maintenance requirements, during BT2. Significant increases of the digestibility coefficients were found during BT1 when E decreased, resulting in a better net energy capture of 7% for E70 compared with E100 (p < 0.05). Slightly, but non-significantly higher digestibility coefficients were observed for decreasing E during BT2. Plasma concentrations of glucose and creatinine did not differ between treatments during BT1, while differences were found for triacylglycerols and alpha-amino nitrogen. A tendency for a linear increase was observed for non-esterified fatty acids with decreasing E. Differences in blood metabolite concentrations disappeared in BT2. Urinary creatinine excretion was not affected by E, while body nitrogen loss increased linearly with energy restriction in BT1. No differences were found during BT2, suggesting that non-lactating and non-pregnant BBDM cows are able to adapt to a cyclic change of body weight and body reserves. These data show that restricted cows mobilized body fat as well as body protein. It is concluded that the qualitative aspects of metabolism during energy restriction are comparable in double-muscled cows with

Mais la récolte des quantités nécessaires, au moment voulu, devient très délicate dès que l'on dépasse l'échelle de l'aquarium. Le développement, ces dernières décennies, de techniques de production en masse d'animaux-proies a permis le lancement d'élevages à grande échelle. Parmi ces proies, le Branchiopode Artemia salina et le Rotifère Brachionus plicatilis dominent incontestablement ; tandis que l'élevage des Copépodes, part la plus intéressante du plancton naturel, reste encore mal maîtrisé. Cependant , l'élevage et l'emploi de proies vivantes, quelles qu'elles soient, imposent la réalisation d'installations coûteuses et l'emploi d'un abondant personnel qualifié. Il en est résulté récemment un important effort de recherche en direction de nourritures inertes, broyats , poudres et aliments composés, généralement abandonnés après les échecs enregistrés pendant les premières années du siècle. Quelques résultats encourageants ont été obtenus, mais ils restent limités et soulèvent de délicats problèmes d'hygiène des bacs d'élevage.

    Full Text Available L’alimentation dans les négro-cultures en général et chez les Bulu en particulier revêt une importance qui va bien au-delà de la satisfaction organoleptique. En effet, elle intervient dans la société comme un fait social total permettant de l’appréhender sous l’angle politique, économique, médical, religieux, artistique, juridique, linguistique. Du point de vue linguistique, les proverbes constituent un espace propice à la démonstration des représentations autour de l’aliment. Utilisés pour illustrer une situation, donner une leçon ou encore appuyer un discours, les proverbes sont un canevas linguistique dont on ne peut se passer dans les joutes oratoires. Pour ce qui concerne est des proverbes alimentaires, on peut se rendre compte qu’ils permettent d’observer comment les Bulu appréhendent le monde et montrent de ce fait la société dans sa dimension holistique. Cet article s’attèle à une analyse anthropologique de quelques proverbes alimentaires de la socioculture bulu. Ces parémies font intervenir la vision bulu de l’organisation politique, de l’économie, des relations de parenté, de la diplomatie, de l’education, de la mort, de la justice, de la construction de la personnalité,etc. Feeding in negro-cultures generally and particularly on Bulu’s people have an importance which goes beyond the biological needs. In fact, it intervenes in this society as a social total fact and permits to apprhehend it on political, economical, medical, religious, artistic, juridical, linguistic angle. From the linguistic point of view, proverbs constitute a favorable space to the demonstration of representations on food. Used to illustrate a situation, to give a learning or to support a speech, proverbs are a linguistic framework which is not possible to avoid during verbal sparrings. Concerning food proverbs, it can be realized that, they permit to observe how Bulu’s people apprehend world and show society in this

    Parenteral alimentation is often complicated by Candida albicans infection which may be fatal. This study investigated the effect of alimentation fluid (Aminosol) on C. albicans' growth in vitro. It was found that concentrated Aminosol (1400 millisomoles) maintained C. albicans in a viable state but inhibited replication. Dilution of alimentation fluid to physiological concentrations (300 milliosmoles) with either saline or aged pooled normal sera promoted in vitro growth of C. albicans which was equivalent to that obtained in BHI broth and was slightly less than that obtained in Sabouraud's broth. The effects of fresh sera with full complement activity were also investigated. In fresh sera appropriately diluted with physiological saline, some clumping of the yeasts was observed and all formed germ tubes. Growth as defined by budding or the formation of hyphae was inhibited. When Aminosol was diluted to 300 milliosomoles with fresh sera, all yeasts were noted to be in clumps with germ tubes as well as continually growing hyphae. Growth was approximately equal to that seen in Aminosol similarly diluted with saline.

    Optimal nutrition will be critical for crew members who embark on space exploration missions. Nutritional assessment provides an opportunity to ensure that crewmembers begin their missions in optimal nutritional status, to document changes during a mission and, if necessary, to provide intervention to maintain that status throughout the mission, and to assesses changes after landing in order to facilitate the return to their normal status as soon as possible after landing. We report here the findings from our nutritional assessment of astronauts who participated in the International Space Station (ISS) missions, along with flight and ground-based research findings. We also present ongoing and planned nutrition research activities. These studies provide evidence that bone loss, compromised vitamin status, and oxidative damage are the critical nutritional concerns for space travelers. Other nutrient issues exist, including concerns about the stability of nutrients in the food system, which are exposed to longterm storage and radiation during flight. Defining nutrient requirements, and being able to provide and maintain those nutrients on exploration missions, will be critical for maintaining crew member health.

    1983-01-01

    The concept of nutritional surveillance is derived from disease surveillance, and means "to watch over nutrition, in order to make decisions that lead to improvements in nutrition in populations". Three distinct objectives have been defined for surveillance systems, primarily in relation to problems of malnutrition in developing countries: to aid long-term planning in health and development; to provide input for programme management and evaluation; and to give timely warning of the need for intervention to prevent critical deteriorations in food consumption. Decisions affecting nutrition are made at various administrative levels, and the uses of different types of nutritional surveillance information can be related to national policies, development programmes, public health and nutrition programmes, and timely warning and intervention programmes. The information should answer specific questions, for example concerning the nutritional status and trends of particular population groups.Defining the uses and users of the information is the first essential step in designing a system; this is illustrated with reference to agricultural and rural development planning, the health sector, and nutrition and social welfare programmes. The most usual data outputs are nutritional outcome indicators (e.g., prevalence of malnutrition among preschool children), disaggregated by descriptive or classifying variables, of which the commonest is simply administrative area. Often, additional "status" indicators, such as quality of housing or water supply, are presented at the same time. On the other hand, timely warning requires earlier indicators of the possibility of nutritional deterioration, and agricultural indicators are often the most appropriate.DATA COME FROM TWO MAIN TYPES OF SOURCE: administrative (e.g., clinics and schools) and household sample surveys. Each source has its own advantages and disadvantages: for example, administrative data often already exist, and can be

    The Holy Quran is a religious book of Muslims. In many verses of Quran, various foods are discussed. It seems that limited studies were performed on identification the nutritional verses and their frequencies in the Holy Quran. Therefore, the aims of present study were to establish a numerical model system for studying nutritional verses of Quran, determination of verses with nutritional concepts and frequency of foodstuffs in the Holy Quran. In this descriptive analytical study, "Ghamoos e Quran" and "Vazheyab" online softwares were used to determine the nutritional keywords in Quran. For searching, translating, and interpretation of verses, "Noor-e-Jami Tafasir version 2.1"; "Zekr" and "Pars Quran"softwares were applied. Sixty-four nutritional keywords and 257 nutritional verses were identified. Findings indicated that aliment/foods, eating, water/drinking words, and their derivatives are repeated 171, 109, and 131 times in the Holy Quran, respectively. According to the Holy Quran, except Haram foods (pork meat, wine, carrion meat, blood, and meat of animals not slaughtered properly in the Islamic manner), all foods are tayyeb (lawful). The Holy Quran contains many foodstuffs and verses with nutritional concepts and it recommends eating varied and balanced diet.

    The objective of this study was to characterize the effect of feed restriction and compensatory growth during re-alimentation on the functionality of the somatotropic axis. We blocked 60 bulls into one of two groups: 1) restricted feed allowance for 125 days (period 1) (RES, n = 30) followed by ad libitum feeding for 55 days (period 2) or 2) ad libitum access to feed throughout (ADLIB, n = 30). A growth hormone releasing hormone (GHRH) challenge was performed during each period. At the end of each period, 15 animals from each treatment were slaughtered and hepatic tissue collected. Hepatic expression of 13 genes of the somatotropic axis was measured by qRT-PCR. RES displayed a lower growth rate during period 1 (0.6 vs. 1.9 kg/day; P 0.05); however, resultant plasma IGF-1 was lower in period 1 and greater in period 2 in RES animals (P 0.05). Collectively, the results of this study are consistent with uncoupling of the somatotropic axis following feed restriction. However, there is no evidence from this study that the somatotropic axis per se is a significant contributor to compensatory growth. Copyright © 2015 the American Physiological Society.

After considering available data on origins and biological activities of all types of TFA, including conjugated fatty acids (CLA, it has been proposed a regulatory definition of these fatty acids which is the chemical one : « the trans fatty acids are all unsaturated fatty acids that contain at least one double bond in a trans configuration ». This definition includes the CLA and TFA of animal origin. Daily intakes of TFA (except CLA in France was found to be 3 g/d in adults, i.e. 1.3 % total energy intake (E %. The male children are the most exposed to high TFA intakes which culminate at 2.5 E % for the 95 th percentile of the 12-14 year-old male children. Consumption of usual foods (not including the consumption of synthetic CLA supplements leads to a rumenic acid daily intake inferior to 200 mg/d (0.08 E %. The contribution of TFA of animal origin is 60 % in adult (55 % for milk and dairy products and 55 % (44 % for male children, showing a higher consumption of TFA of technological origin in the form of bakery products in children than in adults. According to epidemiological data, TFA intakes (except CLA of 2 E % are associated to a 25 % increased risk of the coronary heard disease.

    With the aim of assessing the possible benefits of nutritional therapy , 140 patients were prospectively studied during radiotherapy of the head and neck (81%) and esophageal cancer (19%). Mean age was 56.0 (17-80), with 114 males and 26 females. Duration of both nutrition and radiotherapy was 78.0 {+-} 45 days. Tube feeding was the primary modality in 50.7% of the population, and oral regimens in the remaining 49.3%, but associations between the methods were also used. Enteral diets were supplied under the supervision of a specialized tem for home alimentation (PROSNED). Compliance to the program was 100% and a lymphocyte count diminished along this period (1933 {+-} 1033 vs 1265 {+-} 688, p.0.001). A subjective improvement was reported by 84% of the population, and total calorie intake, that was below 60% of estimated needs in 100% of the cases initially, significantly improved to just 40% inadequate at the end of the observations. Radiotherapy was associated with mucositis in 21% of the patients, taste changes in 79%, xerostomy in 81%, anorexia in 66% and odinophagia in 59%. In the individuals selected for enteral feeding, side effects were represented by technical problems (20%) and gastrointestinal disorders (13%). All patients completed the nutritional support program and there was no mortality in this series. It is conclude that: early nutritional support during radiotherapy was able to maintain or improve the nutritional status; tube feeding, alone or in combination with oral diets, was indicated whenever appropriate and contributed to fulfillment of the energy requirements; reduction of total lymphocytes could not be prevented by the mentioned therapy; complications of enteral alimentation were mild and affected a small proportion of the population; troubles induced by radiotherapy were as frequent as expected, and tended to disturb the intake of the food; the compliance of the therapeutic plan was excellent and can be attributed to the efforts of the

    Over the last 50 years, parenteral nutrition has been recognised as an invaluable and potentially lifesaving tool in the physician's arsenal in the management of patients with intestinal failure or inaccessibility; however, it may also be associated with a number of potentially life-threatening complications. A recent NCEPOD report (2010) identified a number of inadequacies in the overall provision and management of parenteral nutrition and recommendations were made with the aim of improving clinical practice in the future. This paper focuses on the practical aspects relating to parenteral nutrition for adults, including important concepts, such as patient selection, as well as general management. We also explore the various pitfalls and potential complications and how these may be minimised.

  12. Dental health and alimentation among the Quintana Roo Mayas: coastal and inland sites of the classic-postclassic periods.

    The goal of this study is to compare both dental and skeletal stress indicators of the Classic and Postclassic coastal and inland sites of the State of Quintana Roo, Mexico. The hypothesis is that coastal populations will show osteo and dental pathologies characteristic of a primarily marine food source combined with a diet of horticultural resources. This kind of alimentation provides people with less environmental stress and therefore a better health status. However, over time, in the Postclassic period, the health conditions deteriorated among both coastal and inland inhabitants, according to the hierarchization of the society, militarization, and commercial activities of all the coastal sites. The sample was drawn from 19 sites (196 individuals of both sexes) from the east coast of the Yucatan Peninsula, as well as from inland localities within the boundaries of Quintana Roo. Both dental and osteological stress indicators were analyzed, and crosstabs were applied for absolute and relative frequencies and their corresponding χ(2) and F Fisher analyses. The osteopathological index of the coastal and inland sites of the Classic period were compared over time between the Classic coastal inhabitants and the Postclassic coastal inhabitants so as to understand how life conditions changed over time. The Mantel-Haenszel odds ratio, with the crosstabs controlling for sex (males and females), was also carried out. There are low frequencies of dental pathologies and anemia present in both the coastal and inland populations of Quintana Roo in the Classic and Postclassic times. Only the presence of periostitis is highly common in both types of site, and this is the only indicator with significant differences. The dental pathologies, anemia and periostitis, in general, present a slight upward trend in both the coastal and inland populations over time. The coastal populations have fewer frequencies of the above than the inland sites whilst, in the Postclassic period, both the

Os resultados mostram que o novo ambiente competitivo, deflagrado pela desregulamentação setorial e pela abertura comercial, permitiu a intensificação da concorrência e restringiu o poder de mercado das maiores empresas. Os dois segmentos foram obrigados a seguir o processo de adequação às exigências do consumidor, como a melhoria da qualidade, o aumento da variedade e a redução nos preços dos produtos. Todo esse processo foi liderado pelas maiores empresas, que realizaram investimentos em tecnologia e em capacidade produtiva e aumentaram, gradualmente, suas participações no mercado. O resultado desses ajustamentos traduziu-se, portanto, em melhor desempenho econômico e em maior benefício para a sociedade.The present work aimed to evaluate the adjustments occurred in the food sector of biscuit and pastry in Brazil, from 1995 to 2001, using the Structure-Conduct-Performance model of the Industrial Organization theory. The results demonstrated that the new competitive environment, started by the non-regulation in the sector and by the commercial openness, allowed tougher competition and restrained the market power of the major industries. Both segments had to adjust themselves to the demands of the consumer in the market by improving the quality of their products, furnishing a wider variety and reducing their costs. The whole process was led by the major industries, which invested in technology and productive capacity and, continually, increased their participation in the market. Therefore, as a result of these adjustments, there has been an improvement in the economic performance and a greater benefit for society.

    Full Text Available Introduction : Les aliments malsains sont facilement accessibles dans les lieux publics au Canada, ce qui favorise les maladies chroniques liées au régime alimentaire, comme l’obésité. Cette réalité est préoccupante, car les établissements publics servent souvent une grande quantité d’aliments destinés à des groupes vulnérables, tels que les enfants et les personnes âgées. L’adoption de politiques sur l’approvisionnement en aliments sains, qui soutiennent l’achat, la distribution, la vente ou l’offre d’aliments plus sains, apparaît depuis peu comme une stratégie prometteuse pour contrer ce problème de santé publique, en rendant plus accessibles les aliments sains. De telles politiques n’ont cependant pas encore été adoptées à grande échelle au Canada, malgré les recommandations de nombreuses organisations canadiennes à vocation scientifique et du domaine de la santé. Méthodologie : Afin d’étayer la prise de mesures stratégiques qui favoriseront l’approvisionnement en aliments sains au Canada, nous avons, en premier lieu, réalisé une synthèse des données probantes en vue d’évaluer les répercussions des politiques sur l’approvisionnement en aliments du point de vue des résultats sur la santé, ainsi que des ventes, de la consommation et de l’offre d’aliments plus sains. En second lieu, nous avons tenu une conférence de consensus en septembre 2014. Cette conférence, qui a réuni des experts en recherche sur la santé publique et les politiques nutritionnelles, ainsi que des professionnels de la santé et des services alimentaires, a permis l’étude des données probantes, la mise en commun des expériences et l’élaboration d’un énoncé de consensus et de recommandations sur l’approvisionnement en aliments sains au Canada.

    In Part I we present a multidisciplinary analysis model for the prediction of functional connections between the design variables and the electromagnetical, electrical and thermal performances of a brushless permanent magnet motor. In this paper we have elaborated a design methodology for electrical motors supplied from a variable-frequency low-voltage source. The objective is to take into account the influence of the inverter's dynamics from the beginning of the design, for the same reasons as we do for electromechanical and thermal constraints. The procedure is based on a Sequential Quadratic Programming optimization method. Two techniques are used to take into account the influence of the inverter: the first one develops the performance analysis with the multidisciplinary model; the second one considers the inverter's current reference as a supplementary optimization variable for the control of the design. Optimization difficulties linked to the chopping of the converter are discuted in connection with a sensitivity analysis of the torque, with respect to the inverter's current reference; a method is proposed to enhance the performances of the algorithm. The method has been applied to the design of a permanent magnet brushless DC motor used in the propulsion system of an electrical scooter; evolution of the design with the complexity level of analysis model is evidenced. Dans une première partie nous avons développé un modèle d'analyse pluridisciplinaire qui établissait les dépendances fonctionnelles entre les variables de conception et les performances magnéto-électro-thermiques d'un moteur brushless à aimants permanents. Dans cet article nous décrivons une procédure de dimensionnement adaptée à la conception de la machine alimentée à fréquence variable sous faible tension. L'objectif est d'intégrer la dynamique du convertisseur électronique dès la phase initiale du dimensionnement, au même titre que les spécifications

    A sedentary lifestyle and increased consumption of energy dense food have become more common in many parts of the world. The aim of this study was to study long term effects on body composition after a four week intervention with fast food based hyper-alimentation and limited physical activity in young normal weight subjects. Eighteen subjects, mean age 26 (6.6) years, increased their energy intake with in average 70% and physical activity were not to exceed 5000 steps/day. Body composition was measured by Dual energy x-ray (DXA) at baseline, after the intervention and after 12 months. A matched control group was also included. ANOVA and Student's paired and unpaired t-test were used. During the intervention body weight increased with 6.4 (2.8) kg and DXA measurements showed increases of both fat free mass and fat mass. Six months after the intervention the subjects had lost most of the weight gain, - 4.7 (3.1) kg. Twelve months after the intervention body weight had increased with 1.5 (2.4) kg compared to baseline (p = 0.018). DXA measurements at 12 months showed unchanged fat free mass compared to baseline but higher fat mass, + 1.4 (1.9) kg (p = 0.01). After 2.5 years the increase of body weight was 3.1 (4.0) kg (p = 0.01) while there was no change in controls compared to baseline, + 0.1(2.5) kg (p = 0.88). One year after a short term intervention with increased fast food based hyper-alimentation there was an increase of fat mass but unchanged fat free mass. As the change of fat mass was larger than expected from prospective epidemiological studies and as there was no increase of body weight in controls it raises the issue whether there is a long-term effect to increase fat mass of a short period of hyper-alimentation.

  12. Nutrition between sustainability and quality.

    Fara, G M

    2015-01-01

    This lecture describes the complex interrelations existing between human nutrition, quality of aliments, their safety and the sustainability of the feeding habits adopted by the different cultures in the World. At present, a significant part of the developing World is still affected by insufficient availability of nutricious and safe food, and these difficulties are due more to political events as wars and less to natural events as famine. It is equally true that in the developed World, where abundance reigns and international trade grants a large variety of foods everywere, the existing health problems arise from the excess of nutrition, worsened by sedentarity, because the fatigue due to manual work has disappeared and people maintain their feeding habits; but such problems depend also on the diet composition, which in some countries is too rich in meat and animal fats. As a consequence, chronic degenerative pathologies and a progressive dependance of people in their third age are becoming more and more common. But this situation could be overturned by corrective interventions driven by good epidemiological knowledge, as teach us the great international institutions as UNO and WHO. The goal is not to expand without limits the production of food, but to better distribute it socially and geographically, to minimize losses and wastes and also to change those diets based on foods which consume too many natural resources and, therefore, do not respect sustainability. Sustainability can be measured under different aspects: ecology (use of water, energy and soil), economy and health protection. Accurate analyses and evaluations have brought to the conclusion that the least sustainable diets are those, quite popular in the Anglosaxon countries and northern and eastern Europe, rich in meat and animal fats, while those based on cereals, legumes and fish - like the Japanese and the Mediterranean diets - respect much more the environment, consume less resources and improve

    The stomach, small and large intestines, heart, lungs, bone and kidneys were removed from 48 Sato lung cancer-bearing rats used in the previous experiments and given 90 mg/kg of tegafur (FT-207) by single intravenous administration and tissue 5-FU and FT-207 concentrations were measured. FT-207 concentration in the alimentary canal was somewhat lower than the blood concentration, but both were lowered in parallel. 5-FU concentration in the stomach and large intestines showed virtually identical changes in both IVH and PO groups, but IVH group tended to have higher concentration. IVH group showed higher values than PO group anytime, particularly in the large intestines. A reduction of the side effects on the digestive system via intravenous alimentation was thought due to the elimination of mechanical stimulation via a cessation of oral feeding. 5-FU concentration in the bone was highest in PO group at six hours after administration and blood concentration changes were parallel, but there was virtually no change in IVH group. Maximum values were found one hour after administration and slowly declined thereafter; at 24 hrs the values were 0.059 +/- 0.013 microgram/g, relatively high compared to the PO group at 0.041 +/- 0.022 microgram/g. In the present study under intravenous alimentation, the concentration changes were slight in spite of 5-FU maximum concentration being lower than that by oral feeding and the long-term high concentration which was maintained; this is thought to be a disadvantageous action with regard to the bone marrow. FT-207 concentration in the kidney, heart and lungs was the same as that for the blood, with a gradual reduction in IVH group. 5-FU concentration was the same for the kidneys and IVH group quickly reached to the high levels compared to PO group with only slight changes thereafter. Effects of continuous water load might be involved but not clear.

    Full Text Available Nutritional education is a participatory process of knowledge acquisition concerning a healthy diet. The implementation of nutritional education in the public health care system is put into question based on a survey carried out with health professionals, and with users of one Basic Health Care Unit (UBS. The execution of nutritional education requires health professional specific knowledge in order to approach alimentary problems. The nutritionist is not duly involved in the public health care. Based on quantitative and qualitative methodologies, eight UBS health professionals were interviewed in order to verify their professional and personal experiences concerning nutritional education. There were 306 users interviewed, which is a representative sample of the population which is assisted by the UBS, in order to analyze the influence of such activity in their health. The interview results show that the professionals have some difficulty in approaching information concerning alimentation and that they believe there is some room for a nutritionist's participation in a multi-disciplinary team. Around 97% of the users believe that nutrition interferes in their life quality and 19.28% of them believe that nutrition problems are related to education. Nutritional education, as a structured program, does not exist. The mobilization of nutritionists in the exercise of their function and in meeting demands of health professionals and health care users is necessary.

    Decompensated cicatrices stricture of upper alimentary canal is a complex disease clinically presenting a high mechanical blocking and leads to expressed abnormality of homeostasis, which requires its pathogenetic correction of urgency evidence. The greatest difficulty is correct protein-energy malnutrition and water-electrolyte metabolism. Prior to the imposition of stoma for feeding should begin immediately with standard parenteral nutrition solutions. In a subsequent it is nessesary to resort more physiologecal tube alimentasion. As with esophageal postambustion stricture electrical activity of the stomach inhibiting and in essentially remains small bowel function, preference should be given to ways of enteral threpsology support. This can be used as a balanced composition in breeding (primary breeding should be 1: 2) and special blends for intraintestinal alimentation (close chyme on line carrying the major components). In the case of postambustion struck of outlet termination stomach department when identified violations of the underlying functions of the digestive canal division, rational come to gentle tactics of enteral alimentation using mixtures, completely similar in composition to himus. At stricture janitor ulcer genesis appropriate tactics is enteral correction, similar to that used in the event of postambustion strictures of the zones when bowel function is largely preserved.

Les rayonnements peuvent être utilisés pour atténuer les larves des parasites des animaux. Avec les parasites ayant ainsi perdu leur virulence, on prépare des vaccins animaux. Il s'agit en fait de la seule méthode actuellement connue de production de tels vaccins. Des indicateurs isotopiques sont utilisés pour étudier le mouvement et le métabolisme des substances nutritives chez les animaux d'élevage et sont particulièrement précieux pour l'étude des oligoéléments essentiels. L'avantage que seuls possèdent les indicateurs isotopiques de permettre la détection de quantités infimes de produits chimiques est la raison d'être d'un nouveau programme de recherches sur les résidus de pesticides nuisibles dans les aliments d'origine végétale et animale. L’effet stérilisant et germicide des rayonnements possède une valeur irremplaçable pour la prévention ou le retard de l'altération d'un grand nombre de denrées alimentaires. La conservation par irradiation peut, par exemple, être utilisée, même après emballage, pour les denrées périssables ne supportant ni la cuisson ni la congélation.

    Full Text Available Cette étude évalue l’impact de l’utilisation des sous-produits agroalimentaires dans l’alimentation des poissons d’élevage en Côte d’Ivoire. Une enquête a été réalisée en 2013 dans quinze principales zones piscicoles sur les caractéristiques technico-économiques des fermes, le profil socio-économique des promoteurs et les pratiques aquacoles, particulièrement l’alimentation des poissons. Les résultats révèlent que 71 % des pisciculteurs enquêtés utilisent des sous-produits agricoles durant au moins un stade de production. Parmi eux, 53 % utilisent exclusivement des sous-produits. Le son de riz (52 % et le mélange de sons de riz et de maïs (28 % sont les plus utilisés. Les prix moyens de ces sous-produits varient entre 20 et 105 FCFA/kg. Oreochromis niloticus et Heterotis niloticus sont les principales espèces élevées en polyculture sur les fermes. Les sous-produits sont utilisés en système semi-intensif, extensif et en rizipisciculture, en majorité en zone rurale. Les pisciculteurs sont pour la plupart des agriculteurs, âgés de plus de 40 ans. Les taux d’utilisation des sous-produits sont plus élevés dans les régions de l’Ouest, du Centre-Ouest et du Sud-Ouest de la Côte d’Ivoire, par rapport à celles du Sud et de l’Est. Les rendements des fermes sont relativement faibles (544 à 2445 kg/ha/an, avec des gains moyens quotidiens de 0,87 et 9,97 g/j pour le tilapia et l’heterotis respectivement. L’analyse des stratégies des acteurs suggère la nécessité de définir des mécanismes d’accompagnement et de financement de la pisciculture, afin que ces acteurs puissent améliorer les formulations alimentaires à partir des matières premières locales et accessibles.

    Enteral feeding provides physiologic, metabolic, safety, and cost benefits over parenteral nutrition. There are various ways enteral nutritional is administered and scheduled. The method of administration must be individualized to each patient's specific needs. Enteral nutrition is not only the supply of exogenous substrates and to prevent depletion of endogenous sources. Today the enteral nutrition becomes part of a therapeutic strategy to influence the severity of the disease to affect the function of GIT, and to modulate immune responses of the gut and the whole organism. Early enteral nutrition in the postoperative period reduces the risk of infectious complications. (author)

    2007-06-01

    This study aimed to investigate whether feed restriction and re-alimentation differently affect lipid content and activities of lipogenic or catabolic enzymes according to muscle types in pigs. At around 28 kg body mass (BW), sixty pigs (n=30 per group) were allocated to either ad libitum (AL) or restricted/re-feeding (RA) regimens. After feed restriction (80 kg BW), lipid content was reduced (P<0.01) in the oxidative rhomboideus (RH) as in the glycolytic biceps femoris (BF) muscles of RA pigs compared with AL pigs. Lower activities (P<0.05) of the lipogenic enzymes fatty acid synthase (FAS) and malic enzyme (ME) were observed in the RH but not in the BF of RA vs. AL pigs. After re-feeding (110 kg BW), lipid content was restored in the RH, but was still 12% lower (P<0.05) in the BF of RA compared with AL pigs. In the RH, the trend for an enhanced FAS activity and for a smaller weight-related decrease of ME activity in RA pigs than AL pigs during re-feeding, may have contributed to the muscle fat recovery observed in the RA pigs. In the BF, higher oxidative enzyme activities (P<0.10) in RA pigs compared to AL pigs might explain the incomplete lipid recovery observed after re-feeding in the former animals. In conclusion, metabolic activities in response to restriction and re-feeding differed according to muscle metabolic type.

    Full Text Available Nutritional support of surgical patients is a necessary part of the treatment. It alone cannot cure the disease but it significantly affects the recovery of patients and supports surgical interventions. Patients in malnutrition have shown to have significantly more postoperative infectious and non-infectious complications. This significantly prolongs treatment time and increases costs. However, there is one fact that cannot be expressed in money, which is the patient's impression of the surgical intervention. Adequate preoperative patient support, based on the intake of liquid nutritive solutions, reduces preoperative stress and deflects the metabolic response. Now, it is recommended for adults and children older than one year to drink clear liquid up to 2 hours before induction in anesthesia. Appropriate enteral nutrition has a significant place in the postoperative recovery of patients. Enteral nutrition is reducing complications, mainly infectious complications because the function of the digestive system as one large immune system is preserved. Perioperative enteral nutrition is a necessary part of the modern treatment of surgical patients. In addition to the significant effect on the occurrence of postoperative complications, it is also important that this type of diet improves the psychological status of patients.

    Full Text Available Les pesticides et plus généralement les composés organochlorés (PCB et dioxines ont été largement répandus dans l’environnement depuis la seconde guerre mondiale. Les progrès considérables des méthodes d’analyse et des connaissances moléculaires des mécanismes de toxicité ont été plus récents. Ainsi, la mise en évidence de traces de ces composés dans l’ensemble des compartiments de l’environnement et la découverte d’effets néfastes non pris en compte dans les premières utilisations nous amènent à ré-examiner le rapport risques/avantages. La multiplicité des mécanismes d’action des produits chimiques présentant des propriétés insecticides, herbicides et fongicides peut conduire à des effets toxiques sur des organismes « non cibles », y compris l’homme. Des études épidémiologiques ont été menées pour détecter des augmentations éventuelles d’effets cancérigènes et d’atteintes des fonctions neurologiques et reproductrices chez les populations exposées professionnellement (travailleurs de l’industrie chimiques, agriculteurs. Pour les consommateurs, les effets retardés d’exposition à de faibles doses sont difficiles à mettre en évidence.

    Full Text Available Le secteur appelé San Gabán/lnambari (district de San Gabán, province de Carabaya, Puno situé sur les derniers contreforts de la Cordillère Nevada de Carabaya, est peuplé par des immigrants des hauts plateaux - plus particulièrement des provinces de Melgar et de Carabaya mais aussi de quelques districts de la province d'Azangaro - qui y sont confrontés, en l'absence d'une voie de communication, avec des conditions particulières d'isolement géographique, culturel, économique et politique. Cette transplantation dans la forêt vierge - mouvement migratoire spontané - pose aux immigrants, qu'ils soient permanents ou temporaires, de nombreux problèmes d'adaptation, problèmes d'autant plus importants que les colons abordent les terres basses sans aucune préparation psychologique, éducative et technique. On examine ici le comportement et les réactions des individus dans le domaine de l'alimentation. La première partie de l'étude est consacrée aux composants de l'alimentation. Cette dernière repose avant tout sur les végétaux cultivés et plus particulièrement sur le riz, le manioc, le maïs, les « papas japonesas » et les bananes. Elle est irrégulièrement complétée par les produits de la basse-cour, par un peu de gibier et de poisson et par des denrées que les immigrants font venir ou rapportent de leur village d'origine à l'occasion de leurs voyages périodiques. Parmi ces denrées figurent surtout le chuño, la farine de chuño, la farine d'orge, la cañihua, le charqui, les pâtes, l'huile, le sucre et le sel. On ne peut manquer d'être frappé par le parallélisme existant entre les aliments adoptés et ceux dont l'immigrant se nourrissait dans son district d'origine. On remarque que la satisfaction des besoins alimentaires pose à l'individu un sérieux problème d'adaptation aux ressources locales. Cette adaptation est lente car l'immigrant adopte envers le milieu, semble-t-il, une attitude défensive. Sa m

    1995-03-01

    In switched reluctance motors fed by a constant voltage source (like a battery) at high frequencies, the current becomes unpredictable and often cannot reach a given reference value, because of the variation of the inductances with the rotor position ; the “motional” m.m.f. generates commutation troubles which increase with the frequency. An optimal control as well as an approximate design of the motor require a quick and simple calculation of currents, powers and losses ; now, in principle, the non-linear electrical equation needs a numerical resolution, whose results cannot be extrapolated. By linearizing this equation by intervals, the method proposed here allows to express analytically, in any case, the phase currents, the torque and the copper losses, when the feeding voltage itself is constant by intervals. The model neglects saturation, but a simple adjustment of the inductance (chosen ad libitum) allows to deal with it.

    Os rótulos presentes nas embalagens de alimentos industrializados devem apresentar várias informações, regulamentadas por órgãos oficiais, que contribuam com o consumidor na escolha adequada do produto do ponto de vista nutricional e indiquem a forma correta de conservação e preparo. Foram abordados trezentos consumidores no ato da compra, em supermercados varejistas e questionados através de formulário próprio para avaliação de seu comportamento com relação aos rótulos, considerando os seguintes pontos: freqüência de leitura, principal informação observada, critérios utilizados na compra, utilização da informação nutricional no dia a dia e consumo de alimentos de procedência transgênica. A confiabilidade dos consumidores foi relacionada com a leitura do rótulo, com possíveis alterações do produto e com problemas de saúde influenciando na decisão de compra. Os dados foram tratados utilizando o programa estatístico "SPSS for Windows versão 11.00", no qual foram realizadas distribuições de freqüências e analisadas pelo teste Qui-quadrado. Observou-se que, apesar do consumidor consultar com freqüência o rótulo dos produtos alimentícios na busca de informações, ainda existe a necessidade de campanhas educativas sobre o uso apropriado das informações contidas no rótulo de forma que este possa contribuir na escolha dos alimentos pelos consumidores.

    Full Text Available No atual mercado competitivo, conhecer a rentabilidade dos produtos oferecidos é peça chave para o sucesso de uma empresa. Porém, para chegar neste percentual é preciso seguir alguns procedimentos. De acordo com este contexto, a pesquisa efetuada tem o objetivo de evidenciar os procedimentos a serem seguidos para determinação e análise da rentabilidade dos produtos em micro e pequenas empresas alimentícias e, para alcançar este objetivo, o estudo mostra inicialmente um levantamento do referencial teórico relacionado ao tema. A pesquisa é de tipologia exploratória, onde foi feito um estudo de caso buscando analisar a rentabilidade dos produtos da empresa estudada e também identificar a viabilidade ou não da empresa tornar-se formal. O levantamento dos dados foi feito um acompanhamento de todo processo produtivo dos produtos estudados. Com o estudo conclui-se que micro e pequenas empresas têm papel fundamental na economia brasileira e mundial, porém estas precisam estar preparadas para sobreviver às dificuldades do mercado. Diante disso, o estudo efetuado mostrou que na atual situação o empreendimento possui boa rentabilidade de seus produtos e ao tornar-se formal, a melhor opção, no atual momento, é o enquadramento como Empreendedor Individual. A opção do Simples Nacional se torna favorável somente após aumento de faturamento, pois com a formalização a empresa passa a ter algumas despesas fixas que então não existiam.

    The effects of combined nutritional support (parenteral, enteral, and oral) were measured in cancer patients unable to maintain normal alimentation.Changes in body composition were quantified by measurement of total body levels of nitrogen, potassium, water, and fat. The protein-calorie intake of the patients was also evaluated by dietary survey (4-day recall). Standard anthropometric and biochemical measurements for nutritional assessment were obtained for comparison. The dietary evaluation indicated that the dietary supplementation for all patients was more than adequate to meet their energy requirements. Determination of body composition indicated that change in body weight was equal to the sum of the changes in body protein, total body water, and total body fat. Information on the nature of the tissue gained was obtained by comparison of body composition data with the ratio of protein:water:lean body mass for normal tissue. The mean gain of protein in the cancer patients was quite small (0.3-0.6 kg). The main change in body weight appeared to be the result of gains in body water and body fat. The total body nitrogen to potassium ratio served to define the extent of tissue anabolism following hyperalimentation. The ratio dropped in the cancer patients following hyperalimentation toward the value of the control subjects on ad libitum diets. Total body nitrogen was determined by prompt gamma neutron activation analysis, total body potassium by whole-body counting

    2000-06-01

    Prevention of unintended adolescent pregnancy is a primary goal of the American Academy of Pediatrics and of many health providers. Nevertheless, many adolescents become pregnant every year in America. Pediatricians therefore should be aware of nutritional recommendations for pregnant adolescents to provide optimal care. The importance of nutrition during pregnancy is here reviewed from a pediatric perspective. Pregnancy, particularly during adolescence, is a time of extreme nutritional risk. The adolescents most likely to become pregnant are often those with inadequate nutritional status and unfavorable socio-economic background. There is increasing evidence of competition for nutrients between the growing pregnant adolescent and her fetus. Also, the prenatal environment has been implicated in the development of obesity, cardiovascular disease, and diabetes in both the mother and her offspring. Many adolescents have poor diet quality and poor knowledge of appropriate nutrition; these habits may not change during pregnancy. Current knowledge and recommendations regarding the intake of energy, calcium, and folate are discussed in detail.

    Modular Enteral Nutrition may be a substitute for Parenteral Nutrition in children with different pathologies. Study of 4 children with different pathologies selected from a group of 40 admitted to the Maternal-Childrens Hospital "Valle de Hebrón" in Barcelona, who received modular enteral nutrition. They were monitored on a daily basis by the Dietician Service. Modular enteral nutrition consists of modules of proteins, peptides, lipids, glucids and mineral salts-vitamins. 1.--Craneo-encephalic traumatisms with loss of consciousness, Feeding with a combination of parenteral nutrition and modular enteral nutrition for 7 days. In view of the tolerance and good results of the modular enteral nutrition, the parenteral nutrition was suspended and modular enteral nutrition alone used up to a total of 43 days. 2.--55% burns with 36 days of hyperproteic modular enteral nutrition together with normal feeding. A more rapid recovery was achieved with an increase in total proteins and albumin. 3.--Persistent diarrhoea with 31 days of modular enteral nutrition, 5 days on parenteral nutrition alone and 8 days on combined parenteral nutrition and modular enteral nutrition. In view of the tolerance and good results of the modular enteral nutrition, the parenteral nutrition was suspended. 4.--Mucoviscidosis with a total of 19 days on modular enteral nutrition, 12 of which were exclusively on modular enteral nutrition and 7 as a night supplement to normal feeding. We administered proteic intakes of up to 20% of the total calorific intake and in concentrations of up to 1.2 calories/ml of the final preparation, always with a good tolerance. Modular enteral nutrition can and should be used as a substitute for parenteral nutrition in children with different pathologies, thus preventing the complications inherent in parenteral nutrition.

  18. Nutrition and fertility.

    Pinelli, G; Tagliabue, A

    2007-12-01

    The first studies about fertility and nutrition date back to the 70ies and already showed a strict relation among female fertility, weight and body composition. However, the mechanisms of this connection started to be explained only after leptin's discovery. According to some authors' opinion, leptin could interact with reproductive axis at multiple sites with stimulatory effects at the hypothalamus and pituitary and stimulatory or inhibitory actions at the gonads. Leptin could play a role in other physiologic processes such as menstruation and pregnancy, and could initiate the complex process of puberty. It has been showed that conditions in which nutritional status is suboptimal, such as eating disorders, exercise induced amenhorrea, functional hypothalamic amenhorrea and polycystic ovarian syndrome, are associated with abnormal leptin levels. These conditions, are characterized by severe changes in body composition and dietary habits. Since leptin is regulated by body composition and dietary factors, (such as energy intake and macronutrient composition), a strict connection between nutritional intake and fertility regulated by leptin is confirmed. This review focuses on the current knowledge about nutritional factors that influence leptin levels. Since clinical and subclinical nutritional imbalance can determine the development and the maintenance of neuroendocrine and metabolic aberrations, studies on fertility need a deeper attention about dietary habits and nutritional status.

Comment ce critère intervient-il dans le choix de variétés de pain et de pomme, couramment consommées en France, leur appréciation et leur consommation ? Une étude a été menée auprès d’enfants de la région parisienne, 162 pour le pain, 132 pour la pomme, garçons et filles de 6 à 12 ans. Ils ont participé à un test de dégustation (perception et appréciation de deux sortes de pain, baguette et pain de seigle, ou de deux variétés de pomme, Granny Smith et Red Chief, et ils ont répondu à un questionnaire portant sur leur consommation de pains ou de pommes et sur diverses attitudes sensorielles. Les réponses obtenues ont été homogènes, ne variant pas en fonction de l’âge et du sexe. Les enfants se reconnaissent sensibles à la sonorité croquante du pain ou des pommes. Ils disent que l’aspect croquant fait partie des critères d’appréciation des pains ou des pommes, au même titre que d’autres critères, la couleur, la forme, la prise en main, le goût et l’odeur mais ils ne le situent pas tout à fait au même rang, ce qui témoigne de la particularité sensorielle de chacun de ces aliments. L’aspect croquant pourrait participer à l’évaluation de l’appréciation globale d’un morceau de pain, lors de cette dégustation au moins, alors qu’il ne semble pas intervenir pour l’appréciation des pommes dont les saveurs légèrement sucré ou acide sont immédiatement reconnues.

    India has achieved self-sufficiency in the production of food grains, yet the production of milk, legumes, vegetables, oils and fats, eggs, and meat is far short of the needs of the population. The Indian diet predominantly comprises cereals, and the diets of expectant and nursing mothers as well as children are grossly deficient in protective foods. Serious nutritional inadequacies have resulted in low birth weight, retarded growth, and nutritional deficiencies (protein energy malnutrition in preschool children, vitamin A deficiency, iron deficiency in women of reproductive age, and iodine deficiency disorders among neonates and schoolchildren). General malnutrition is prevalent in 25% of the rural and 20% of the urban population. Deficiency symptoms of vitamin B complex and vitamin C are also not uncommon. 37% of the population of India lives below the poverty limit, the literacy rate is only 52.1% (39.4% for women), safe drinking water is scarce, nutritional ignorance is rampant, there is a lack of personal hygiene, and poor sanitation all account for malnutrition. A number of government and nongovernmental organizations' programs have attempted to raise the level of nutrition and the standard of living of the people. Some of them include the integrated child development services, special nutritional program, national vitamin A deficiency prophylaxis program, national anemia prophylaxis program, national goiter control program, midday meal program, special class feeding programs, universal immunization program, nutritional and health education through the mass media as well as the observance of world food day and world health day. The national health policy gives high priority to the promotion of family planning, the provision of primary health care, and the acceleration of welfare programs for women and children.

The EPaNIC study shows an advantage in terms of discharges alive from the ICU when parenteral nutrition is delayed to day 8 as compared with combining enteral nutrition and parenteral nutrition from day 3 of ICU stay. The difference between the guidelines from the European Society of Enteral and Parenteral Nutrition in Europe and American Society for Parenteral and Enteral Nutrition/Society of Critical Care Medicine in North America concerning the combination of enteral nutrition and parenteral nutrition during the initial week of ICU stay was reviewed. The EPaNIC study clearly demonstrates that early parenteral nutrition in the ICU is not in the best interests of most patients. Exactly at what time point the combination of enteral nutrition and parenteral nutrition should be considered is still an open question.

  3. Nutrition and pubertal development

    Full Text Available Nutrition is one of the most important factors affecting pubertal development. Puberty entails a progressive nonlinear process starting from prepubescent to full sexual maturity through the interaction and cooperation of biological, physical, and psychological changes. Consuming an adequate and balanced healthy diet during all phases of growth (infancy, childhood and puberty appears necessary both for proper growth and normal pubertal development. Girls begin puberty at an earlier age compared to past decades. Excessive eating of many processed, high-fat foods, may be the cause of this phenomenon. Overweight or obese children are more likely to enter puberty early. Some evidence suggests that obesity can accelerate the onset of puberty in girls and may delay the onset of puberty in boys. Moreover, the progression of puberty is affected by nutrition. On the other hand, puberty triggers a growth spurt, which increases nutritional needs including macro and micronutrients. Increased caloric, protein, iron, calcium, zinc and folate needs have to be provided during this critical period of rapid growth. Severe primary or secondary malnutrition also can delay the onset and progression of puberty. The higher incidence of anorexia nervosa and bulimia in adolescents imposes a nutritional risk on pubertal development. Moreover, many environmental endocrine disruptors (EDs have been identified that can significantly impair the normal course of puberty. This mini-review sums up some important findings in this important complex that link nutrition and pubertal development.

    Bouldering competitions are held up to International level and governed by the International Federation of Sport Climbing. Bouldering has been selected to feature at the 2020 Olympic Games in Tokyo, however, physiological qualities and nutritional requirements to optimize performance remain inadequately defined due to large gaps in the literature. The primary goals of training include optimizing the capacity of the anaerobic energy systems and developing sport-specific strength, with emphasis on the isometric function of the forearm flexors responsible for grip. Bouldering athletes typically possess a lean physique, similar to the characteristics of sport climbers with reported body fat values of 6-12%. Athletes strive for a low body weight to improve power to weight ratio and limit the load on the extremities. Specialized nutritional support is uncommon and poor nutritional practices such as chronic carbohydrate restriction are prevalent, compromising the health of the athletes. The high intensity nature of bouldering demands a focus on adequate carbohydrate availability. Protein intake and timing should be structured to maximize muscle protein synthesis and recovery, with the literature suggesting 0.25-0.3 g/kg in 3-4 hr intervals. Supplementing with creatine and b-alanine may provide some benefit by augmenting the capacity of the anaerobic systems. Boulderers are encouraged to seek advice from nutrition experts to enhance performance, particularly important when weight loss is the desired outcome. Further research is warranted across all nutritional aspects of bouldering which is summarized in this review.

    The topic "nutrition and the eye" cannot adequately be covered in a single review article; indeed, dozens of books and hundreds of articles have been written on the subject. This review concentrates on three areas in which specific nutrients are known or theorized to have a major impact on vision and the visual system: vitamin A deficiency; antioxidants and their proposed role in the prevention of age-related cataract and macular degeneration; and nutritional optic neuropathies, including those of the recent Cuban epidemic. In addition, this article touches on nutritional treatments that have been suggested for several less common eye diseases and, finally, considers several less prevalent conditions in which deficiency of or excess exposure to a particular nutrient has been associated with ocular pathology.

    Nutrition has long been associated with skin health, including all of its possible aspects from beauty to its integrity and even the aging process. Multiple pathways within skin biology are associated with the onset and clinical course of various common skin diseases, such as acne, atopic dermatitis, aging, or even photoprotection. These conditions have been shown to be critically affected by nutritional patterns and dietary interventions where well-documented studies have demonstrated beneficial effects of essential nutrients on impaired skin structural and functional integrity and have restored skin appearance and health. Although the subject could be vast, the intention of this review is to provide the most relevant and the most well-documented information on the role of nutrition in common skin conditions and its impact on skin biology.

    Full Text Available Nutrition is one of the fundamental factors that influence the effectiveness of physical activity, increase efficiency and replenishment of muscle mass, balances the ratio of energy consumed and restored. The diet of an athlete can and should be built on common foods available and prepared in accordance with generally accepted principles of healthy eating. The need for major macronutrients and micronutrients is determined by the need for energy, the intensity of sweating and the goals for building muscle mass. Depending on the intensity of the proposed load including competition, there are individual nutritional needs and, if necessary, various food supplements may be used. The basic principles of sport nutrition are described in this article

    Medical nutrition therapy (MNT) is a key component of diabetes management. The importance of balancing macronutrients, reducing carbohydrate load, lowering glycemic index, and implementing an overall healthy dietary pattern are emerging as better approaches for MNT in diabetes. Recent research points to improved glycemic control, reduction in body weight, and improvement in many cardiovascular risk factors when these approaches are provided by registered dietitians or health care providers. This review article discusses the current evidence about the role of sensible nutrition in diabetes management. Specific eating plans for weight reduction and for patients with type 1 diabetes are also discussed. Copyright © 2016 Elsevier Inc. All rights reserved.

    Psittacine birds eat plant-based foods. Birds in the wild seem to be able to balance their energy needs, amino acids, and calcium. Companion birds in captivity do not do as well when self-selecting, and balanced diets are needed to improve their general health. A nutritional history is important to determine whether the avian patient is in balance nutritionally. Understanding the various sources of the fat-soluble vitamins, calcium, and protein will help guide clients to provide nutritious foods for their birds. Owners need to learn to use foraging as a major source of their bird's diet and techniques. Copyright © 2014 Elsevier Inc. All rights reserved.

    A comparative study of both the evolution of strontium-90 content in the bones of individuals of different ages for the period 1962-1967 as related to calcium, and the corresponding diets allowed to establish the relationship between food contribution and the resulting bone burden. The study is mainly devoted to the group of adults for which a mathematical expression is proposed which allows for the exchangeable form of a skeletal calcium fraction turned over in less than a year from the dietary calcium, and the stabilized form constituting the larger part of bone tissue characterized by a slow turnover. Both the amount of the exchangeable fraction and the turnover rate of the stabilized fraction are determined for vertebrae and ribs. At birth, bone levels indicate that the calcium used for skeleton modelling during foetal life originates from both maternal diet and bone tissue and a value is given, to their relative significance. There appears a good relationship between bone levels in infants from 6 months to 1 year of age and their diets. The physiological parameters particular to this age are quantified. (authors.

    Full Text Available The development of IgE-mediated allergic diseases is influenced by many factors, including genetic and environmental factors such as pollution and farming, but also by nutrition. In the last decade, substantial progress has been made in our understanding of the impact that nutrition can have on allergic diseases. Many studies have addressed the effect of breastfeeding, pre-, pro- and synbiotics, vitamins and minerals, fiber, fruit and vegetables, cow’s milk, and n-3 fatty acids, on the development of allergies. In addition, nutrition can also have indirect effects on allergic sensitization. This includes the diet of pregnant and breastfeeding women, which influences intrauterine development, as well as breastmilk composition. These include the diet of pregnant and breastfeeding women that influences intrauterine development as well as breastmilk composition, effects of food processing that may enhance allergenicity of foods, and effects via modulation of the intestinal microbiota and their metabolites. This editorial review provides a brief overview of recent developments related to nutrition and the development and management of allergic diseases.

    2014-09-01

    Grocery stores represent a context in which a majority of people's food purchases occur. Considering the nutrition quality of the population's food intake has dramatically decreased, understanding how to improve food choice in the grocery store is paramount to healthier living. In this work, we detail the type of financial resources from which shoppers could draw (i.e., personal income and benefits from government food assistance programs to low income populations) and explain how these financial resources are allocated in the grocery store (i.e., planned, unplanned, error). Subsequently, we identify a conceptual framework for shopper marketing nutrition interventions that targets unplanned fruit and vegetable purchases (i.e., slack, or willingness to spend minus list items). Targeting slack for fresh fruit and vegetable purchases allows retailers to benefit economically (i.e., fruit and vegetables are higher margin) and allows shoppers to improve their nutrition without increasing their budgets (i.e., budget neutrality). We also provide preliminary evidence of what in-store marketing of fresh fruits and vegetables could entail by modifying grocery carts and grocery floors to provide information of what is common, normal, or appropriate fruit and vegetable purchases. In each example, fresh fruit and vegetable purchases increased and evidence suggested shopper budget neutrality. To provide context for these results, we detail measurement tools that can be used to measure shopper behaviors, purchases, and consumption patterns. Finally, we address theoretical, practical, and policy implications of shopper marketing nutrition interventions. Copyright © 2014 Elsevier Inc. All rights reserved.

    2005-06-01

    Although it is considered that metabolic and nutritional support must be part of the management of septic patients, it has not been conclusively shown that nutritional support will improve survival or complications from sepsis. Specific data on this issue are scarce since there are few studies that have investigated specialized nutritional support in septic patients. Thus, most of the recommendations are based on outcomes obtained in severely ill patients with different pathologies. It is assumed that nutritional support should be carried out through the enteral route whenever possible, as in other critically ill patients. The energetic waste in these patients is highly variable, although in general terms the hypermetabolic situation may be classified as moderate. An adjustment factor of 1.25-1.30 is recommended for the Harris-Benedict's equation to calculate the caloric intake. Septic patients should receive a hyperproteic intake. The amount of glucose administered should not exceed 70% of non-protein calories, and lipids intake should not exceed 40%. With regards to micronutrients, it is recommended to increase the supply of those with antioxidant properties (vitamin E, carotenes, vitamin C, selenium). There are data to consider that the use of diets enriched with pharmaco-nutrients (both with parenteral and enteral routes) may be beneficial in septic patients, although there is some controversy when interpreting the outcomes.

  15. Tuberculosis and nutrition

    Directory of Open Access Journals (Sweden)

    Gupta Krishna

    2009-01-01

    Full Text Available Malnutrition and tuberculosis are both problems of considerable magnitude in most of the underdeveloped regions of the world. These two problems tend to interact with each other. Tuberculosis mortality rates in different economic groups in a community tend to vary inversely with their economic levels. Similarly, nutritional status is significantly lower in patients with active tuberculosis compared with healthy controls. Malnutrition can lead to secondary immunodeficiency that increases the host′s susceptibility to infection. In patients with tuberculosis, it leads to reduction in appetite, nutrient malabsorption, micronutrient malabsorption, and altered metabolism leading to wasting. Both, protein-energy malnutrition and micronutrients deficiencies increase the risk of tuberculosis. It has been found that malnourished tuberculosis patients have delayed recovery and higher mortality rates than well-nourished patients. Nutritional status of patients improves during tuberculosis chemotherapy. High prevalence of human immunodeficiency (HIV infection in the underdeveloped countries further aggravates the problem of malnutrition and tuberculosis. Effect of malnutrition on childhood tuberculosis and tuberculin skin test are other important considerations. Nutritional supplementation may represent a novel approach for fast recovery in tuberculosis patients. In addition, raising nutritional status of population may prove to be an effective measure to control tuberculosis in underdeveloped areas of world.

  2. Nutrition and Liver Health.

    Science.gov (United States)

    Jackson, Alan A

    2017-01-01

    Good clinical practice is based on a secure and accurate diagnosis. Poor nutrition is frequently associated with disorders of the liver, and a specific nutrition diagnosis is needed for providing best care and experiencing successful outcome. There is opportunity for better-structured approaches to making secure and consistent nutritional diagnoses in patients with liver disease. Nutrition is the set of integrated processes by which cells, tissues, organs and the whole body acquire the energy and nutrients to retain normal structure and perform the required functions. At the level of the whole body, this is achieved through dietary supply and the capacity of the body to transform the substrates and cofactors necessary for metabolism. All of these domains (diet, metabolic capacity, activity of the microbiome, body composition and the level of demand for energy and nutrients) are influenced by levels of physical activity and can vary according to physiological and pathological disease states. The liver plays a central role in establishing and maintaining these regulated processes. Its capacity to achieve and maintain these functional capabilities is established during one's early life. When these capabilities are exceeded and the ability to maintain the milieu interieur is compromised, ill-health supervenes. Stress tests that assess flow through gateway pathways can be used to determine the maximal capacity and functional reserve for critical functions. The inability of the liver to reliably integrate body lipid metabolism and the accumulation of abnormal lipid are obvious manifestations of impaired regulation both in situations of weight loss, for example, the fatty liver of severe malnutrition, and in situations of energy excess, as in non-alcoholic fatty liver disease. The use of stable isotopic probes and the more recent definition of the variability in the metabolome in different nutritional and pathological states indicate the great potential for clinical tools

    2013-12-01

    The incidence of malnutrition in hospitalized patients is relatively high (up to 55%) despite breakthroughs in nutrition support therapies. These patients have increased morbidity and mortality, extended hospital stays, and care that is associated with higher costs. These patients are often poorly managed due to inadequate nutrition assessment and poor medical knowledge and practice in the field of nutrition. Nutrition support teams (NSTs) are interdisciplinary support teams with specialty training in nutrition that are often comprised of physicians, dietitians, nurses, and pharmacists. Their role includes nutrition assessment, determination of nutrition needs, recommendations for appropriate nutrition therapy, and management of nutrition support therapy. Studies have demonstrated significant improvements in patient nutrition status and improved clinical outcomes as well as reductions in costs when patients were appropriately managed by a multispecialty NST vs individual caregivers. Despite this, there has been steady decline in the number of formal NST in recent years (65% of hospitals in 1995 to 42% in 2008) as hospitals and other healthcare organizations look for ways to cut costs. Given the importance of nutrition status on clinical outcomes and overall healthcare costs, a number of institutions have introduced and sustained strong nutrition training and support programs and teams, demonstrating both clinical and economic benefit. The benefits of NST, training and implementation strategies, and tips for justifying these clinically and economically beneficial groups to healthcare organizations and governing bodies are discussed in this review.

Projects also offered training in a variety of areas including management of plots, labor-saving technology--diesel-driven grinding mills, rice husking, machines, wells with hand pumps, motor pumps for irrigation, all geared towards women benefitting themselves by growing their own food and furthering their children's health and development. Projects such as the one in Senegal were undertaken in other regions of Africa, like the Sahel and the Wadis--low-lying areas. From these projects, aid agencies and governments have suggested a number of recommendations in seeking a solution to Africa's nutritional problems. 1st, a balance between production of cash crops and food for consumption is called for. 2nd, research is necessary to improve the quality of locally grown food as much as livestock. 3rd, governments should extend surface area cultivation, 4th, more research on the advantage of indigenous food plants, 5th, women should be in on all levels of decision making in food production, 6th, governments should increase women farmer's efficiency, and further women's access to land and credit and 7th, women should be provided with increased educational opportunities. Nutrition in developing countries cannot be viewed as an isolated phenomenon--solutions to nutritional development should include all aspects of the problem including health and nutrition education, growth monitoring, water supply, literacy, technological know-how, and agricultural and plant and soil conservation.

    The aim of the study was to determine and compare the endogenous ileal excretions of nitrogen and amino acids under protein-free and peptide alimentation by the dog and rat. Two diets were prepared, one that was devoid of protein and the other containing 23% enzyme hydrolysed casein. Chromic oxide was included in the diets as an indigestible marker. A total of 10 mixed breed dogs were fed hourly either a protein-free or enzymatically hydrolysed casein diet for a total of 10 days. A faecal sample was obtained from each dog on day 9 while digesta was obtained from the terminal 20 cm of the ileum directly after euthanasia on day 10. A total of 12 8-week-old Sprague-Dawley rats received the same diets as the dogs. A faecal sample from each rat was obtained on day 7 while ileal digesta samples were obtained on day 8. The endogenous ileal excretions of most amino acids were greater in the dogs and rats that received the enzymatically hydrolysed casein diet compared with those receiving the protein free diet. Whereas the pattern of endogenous amino acid excretion was similar in the rats and dogs, the dogs excreted a significantly greater amount of nitrogen (1.91 vs. 2.27 and 1.63 vs. 4.12 g/kg dry matter intake for the protein-free and peptide alimentation method, respectively) and all amino acids except for glycine, isoleucine and leucine. Endogenous ileal amino acid excretions are higher in dogs compared to omnivorous animals such as rats and pigs but similar to the carnivorous cat.

    Full Text Available Le processus d’intensification des élevages, entamé dans les années 1970, s’est accompagné d’un développement croissant du recours aux aliments dits « composés », fabriqués à partir de différentes matières premières pour la plupart d’origine végétale. Les pratiques de la formulation des fabricants d’aliments composés, fondées sur une très forte substituabilité des matières premières, génèrent une concurrence très forte entre ces commodités. Dans un tel contexte de marché, la valorisation de certaines espèces repose sur des mécanismes permettant de contourner ou de s’affranchir de cette concurrence, mais dont l’efficacité reste fortement dépendante de l’organisation des acteurs au sein des filières. À partir de la comparaison des filières pois et lin, nous montrons ainsi qu’au-delà de la reconnaissance de propriétés nutritionnelles spécifiques pouvant valoriser différemment certaines espèces, la coordination des acteurs le long d’une filière est déterminante dans la diffusion des incitations économiques et informationnelles nécessaires à une orientation des agriculteurs en faveur d’espèces de diversification d’intérêt agro-écologique.

    Despite so many advantages of natural feeding, according to the research led in Poland between 2000 and 2005, in the sixth month of life only 8% of infants were strictly breast-fed. The aim of the study was to analyze the factors which have the influence on choosing the way of feeding of children hospitalized in the Department of Pediatric Propedeutics and Bone Metabolism Diseases. The inquiry was established among parents of newborns and infants up to 1 year old, hospitalized in the Department of Pediatric Propedeutics and Bone Metabolism Diseases between January and May 2008. The research was led on the group of 93 children (39 newborns and 54 infants). The inquiry consists of questions about the cause and duration of hospitalization, perinatal interview, ways of nourishment and parents' personal data. At the time of leading the inquiry 27 children (29%) were fed strictly naturally, 36 (38.7%) were bottle-fed, 23 (24.73%) were fed in the mixed way, 6 (6.5%) were fed by the stomach tube and 1 child (1.1%) was fed parenterally. 44.1% of parents obtained information about breast-feeding from media, whereas only 3 (3.2%) got it from medical staff. The most common reason for giving up breast feeding was the lack (or too little amounts) of mother's milk. The doctor appeared to be the main person who decided to introduce formula-feeding. Among children naturally-fed 21 (77.8%) were given formula in the first twenty-four hours after the labour. The factors which appeared to influence the choice of the way of alimentation, in statistically important way (p alimentation. The health care system (perinatal, labour and basic care) concerning mother and child, doesn't promote natural feeding.

    Full Text Available Cet article étudie la façon dont les gens ordinaires parlent de la nourriture et en particulier dans quelle mesure, et comment, ces discussions incluent des arguments sur l’environnement et les produits bios. Contrairement à de nombreuses études qui démontrent la préoccupation du public concernant les aliments et leur production, l’étude rapportée ici montre que, dans un cadre exploratoire où des danois étaient invités à discuter d’alimentation et de production alimentaire, les arguments environnementaux jouent un rôle insignifiant. Ceci peut être expliqué d’une part par l’émergence d’un nouveau discours sociétal qui minimise l’importance des problèmes environnementaux et, d’autre part, comme l’effet d’une tendance actuelle où les individus sont de plus en plus préoccupés par leur bien-être personnel.This paper addresses the way ordinary people talk about the food they eat and in particular to what extent, and how, such discussions include arguments about the environment and organic products. In contrast with the numerous studies demonstrating public concern over food and food production, the study reported here shows that in an exploratory set-up, where Danes were invited to discuss food and food production, environmental arguments played an insignificant role. This can be explained in part by the emergence of a new societal discourse that downsizes the importance of environmental problems, and in part as an effect of an ongoing trend in which individuals increasingly are concerned about their personal well-being.

  18. Nutrition for Space Exploration

    Nutrition has proven to be critical throughout the history of human exploration, on both land and water. The importance of nutrition during long-duration space exploration is no different. Maintaining optimal nutritional status is critical for all bodily systems, especially in light of the fact that that many are also affected by space flight itself. Major systems of concern are bone, muscle, the cardiovascular system, the immune system, protection against radiation damage, and others. The task ahead includes defining the nutritional requirements for space travelers, ensuring adequacy of the food system, and assessing crew nutritional status before, during, and after flight. Accomplishing these tasks will provide significant contributions to ensuring crew health on long-duration missions. In addition, development and testing of nutritional countermeasures to effects of space flight is required, and assessment of the impact of other countermeasures (such as exercise and pharmaceuticals) on nutrition is also critical for maintaining overall crew health. Vitamin D stores of crew members are routinely low after long-duration space flight. This occurs even when crew members take vitamin D supplements, suggesting that vitamin D metabolism may be altered during space flight. Vitamin D is essential for efficient absorption of calcium, and has numerous other benefits for other tissues with vitamin D receptors. Protein is a macronutrient that requires additional study to define the optimal intake for space travelers. Administration of protein to bed rest subjects can effectively mitigate muscle loss associated with disuse, but too much or too little protein can also have negative effects on bone. In another bed rest study, we found that the ratio of protein to potassium was correlated with the level of bone resorption: the higher the ratio, the more bone resorption. These relationships warrant further study to optimize the beneficial effect of protein on both bone and muscle

  19. Improving nutrition through nuclear science

    International Nuclear Information System (INIS)

    2003-06-01

    Good nutrition is essential to health and quality of life. As a United Nations agency dedicated to helping Member States achieve their social and economic goals, the International Atomic Energy Agency (IAEA) recognizes the importance of good nutrition and is working to address the problems underlying poor nutrition. In fact, many Agency activities serve basic human needs, by applying nuclear science to increase food production, improve health care, improve management of water resources, and assess sources of environmental pollution. Global progress in reducing malnutrition throughout the human life cycle has been slow and patchy. In its 2000 Report on the World Nutrition Situation, the United Nations Sub Committee on Nutrition estimated that in developing countries 182 million children under five years of age are chronically undernourished and 150 million are underweight. An estimated 30 million infants are born each year with impaired growth due to poor nutrition during pregnancy. Worldwide, renewed international commitments have been made to address this situation, and the IAEA is a vital partner in these efforts. Nuclear science provides valuable tools for monitoring factors that influence nutrition, such as micronutrients, body composition, and breast milk uptake. Through its sub-programme on nutrition, the Agency is helping countries to use isotope applications and other nuclear techniques to their nutritional problems and is supporting leading-edge research on the interaction between nutrition and environmental pollution and infection with the ultimate goal of improving human nutrition

    In contrast to the spectacular advances in the first half of the twentieth century with micronutrient-related diseases, human nutrition science has failed to stem the more recent rise of obesity and associated cardiometabolic disease (OACD). This failure has triggered debate on the problems and limitations of the field and what change is needed to address these. We briefly review the two broad historical phases of human nutrition science and then provide an overview of the main problems that have been implicated in the poor progress of the field with solving OACD. We next introduce the field of nutritional ecology and show how its ecological-evolutionary foundations can enrich human nutrition science by providing the theory to help address its limitations. We end by introducing a modeling approach from nutritional ecology, termed nutritional geometry, and demonstrate how it can help to implement ecological and evolutionary theory in human nutrition to provide new direction and to better understand and manage OACD.

    The relationship between preoperative malnutrition and morbi-mortality has been documented for years. Despite the existence of tools that allow its detection, and therefore treat this entity, their introduction into clinical practice is not wide-spread. Both perioperative insulin resistance and hyperglycemia are associated with increased perioperative morbidity and length of hospital stay. The intake of carbohydrate-rich drinks 2-4h prior to surgery reduces insulin resistance. In the immediate postoperative period, the enteral route is safe and well tolerated and its early use reduces hospital stay and postoperative complications compared with parenteral nutritional support. Inmunonutrition has been proven effective to decrease postoperative complications and hospital stay. In view of these data we opted for the adoption of these measures replacing bowel rest and the indiscriminate use of postoperative parenteral nutrition. Copyright © 2013 AEC.

    This study describes clinical, laboratory, and electrodiagnostic features of a severe acute axonal polyneuropathy common to patients with acute nutritional deficiency in the setting of alcoholism, bariatric surgery (BS), or anorexia. Retrospective analysis of clinical, electrodiagnostic, and laboratory data of patients with acute axonal neuropathy. Thirteen patients were identified with a severe, painful, sensory or sensorimotor axonal polyneuropathy that developed over 2-12 weeks with sensory ataxia, areflexia, variable muscle weakness, poor nutritional status, and weight loss, often with prolonged vomiting and normal cerebrospinal fluid protein. Vitamin B6 was low in half and thiamine was low in all patients when obtained before supplementation. Patients improved with weight gain and vitamin supplementation, with motor greater than sensory recovery. We suggest that acute or subacute axonal neuropathy in patients with weight loss or vomiting associated with alcohol abuse, BS, or dietary deficiency is one syndrome, caused by micronutrient deficiencies.

    Food we eat has an important influence on health and well-being. Many eating habits are established in childhood. 456 children aged eight to 12 years participated in this survey of food eaten at school. Of all the food items eaten as a snack, 48.6% were categorised as junk. 75.8% of the sandwiches brought to school for lunch were made with white bread. Of the remaining food items brought for lunch 63.5% were of the junk variety. Compared with those who brought a snack or lunch from home, those given money to buy their own were more likely to eat junk (p daily food intake but health food practises for even a third of food intake may be of a value for health and long term eating habits.

  5. Weight Loss Nutritional Supplements

    Eckerson, Joan M.

    Obesity has reached what may be considered epidemic proportions in the United States, not only for adults but for children. Because of the medical implications and health care costs associated with obesity, as well as the negative social and psychological impacts, many individuals turn to nonprescription nutritional weight loss supplements hoping for a quick fix, and the weight loss industry has responded by offering a variety of products that generates billions of dollars each year in sales. Most nutritional weight loss supplements are purported to work by increasing energy expenditure, modulating carbohydrate or fat metabolism, increasing satiety, inducing diuresis, or blocking fat absorption. To review the literally hundreds of nutritional weight loss supplements available on the market today is well beyond the scope of this chapter. Therefore, several of the most commonly used supplements were selected for critical review, and practical recommendations are provided based on the findings of well controlled, randomized clinical trials that examined their efficacy. In most cases, the nutritional supplements reviewed either elicited no meaningful effect or resulted in changes in body weight and composition that are similar to what occurs through a restricted diet and exercise program. Although there is some evidence to suggest that herbal forms of ephedrine, such as ma huang, combined with caffeine or caffeine and aspirin (i.e., ECA stack) is effective for inducing moderate weight loss in overweight adults, because of the recent ban on ephedra manufacturers must now use ephedra-free ingredients, such as bitter orange, which do not appear to be as effective. The dietary fiber, glucomannan, also appears to hold some promise as a possible treatment for weight loss, but other related forms of dietary fiber, including guar gum and psyllium, are ineffective.

    Full Text Available Heart failure is defined as decreased ability of heart due to various reasons. It%u2019s seen 2-3% but the prevalence increases sharply after the age of seventy. The objectives of nutrition therapy in heart failure are to prevent from water retention and edema, to avoid from hard digestion and to offer a balanced diet. In order to avoid fluid retention and edema, daily sodium and fluid intake must be monitored carefully. Main dilemma of the heart failure patients is the obesity-cachexia dilemma. Since one of the main reasons of heart failure is cardiovascular diseases, in first phase, the patient may be obese. In the later phases, cachexia may show up. It was shown that cachexia is associated with mortality. Within this period, patients should not be over-fed and the patient should pass from catabolic state to anabolic state slowly. If the gastrointestinal track is functional oral/enteral feeding must be preferred. Multi vitamin and mineral supportsmay be beneficial, which may replace the increased loss, increase anti-inflammatory response and be anti-oxidants. Large, controlled and well-designed studies must be conducted in order to evaluate the benefits of nutritional practices such as nutritional assessment, enteral feeding and nutrient supports in heart failure patients.

Albino Swiss mice were fed with a food association ingested usually by human populations in northeast Brazil. This diet (Regional Basic Diet - RBD has negative effects on the growth, food intake and protein utilization in infected mice (acute phase of murine schistosomiasis. Nitrogen balance studies have also shown that infection with Schistosoma mansoni has apparently no effect on protein intestinal absorption in well nourished mice. However, the lowest absorption ratios have been detected among RBD - fed infected animals, suggesting that suprerimposed schistosome infection aggravated the nutritional status of the undernourished host. The serum proteins electrophoretic pattern, as far as albumins are concerned, is quite similar for non-infected undernourished and infected well-fed animals. So, the significance of albumins as a biochemical indicator of the nutritional status of human populations residing in endemic foci of Manson's schistosomiasis, is discussable.

    1991-07-01

    This article examines nutrition labeling history as well as the findings of nine research studies of nutrition labeling formats. Nutrition labeling regulations were announced in 1973 and have been periodically amended since then. In response to requests from consumers and health care professionals for revision of the labeling system, the Food and Drug Administration initiated a three-phase plan for reform of nutrition labeling in 1990. President Bush signed the Nutrition Labeling and Education Act in November 1990. Literature analysis revealed that only nine studies with an experimental design have focused on nutrition labeling since 1971. Four were conducted before 1975, which was the year that nutrition labeling was officially implemented, two were conducted in 1980, and three were conducted after 1986. Only two of the nine studies supported the traditional label format mandated by the Code of Federal Regulations, and one study partially supported it. Four of the nine studies that evaluated graphic presentations of nutrition information found that consumer comprehension of nutrition information was improved with a graphic format for nutrition labeling: three studies supported the use of bar graphs and one study supported the use of a pie chart. Full disclosure (ie, complete nutrient and ingredient labeling) was preferred by consumers in two of the three studies that examined this variable. The third study supported three types of information disclosure dependent upon socioeconomic class. In those studies that tested graphics, a bar graph format was significantly preferred and showed better consumer comprehension than the traditional format.

    The majority of cancer patients becomes malnourished during the course of their disease. Malnutrition deteriorates the efficiency of all kinds of oncologic interventions. As a consequence of it, treatment-related toxicity increases, hospital stay is lengthened, chances of cure and survival as well as the quality of life of the patients worsen. Nutritional status therefore influences all aspects of outcome of oncology care. In spite of this the use of nutritional therapy varies across health care providers but its application is far from being sufficient during active oncology interventions as well as rehabilitation and supportive care. It threatens not only the outcome and quality of life of cancer patients but also the success of oncologic treatments which often demand high input of human and financial resources. Meanwhile application of nutritional therapy is legally regulated in Hungary and a very recent update of the European guideline on cancer patient nutrition published in 2017 is available. Moreover, cost effectiveness of nutritional therapy has been proven in a number of studies. In this review we present the basics of nutritional therapy including nutritional screening and evaluation, nutritional plan, the role of nutrition support teams, oral, enteral and parenteral nutrition, the use of different drugs and special nutrients and the follow-up of the patients.

    Full Text Available Nutritional status has been considered to be one of the possible determinants of mortality rates in cases of acute renal failure (ARF. However, most studies evaluating possible mortality indicators in ARF cases have not focused on the nutritional status, possibly because of the difficulties involved in assessing the nutritional status of critically ill patients. Although the traditional methods for assessing nutritional status are used for ARF patients, they are not the best choice in this population. The use of nutritional support for these patients has produced conflicting results regarding morbidity and mortality. This review covers the mechanisms and indicators of malnutrition in ARF cases and the types of nutritional support that may be used.

    Full Text Available From the nutrition point of view, lipids are primarily considered as energy suppliers, their dietary intake having to be limited. In fact, lipids are sources of various fatty acids, and dietary recommendations include the required daily intakes in different fatty acids (fatty acid profile. Beyond these quantitative aspects, fatty acids are part of larger molecules, mainly triacylglycerols (TAG, that are organized in supramolecular structures as for example fat crystals and lipid droplets. Recent advances in nutrition research have demonstrated that these structures, and lipid organization in food matrices, influence digestibility and metabolism of fatty acids. Therefore, the members of the technological network Listral propose a synthesis of the knowledge about the influence of molecular and supramolecular structures of lipids on digestion and metabolic fate of dietary fatty acids originating from for the main food industry sectors. Fatty acids are mainly provided in the diet in the form of TAG, or phospholipids (PL where they are esterified in external (sn-1, sn-3 or internal (sn-2 position of the glycerol backbone. They can also be found as ethyl esters (EE in specific formulations. These molecular characteristics of the lipid molecules affect their hydrolysis and their absorption rate but also their metabolism in indifferent organs, as assessed in studies often using inter esterified fat sources. The results depend on the types of fatty acids (saturated or polyunsaturated fatty acids but also on the model used for the studies: in vitro or in vivo studies; animal model, human newborn or adult, either healthy or exhibiting some diseases. Among others, it was found that the crystal form and fat melting point as affected by the fatty acid profiles and the lipid molecular structures directly impact fatty acid absorption kinetics through modifications of lipolytic enzyme activities. However, in these studies, the relative effect of the thermal

    Parenteral nutrition became a routine therapeutic option in malnourished patients, if conventional nutritional enteral support is not effective. Cachexia and malnutrition prolong the wound healing, contribute to immunosuppression, increase morbidity and the cost of treatment. Using of a malnutrition protocol as a screening tool is necessary to sort out malnourished patients. Parenteral nutrition is therefore an important part of the multimodal therapy and from the medical and the ethical point of view is a great mistake not to feed a patient. (author)

  1. The changing nutrition scenario.

    The past seven decades have seen remarkable shifts in the nutritional scenario in India. Even up to the 1950s severe forms of malnutrition such as kwashiorkar and pellagra were endemic. As nutritionists were finding home-grown and common-sense solutions for these widespread problems, the population was burgeoning and food was scarce. The threat of widespread household food insecurity and chronic undernutrition was very real. Then came the Green Revolution. Shortages of food grains disappeared within less than a decade and India became self-sufficient in food grain production. But more insidious problems arising from this revolution were looming, and cropping patterns giving low priority to coarse grains and pulses, and monocropping led to depletion of soil nutrients and 'Green Revolution fatigue'. With improved household food security and better access to health care, clinical manifestations of severe malnutrition virtually disappeared. But the decline in chronic undernutrition and "hidden hunger" from micronutrient deficiencies was slow. On the cusp of the new century, an added factor appeared on the nutritional scene in India. With steady urban migration, upward mobility out of poverty, and an increasingly sedentary lifestyle because of improvements in technology and transport, obesity rates began to increase, resulting in a dual burden. Measured in terms of its performance in meeting its Millennium Development Goals, India has fallen short. Despite its continuing high levels of poverty and illiteracy, India has a huge demographic potential in the form of a young population. This advantage must be leveraged by investing in nutrition education, household access to nutritious diets, sanitary environment and a health-promoting lifestyle. This requires co-operation from all the stakeholders, including governments, non government organizations, scientists and the people at large.

    Full Text Available Several nutrition, food and dietary compounds have been suggested to be involved in the onset and maintenance of depressive disorders and in the severity of depressive symptoms. Nutritional compounds might modulate depression associated biomarkers and parallel the development of depression, obesity and diabetes. In this context, recent studies revealed new mediators of both energy homeostasis and mood changes (i.e. IGF-1, NPY, BDNF, ghrelin, leptin, CCK, GLP-1, AGE, glucose metabolism and microbiota acting in gut brain circuits. In this context several healthy foods such as olive oil, fish, fruits, vegetables, nuts, legumes, poultry, dairy and unprocessed meat have been inversely associated with depression risk and even have been postulated to improve depressive symptoms. In contrast, unhealthy western dietary patterns including the consumption of sweetened beverage, refined food, fried food, processed meat, refined grain, and high fat diary, biscuits, snacking and pastries have been shown to be associated with an increased risk of depression in longitudinal studies. However, it is always difficult to conclude a real prospective causal relationship from these mostly retrospective studies as depressed individuals might also change their eating habits secondarily to their depression. Additionally specific selected nutritional compounds, e.g. calcium, chromium, folate, PUFAs, vitamin D, B12, zinc, magnesium and D-serine have been postulated to be used as ad-on strategies in antidepressant treatment. In this context, dietary and lifestyle interventions may be a desirable, effective, pragmatical and non-stigmatizing prevention and treatment strategy for depression. At last, several medications (pioglitazone, metformin, exenatide, atorvastatin, gram-negative antibiotics, which have traditionally been used to treat metabolic disorders showed a certain potential to treat depression in first randomized controlled clinical trials.

  5. Childhood nutrition and poverty.

    Science.gov (United States)

    Nelson, M

    2000-05-01

    One in three children in Britain lives in poverty (households whose income was less than 50% average earnings). Low income is associated with poor nutrition at all stages of life, from lower rates of breast-feeding to higher intakes of saturated fatty acids and lower intakes of antioxidant nutrients. Moreover, there is increasing evidence that poor nutrition in childhood is associated with both short-term and long-term adverse consequences such as poorer immune status, higher caries rates and poorer cognitive function and learning ability. These problems arise primarily because parents do not have enough money to spend on food, not because money is being spent unwisely. Policy options to improve the dietary health of poor children include: giving more money to the parents by increasing Income Support (social security) payments, providing food stamps or vouchers, and using food budget standards to inform the levels of income needed to purchase an adequate diet; feeding children directly at school (not only at lunchtime but also at breakfast or homework clubs), by providing free fruit at school, and by increasing entitlement to free food amongst children living in households with low incomes; improving access to a healthy and affordable diet by first identifying 'food deserts' and then considering with retailers and local planners how best to provide food in an economical and sustainable way. The value of using food budget standards is illustrated with data relating expenditure on food to growth in children from 'at-risk' families (on low income, overcrowded, headed by a lone parent or with four or more children under 16 years of age) living in a poor area in London. Lower levels of expenditure are strongly associated with poorer growth and health, independent of factors such as birth weight, mother's height, or risk score. The present paper provides evidence that supports the need to review Government legislation in light of nutrition-related inequalities in the

    Providing nutritional support to reptile patients is a challenging and often misunderstood task. Ill reptiles are frequently anorexic and can benefit greatly from appropriate nutrition delivered via a variety of assist-feeding techniques. Neonatal reptiles can also be very challenging patients because many fail to thrive without significant efforts to establish normal feeding behaviors. This article presents ideas supporting the benefit of timely nutritional support as well as specific recommendations for implementation of assist feeding. Also discussed are a few nutritional issues that affect captive reptile species. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available Albeit a very large number of experiments have assessed the impact of various substrates on liver regeneration after partial hepatectomy, a limited number of clinical studies have evaluated artificial nutrition in liver resection patients. This is a peculiar topic because many patients do not need artificial nutrition, while several patients need it because of malnutrition and/or prolonged inability to feeding caused by complications. The optimal nutritional regimen to support liver regeneration, within other postoperative problems or complications, is not yet exactly defined. This short review addresses relevant aspects and potential developments in the issue of postoperative parenteral nutrition after liver resection.

    As with physical conditions, bipolar disorder is likely to be impacted by diet and nutrition. Patients with bipolar disorder have been noted to have relatively unhealthy diets, which may in part be the reason they also have an elevated risk of metabolic syndrome and obesity. An improvement in the quality of the diet should improve a bipolar patient's overall health risk profile, but it may also improve their psychiatric outcomes. New insights into biological dysfunctions that may be present in bipolar disorder have presented new theoretic frameworks for understanding the relationship between diet and bipolar disorder.

    In a heavy-water moderated reactor cooled by pressurized gas, an important problem from the point of view, of the reactor block and its economics is the choice of the gas supply system. In the pressure tube solution, the whole of the reactor block structure is at a relatively low temperature, whereas the gas supply equipment is at that of the gas, which is much higher. These parts, through which passes the heat carrying fluid have to present as low a resistance as possible to it so as to avoid costly extra blowing power. Finally, they may only be placed in the reactor block after it has been built; the time required for putting them in position should therefore not be too long. The work reported here concerns the various problems arising in the case of each channel being supplied individually by a tube at the entry and the exit which is connected to a main circuit made up of large size collectors. This individual tubing is sufficiently flexible to absorb the differential expansion and the movement of its ends without stresses or prohibitive reactions being produced; the tubing is also of relatively short length so as to reduce the pressure head of the pressurized gas outside the channels; the small amount of space taken up by the tubing makes it possible to assemble it in a manner which is satisfactory from the point of view both of the time required and of the technical quality.

    There is a new merging of health economics and nutrition disciplines to assess the impact of diet on health and disease prevention and to characterise the health and economic aspects of specific changes in nutritional behaviour and nutrition recommendations. A rationale exists for developing the field of nutrition economics which could offer a better understanding of both nutrition, in the context of having a significant influence on health outcomes, and economics, in order to estimate the absolute and relative monetary impact of health measures. For this purpose, an expert meeting assessed questions aimed at clarifying the scope and identifying the key issues that should be taken into consideration in developing nutrition economics as a discipline that could potentially address important questions. We propose a first multidisciplinary outline for understanding the principles and particular characteristics of this emerging field. We summarise here the concepts and the observations of workshop participants and propose a basic setting for nutrition economics and health outcomes research as a novel discipline to support nutrition, health economics and health policy development in an evidence and health-benefit-based manner.

A total of 452 patients with gastrointestinal cancer were selected, including 156 gastric cancer,117 colon cancer, and 180 rectal cancer. The nutritional risk screening 2002(NRS2002) was applied to grade the nutritional risk. A multi-frequency bioelectrical impedance analysis was used to measure the patients' body composition. Albumin (Alb), prealbumin(PA), transferring(Tf), retinol binding protein(RBP), red blood cell(RBC), hemoglobin (Hb), haematocrit(Hct) were measured after fasting. The rate of patients with NRS2002 score more than 3 was 70.5%(110/156) for gastric cancer, 53.8%(63/117) for colon cancer, and 46.7%(86/180) for rectal cancer.

    In Canada, increased morbidity and shorter life expectancy have been found among those with lower incomes and lower levels of education, but there has been little examination of socioeconomic variation in food and nutrient intake. Using data from the 2004 Canadian Community Health Survey, we examined the relationship between household income and education level and adults' and children's intakes of energy, fibre, micronutrients, and number of servings consumed of food groups from Canada's Food Guide. To explore the public health significance of observed associations, we estimated the prevalence of inadequacy for selected nutrients for adults, stratifying by household income, education level, and sex. We found that a higher household income adequacy and (or) higher levels of education were associated with increased consumption of milk and alternatives, and vegetables and fruit, and significantly higher vitamin, mineral, and fibre intakes among both adults and children. The prevalence of inadequate nutrient intakes among adults was higher among adults with the lowest level of income adequacy or educational attainment, compared with others. Our results suggest that the nutritional quality of Canadians' food intakes is, in part, a function of their social position. The impact of policy and program interventions needs to be examined across socioeconomic strata to ensure that actions reduce rather than exacerbate nutrition inequities.

  5. School nutrition survey.

    Food we eat has an important influence on health and well-being. Many eating habits are established in childhood. 456 children aged eight to 12 years participated in this survey of food eaten at school. Of all the food items eaten as a snack, 48.6% were categorised as junk. 75.8% of the sandwiches brought to school for lunch were made with white bread. Of the remaining food items brought for lunch 63.5% were of the junk variety. Compared with those who brought a snack or lunch from home, those given money to buy their own were more likely to eat junk (p < 0.01). Food eaten at school reflects approximately one third of a child\\'s daily food intake but health food practises for even a third of food intake may be of a value for health and long term eating habits. Nutritional education with the reinforcement of high nutritional standards in schools could improve the situation.

    Team sports are based on intermittent high-intensity activity patterns, but the exact characteristics vary between and within codes, and from one game to the next. Despite the challenge of predicting exact game demands, performance in team sports is often dependent on nutritional factors. Chronic issues include achieving ideal levels of muscle mass and body fat, and supporting the nutrient needs of the training program. Acute issues, both for training and in games, include strategies that allow the player to be well fuelled and hydrated over the duration of exercise. Each player should develop a plan of consuming fluid and carbohydrate according to the needs of their activity patterns, within the breaks that are provided in their sport. In seasonal fixtures, competition varies from a weekly game in some codes to 2-3 games over a weekend road trip in others, and a tournament fixture usually involves 1-3 days between matches. Recovery between events is a major priority, involving rehydration, refuelling and repair/adaptation activities. Some sports supplements may be of value to the team athlete. Sports drinks, gels and liquid meals may be valuable in allowing nutritional goals to be met, while caffeine, creatine and buffering agents may directly enhance performance. Copyright © 2011 S.

    There has been an increase in the knowledge and interest on nutrition, and functional foods have gained popularity over the last few decades, and the trend is increasing. Probiotics and prebiotics are among the most studied functional foods. Nutrition economics has been defined as the discipline dedicated to researching and characterising health and economic outcomes in nutrition for the benefit of society. The concept and its application to probiotics and prebiotics will be discussed in terms of health and economic benefits and their evaluation. Health economics and concrete applications showing how to maximise long-term nutritional benefits will contribute to motivate consumers in making food choices based on a rational understanding of their own interest. We present a model that shows that nutrition economics can be used as an analytical tool for product and service network development.

  8. Nutritional status and nutritional risk in patients with neuroendocrine tumors

    DEFF Research Database (Denmark)

    2018-01-01

    BACKGROUND: Malnutrition is frequent among patients with malignancies and associated with impaired function, reduced quality of life and increased mortality. Few data are available in patients with neuroendocrine tumors (NET) on nutritional status, nutritional risk, and nutrition impact symptoms...... (NIS). We aimed to assess nutritional status (NS) and risk, level of function and associations with NIS in NET patients. METHODS: In a cross-sectional study of NET patients, we measured body mass index (BMI) and handgrip strength (HGS) as markers of NS and muscle function assessed by HGS....... The nutritional risk score (NRS) was determined by NRS-2002. NIS was assessed by the eating symptoms questionnaire (ESQ), and disease-related appetite questionnaire (DRAQ).

    In 1990, the Unicef conceptual framework for nutrition recognised the role of care, along with household food security and health services and environment, as one of the three underlying factors of child survival, growth, and development. This model has been adopted at a policy level at the International Conference on Nutrition (Rome, 1992) and over the past ten years the concept of care has been refined through literature reviews, consultative meetings and empirical works. "Care is the provision in the household and the community of time, attention, and support to meet the physical, mental, and social needs of the growing child and other household members". Basically, care refers to the actions of caregivers (mainly, but not only mothers) that translate food and health resources into positive outcomes for the child's nutrition. Even under circumstances of poverty, enhanced caregiving can optimise the use of resources to promote good nutrition. Care practices have been grouped into six categories: care for women, breastfeeding and child feeding practices, psychosocial care, food preparation, hygiene practices, household health practices. They cover a wide range of behaviours, are often culturally specific and are daily, repetitive, and time-consuming activities. It must be underlined that the way care practices are performed (i.e., quality of care) is as important as the practices themselves. It has also been emphasised that children play a significant role in determining the quality of care that they receive, through an interactive process: an active child elicits more care from the caregiver, who is in turn more responsive. Care resources at household level have been described according to three categories: human (knowledge, beliefs, education, physical and mental health of the caregiver), economic (control on income, workload and time), and organisational (alternate caregivers, community support). But the availability of care also depends on support at the

    Climate change further exacerbates the enormous existing burden of undernutrition. It affects food and nutrition security and undermines current efforts to reduce hunger and promote nutrition. Undernutrition in turn undermines climate resilience and the coping strategies of vulnerable populations. The objectives of this paper are to identify and undertake a cross-sectoral analysis of the impacts of climate change on nutrition security and the existing mechanisms, strategies, and policies to address them. A cross-sectoral analysis of the impacts of climate change on nutrition security and the mechanisms and policies to address them was guided by an analytical framework focused on the three 'underlying causes' of undernutrition: 1) household food access, 2) maternal and child care and feeding practices, 3) environmental health and health access. The analytical framework includes the interactions of the three underlying causes of undernutrition with climate change,vulnerability, adaptation and mitigation. Within broad efforts on climate change mitigation and adaptation and climate-resilient development, a combination of nutrition-sensitive adaptation and mitigation measures, climate-resilient and nutrition-sensitive agricultural development, social protection, improved maternal and child care and health, nutrition-sensitive risk reduction and management, community development measures, nutrition-smart investments, increased policy coherence, and institutional and cross-sectoral collaboration are proposed as a means to address the impacts of climate change to food and nutrition security. This paper proposes policy directions to address nutrition in the climate change agenda and recommendations for consideration by the UN Framework Convention on Climate Change (UNFCCC). Nutrition and health stakeholders need to be engaged in key climate change adaptation and mitigation initiatives, including science-based assessment by the Intergovernmental Panel on Climate Change (IPCC

    In this review, the authors summarize current knowledge on maternal nutritional requirements during pregnancy, with a focus on the nutrients that have been most commonly investigated in association with birth outcomes. Data sourcing and extraction included searches of the primary resources establishing maternal nutrient requirements during pregnancy (e.g., Dietary Reference Intakes), and searches of Medline for "maternal nutrition"/[specific nutrient of interest] and "birth/pregnancy outcomes," focusing mainly on the less extensively reviewed evidence from observational studies of maternal dietary intake and birth outcomes. The authors used a conceptual framework which took both primary and secondary factors (e.g., baseline maternal nutritional status, socioeconomic status of the study populations, timing and methods of assessing maternal nutritional variables) into account when interpreting study findings. The authors conclude that maternal nutrition is a modifiable risk factor of public health importance that can be integrated into efforts to prevent adverse birth outcomes, particularly among economically developing/low-income populations.

    It is the position of the Academy of Nutrition and Dietetics, School Nutrition Association, and Society for Nutrition Education and Behavior that comprehensive, integrated nutrition programs in preschool through high school are essential to improve the health, nutritional status, and academic performance of our nation's children. Through the continued use of multidisciplinary teams, local school needs will be better identified and addressed within updated wellness policies. Updated nutrition standards are providing students with a wider variety of fruits, vegetables, and whole grains, while limiting sodium, calories, and saturated fat. Millions of students enjoy school meals every day in the US, with the majority of these served to children who are eligible for free and reduced-priced meals. To maximize impact, the Academy, School Nutrition Association, and Society for Nutrition Education and Behavior recommend specific strategies in the following key areas: food and nutrition services available throughout the school campus, nutrition initiatives such as farm to school and school gardens, wellness policies, nutrition education and promotion, food and beverage marketing at school, and consideration of roles and responsibilities.

    The Update on the Nutrition Situation, 1994 was published in early 1995 by the United Nations Subcommittee on Nutrition. Thus, data available at the country level about estimates of the nutritional situation now provide trends of prevalences of underweight children in 35 countries for the 1990s. In Sub-Saharan Africa recent deterioration has occurred as a result of the general worsening of nutrition in Africa. However, in the Near East, North Africa, and South America the generally improving trends of the 1980s seem to be continuing with the likelihood of reaching the prevalences of the developed countries by the year 2000. A surveillance system in Bangladesh indicates improvement from 1990 to 1993; however, India data for 1991/92 indicate deterioration in 3 states and no significant change in 4, possibly connected the economic slowdown in the early 1990s. In many countries of southeast Asia, China, Middle America and the Caribbean, South America, the Near East and North Africa the improvement of rates could result in halving the prevalences of underweight children. The gross domestic product (GDP) is an important indicator of nutritional performance. During 1985-92 in Sub-Saharan Africa GDP declined by 0.8% and consequently the nutritional situation also deteriorated. In other areas of the world the GDP growth rates improved after 1990 and the underweight trends in the early 1990s were generally similar to those of the late 1980s. The nutritional improvement outside Sub-Saharan Africa and possibly India continued in the early 1990s. Rapid economic growth was associated with improving nutrition in Thailand and Vietnam in the 1980s and also to a smaller extent for Indonesia and China. Faster than average improvement is plausible for Jamaica, Sri Lanka, and Zimbabwe. Deteriorating cases are Ethiopia, Madagascar, and Rwanda. Economic growth, health, education, and community-based nutrition programs all contribute to improving nutrition.

    Weight loss and malnutrition are common in cancer patients. Although weight loss is predominantly due to loss of fat mass, the morbidity risk is given by the decrease in muscle mass. The assessment of nutritional status is essential for a diagnosis of nutritional compromise and required for the multidisciplinary approach. Subjective global assessment (SGA) is made by the patients nutritional symptoms and weight loss. The objective assessment, a significant weight loss (>10%) for 6 months is considered an indicator of nutritional deficiency. The mean body index, body fat mass and body protein mass are decreased as cancer stage increases. The biochemical data of albumin, cholesterol, triglyceride, Zn, transferrin, total lymphocyte count are decreased in advanced cancer stage. Daily energy intake, cabohyderate and Vit B1 intake is decreased according to cancer stage. The patients are divided into three groups according to SGA. The three groups showed a significant difference in body weight, 1 month weight loss%, 6 month weight loss%, body mass index, mid arm circumference, albumin, energy intake, as well as carbohyderate intake protein and energy malnutrition. Nutritional assessment is of great importance because undernutrition has been shown to be associated with increase in stomach cancer associated morbidity and mortality. The authors concluded that nutritional assessment should be done in cancer patients preoperatively, and with adequate nutritional support, the morbidity and mortality would be decreased.

    Few supplement combinations that are marketed to athletes are supported by scientific evidence of their effectiveness. Quite often, under the rigor of scientific investigation, the patented combination fails to provide any greater benefit than a group given the active (generic) ingredient. The focus of this chapter is supplement combinations and dosing strategies that are effective at promoting an acute physiological response that may improve/enhance exercise performance or influence chronic adaptations desired from training. In recent years, there has been a particular focus on two nutritional ergogenic aids—creatine monohydrate and protein/amino acids—in combination with specific nutrients in an effort to augment or add to their already established independent ergogenic effects. These combinations and others are discussed in this chapter.

    Full Text Available Introduction. Chronic diseasesare the leading cause of population mortality worldwide. They have reached alarming proportions. This is linked to the epidemiological transition that has changed the health picture dominated by infectious diseases, by the progressive disappearance of infectious diseases and the proliferation of chronic diseases. This phenomenon has not spared Algeria, where diabetes is one of the major problems of public health. Studies have revealed a female predominance of diabetes around the world and nationally, as well as a greater number of deaths. On the contrary, a low interest was observed for this gender characteristic. In addition to the medicinal treatment prescribed for diabetes, dietetic measures are recommended, where emphasis was placed on the importance of nutritional intake in maintaining the glycemic balance.Objective. In this context, we undertook a socio-anthropological study with the main objective of shedding light on the complexity of these food practices. Methodology. We have mobilized a qualitative approach based on twenty interviews, conducted at home, with diabetic patients living in Oran. .Résults The influence of social gender relationships was noted on the dietary practices of diabetic women.The criteria of taste appreciation, pleasure of eating, and sense of sharing were highlighted in the choice of foods. Eating habits appeared as very strong identity markers, imbued with culinary traditions. Conclusion. This brings us to the importance of a socio-anthropological approach to diet in patients with diabetes.

    Traditional nutrition evaluations not only require the use of numerous tables and lists to provide sufficient recommendations for patients' diets but are also very time-consuming due to cross-referencing and calculations. To personalize patient assessments, this study implemented a Clinical Nutritional Information System (CNIS) to help hospital dietitians perform their daily work more effectively in terms of time management and paper work. The CNIS mainly targets in-patients who require cancer-nutrition counselling. The development of the CNIS occurred in three phases. Phase 1 included system design and implementation based on the Nutrition Care Process and Model (NCPM) and the Patient Nutrition Care Process. Phase 2 involved a survey to characterize the efficiency, quality and accuracy of the CNIS. In Phase 3, a second survey was conducted to determine how well dietitians had adapted to the system and the extent of improvement in efficiency after the CNIS had been available online for three years. The work time requirements decreased by approximately 58% with the assistance of the CNIS. Of the dietitians who used the CNIS, 95% reported satisfaction, with 91.66% indicating that the CNIS was really helpful in their work. However, some shortcomings were also evident according to the results. Dietitians favoured the standardization of nutritional intervention and monitoring. The CNIS meets the needs of dietitians by increasing the quality of nutritional interventions by providing accurate calculations and cross-referencing for information regarding patients' conditions, with the benefit of decreasing the processing time, such as handwritten documentation. In addition, the CNIS also helps dietitians statistically analyse each patient's personal nutritional needs to achieve nutritional improvement. Copyright © 2017 Elsevier B.V. All rights reserved.

    It is important to offer continuous medical service without interrupting everyone's various job functions at the Tama Numbu-Chiiki Hospitals in order to secure the quality and safety of home medical care to patients and their families. From 1998 up to the present, home intravenous hyper alimentation (home IVH) has been introduced by individually exchanging information that was based on items such as clinical case, doctor and caregiver in charge of the day, and introductory information. Five years have passed since we started an introduction of home IVH, and it appears that the medical cooperation of home IVH between the Minami-tama medical region and its neighboring area has been established. Then, we arranged an examination of the past 2 years based on the 57 patients who elected to choose home IVH instruction. Consequently, we created "home IVH introduction plan document" in standardizing a flow from home IVH introduction to post-hospital intervention. Since November of 2003, the plan document has been utilized and carried out to 5 patients by the end of February in 2004. This home IVH introduction plan document was able to clarify the role of medical person in connection with the patient. Therefore, we could not only share the information, but also could transfer medical care smoothly from the hospital to the patient's home.

    Enteral nutrition is widely used in hospitals as a means of nutritional support and therapy for different diseases. Enteral nutrition must fulfil the energy needs of the body, be balanced by the nutrient composition and meet patient’s nutritional needs. Meat is a source of full-value animal protein, vitamins and minerals. On the basis of this research, recipes and technology for a meat-based enteral nutrition product were developed. The product is a ready-to-eat sterilised mixture in the form of a liquid homogeneous mass, which is of full value in terms of composition and enriched with vitamins and minerals, consists of particles with a size of not more than 0.3 mm and has the modified fat composition and rheological characteristics that are necessary for passage through enteral feeding tubes. The study presents experimental data on the content of the main macro- and micro-nutrients in the developed product. The new product is characterised by a balanced fatty acid composition, which plays an important role in correction of lipid metabolism disorders and protein-energy deficiency, and it is capable of satisfying patients’ daily requirements for vitamins and the main macro- and microelements when consuming 1500-2000 ml. Meat-based enteral nutrition can be used in diets as a standard mixture for effective correction of the energy and anabolic requirements of the body and support of the nutritional status of patients, including those with operated stomach syndrome.

    Athletes obtain nutritional information from their coaches, yet their competency in this area is lacking. Currently, no research exists in the UK which has a different coach education system to many other countries. Therefore, the aim of this study was to evaluate the sports nutrition knowledge of UK coaching certificate (UKCC) level 2 and 3, hockey and netball qualified coaches. All coaches (n = 163) completed a sports nutrition questionnaire to identify: (a) if they provided nutritional advice; (b) their level of sport nutrition knowledge; and (c) factors that may have contributed to their level of knowledge. Over half the coaches provided advice to their athletes (n = 93, 57.1%), even though they were not competent to do so. Coaches responded correctly to 60.3 ± 10.5% of all knowledge questions with no differences between those providing advice and those who did not (p > 0.05). Those coaches who had undertaken formal nutrition training achieved higher scores than those who had not (p sports coaches would benefit from continued professional development in sports nutrition to enhance their coaching practice.

    Full Text Available Genetics is an important piece of every individual health puzzle. The completion of the Human Genome Project sequence has deeply changed the research of life sciences including nutrition. The analysis of the genome is already part of clinical care in oncology, pharmacology, infectious disease and, rare and undiagnosed diseases. The implications of genetic variations in shaping individual nutritional requirements have been recognised and conclusively proven, yet routine use of genetic information in nutrition and dietetics practice is still far from being implemented. This article sets out the path that needs to be taken to build a framework to translate gene–nutrient interaction studies into best-practice guidelines, providing tools that health professionals can use to understand whether genetic variation affects nutritional requirements in their daily clinical practice.

    An advisory group of experts, comprising nutritionists, analysts and plant breeders, discussed the desirability of nutritional goals for plant breeding and attempted to specify the deficiencies of various cereal crops in essential nutrients. It considered the plant factors influencing the value for human and animal nutrition and the feasibility of improving these by genetic and plant breeding methods. Methods of assaying nutritional quality were discussed, particularly in relation to the need for rapid, inexpensive methods capable of being used as screening procedures in plant breeding programmes. The proceedings contain 9 scientific papers and a conclusion and recommendations, including a review of the chemical cuzymatic, microbiological and animal assay techniques that are available

    During 1979-1980 calculations of risk from waste transportation by truck (fire following collision) and fire in temporary storage for waste were performed. A modified version of the consequence model of WASH-1400 (CRAC) was used. Two exposure pathways dominated the results: external exposure from material on the ground and exposure via nutrition. Many of the parameters entering into the nutrition calculations will depend upon local conditions, like soil composition, crop yield, etc. It was decided to collect detailed comments upon the CRAC nutritions model and parameter values from radioecologists in the four Nordic countries. Four alternate sets of parameter values were derived from these comments, and new risk calculations were performed

    At the time of independence majority of Indians were poor. In spite of spending over 80 per cent of their income on food, they could not get adequate food. Living in areas of poor environmental sanitation they had high morbidity due to infections; nutrition toll due to infections was high because of poor access to health care. As a result, majority of Indians especially children were undernourished. The country initiated programmes to improve economic growth, reduce poverty, improve household food security and nutritional status of its citizens, especially women and children. India defined poverty on the basis of calorie requirement and focused its attention on providing subsidized food and essential services to people below poverty line. After a period of slow but steady economic growth, the last decade witnessed acceleration of economic growth. India is now one of the fastest growing economies in the world with gross domestic product (GDP) growth over 8 per cent. There has been a steady but slow decline in poverty; but last decade's rapid economic growth did not translate in to rapid decline in poverty. In 1970s, country became self sufficient in food production; adequate buffer stocks have been built up. Poor had access to subsidized food through the public distribution system. As a result, famines have been eliminated, though pockets of food scarcity still existed. Over the years there has been a decline in household expenditure on food due to availability of food grains at low cost but energy intake has declined except among for the poor. In spite of unaltered/declining energy intake there has been some reduction in undernutrition and increase in overnutrition in adults. This is most probably due to reduction in physical activity. Under the Integrated Child Development Services (ICDS) programme food supplements are being provided to children, pregnant and lactating women in the entire country. In spite of these, low birth weight rates are still over 30 per

    Food irradiation is a preservation method comparable to others that use heat. Some advantages and disadvantages are discussed. Ionizing radiations provided by specific radioactive substances: Cobalt-60 and Cesium-137, or by machines (electron accelerators and X-ray devices), are employed to eliminate living organisms which are harmful to human health or cause food spoilage. Several applications are listed. As any other food preservation method, it does not substitute good manufacturing practices but complements them. Being perhaps the most studied food preservation method, its wholesomeness is guaranteed by the World Health Organization (WHO), the Food and Agricultural Organization (FAO), the International Atomic Energy Agency (IAEA), the American Medical Association, The American Dietists Association, among others. Like in any other food preservation method, some nutritional and sensory losses can occur after an irradiation treatment; so, processing conditions are chosen to minimize these changes. Generally, nutrients are well protected within the food because there are many different molecules able to react with radiation. Some significant nutrient losses referred to in literature are usually found only when irradiating experimental mixtures of an isolated diluted food component and water. The evaluation concludes that macro nutrients like proteins, lipids and carbohydrates are scarcely altered in their nutritional value after a treatment carried out under good irradiation practices. Regarding micro nutrients, minerals are stable, and some vitamins are slightly sensitive, mainly thiamine, ascorbic acid, and tocopherols, being their losses smaller than 15 - 20% which are comparable with those found in foods preserved by other methods. Besides, the impact that food irradiation would have on consumers' vitamins intake should be assessed considering the whole diet contribution, as many products are not likely to be irradiated. Confidence in food irradiation is such

    In spite of amazing progress in food supply and nutritional science, and a striking increase in life expectancy of approximately 2.5 months per year in many countries during the previous 150 years, modern nutritional research has a great potential of still contributing to improved health for future generations, granted that the revolutions in molecular and systems technologies are applied to nutritional questions. Descriptive and mechanistic studies using state of the art epidemiology, food intake registration, genomics with single nucleotide polymorphisms (SNPs) and epigenomics, transcriptomics, proteomics, metabolomics, advanced biostatistics, imaging, calorimetry, cell biology, challenge tests (meals, exercise, etc.), and integration of all data by systems biology, will provide insight on a much higher level than today in a field we may name molecular nutrition research. To take advantage of all the new technologies scientists should develop international collaboration and gather data in large open access databases like the suggested Nutritional Phenotype database (dbNP). This collaboration will promote standardization of procedures (SOP), and provide a possibility to use collected data in future research projects. The ultimate goals of future nutritional research are to understand the detailed mechanisms of action for how nutrients/foods interact with the body and thereby enhance health and treat diet-related diseases.

    Full Text Available Introduction and purpose of the work. Diabetic kidney disease usually occurs at a late stage of diabetes and is often the result of long-term disease failure. As in diabetes alone, the diet used by the patient has a significant influence on how quickly the nephropathy will proceed. The aim of the study is to present issues related to dietary management in kidney diseases being complication of diabetes. . Brief description of the state of knowledge. People with type 2 diabetes usually struggle with overweight or obesity and hypertension. Obesity is one of the factors that causes the progression of diabetic kidney disease. A diet for such people requires a negative energy balance. Insulin itself increases appetite and the frequent occurrence of hypoglycaemia is the reason for increasing the number of meals. Summary. Diet is a very important element in the treatment of diabetes. It determines the maintenance of proper blood glucose and lipid (lipid levels and optimal blood pressure values. A well-chosen diet reduces the risk of diabetic complications, as well as reduces the risk of vascular diseases. The right model of nutrition also plays an important role in the prevention and treatment of chronic diabetes complications.

  20. Diet, nutrition, and cancer

    Energy Technology Data Exchange (ETDEWEB)

    Palmer, S.

    1985-01-01

    Evidence pertaining to the role of dietary factors in carcinogenesis comes from both epidemiological studies and laboratory experiments. In 1982, the Committee on Diet, Nutrition, and Cancer of the National Research Council conducted a comprehensive evaluation of this evidence. That assessment as well as recent epidemiological and laboratory investigations suggest that a high fat diet is associated with increased susceptibility to cancer of different sites, particularly the breast and colon, and to a lesser extent, the prostate. Current data permit no definitive conclusions about other dietary macroconstituents including cholesterol, total caloric intake, protein, carbohydrates and total dietary fiber. Specific components of fiber, however, may have a protective effect against colon cancer. In epidemiological studies, frequent consumption of certain fruits and vegetables, especially citrus fruits and carotene-rich and cruciferous vegetables, is associated with a lower incidence of cancers at various sites. The specific components responsible for these effects are not clearly identified, although the epidemiological evidence appears to be most consistent for a protective effect of carotene on lung cancer and less so for vitamins A and C and various cancer sites. The laboratory evidence is most consistent for vitamin A deficiency and enhanced tumorigenesis, and for the ability of various nonnutritive components in cruciferous vegetables to block in-vivo carcinogenesis. The data for minerals and carcinogenesis are extremely limited, although preliminary evidence from both epidemiological and laboratory studies suggests that selenium may protect against overall cancer risk. 402 references.

    Directory of Open Access Journals (Sweden)

    Christiane Hillger

    2008-03-01

    Full Text Available Abraham Maslow (1908 – 1970 has set up a hierarchy of five levels of basic needs. Of those that are considered to be basic physiological needs hunger, thirst as well as bodily comforts are considered to be the most important. Physiological needs are the strongest needs because if a person were deprived on all needs it is these physiological needs that would take the highest priority. As food is characterized as a basic need, we should have a special view on our daily food and our handling of it. Most people do not act careful with their daily intake of food. In the last decades, the increases of nutrition-associated diseases such as overweight and obesity and on the other hand underweight have been recorded. From a life-span approach, the problem has its offset point in the early age of development, namely in children and adolescents. Malnutrition, overweight and obesity limit children’s personal quality of life in terms of unhappiness with their own body, opposition or even rejection in peer group communication and general difficulties in day-to-day social interaction. A close connection between physical stature and the development of a negative self-concept and a low self-esteem is postulated.

  2. [Nutrition and fertility].

    Szostak-Węgierek, Dorota

    2011-01-01

    There is a growing body of evidence that nutritional habits may have a significant effect on both male and female fertility. Maintenance of normal body mass may be effective in the prevention of infertility resulting from ovulatory disorders. Underweight and, to a larger degree, overweight and/or obesity, are related to the enhanced risk of infertility. Insulin resistance is an important pathogenic mechanism that may impair ovulation. Adequate intake of monounsaturated fatty acids, derived mainly from vegetable fats, as well as avoidance of trans isomers of unsaturated fatty acids which are present in industrially produced cakes and sweets, crisps, fast-foods, powdered soups and hard margarines, may be effective in the prevention of infertility in females. Choice of plant rather than animal sources of proteins, decrease in glycemic load of the diet, use of dietary supplements containing iron and folic acid, could also be beneficial. Avoidance of vitamin B12 deficiency and its supplementation seem to be important in the prevention of early miscarriages. Sufficient intake of antioxidants also promotes female reproductive functions. Free radical processes play an important role in the development of male factor infertility. It was shown that proper intake or supplementation with antioxidants may be effective in its prevention and treatment. Such nutrients as zinc, selenium and folic acid act beneficially on sperm quality. A well-balanced diet seems to play an important role in the prevention of infertility in both sexes.

  3. Nutrition and cognitive impairment

    Science.gov (United States)

    Hernando-Requejo, Virgilio

    2016-07-12

    Dementia, closely linked to environmental predisposing factors such as diet, is a public health problem of increasing magnitude: currently there are more than 35 million patients with Alzheimer´s disease, and is expected to exceed 135 million by 2050. If we can delay the development of dementia 5 years will reduce its prevalence by 50%. Patients with dementia modify their diet, and it has been reported in them deficits, among others, of folic acid, vitamin B12, B6, C, E, A, D, K, beta carotene and omega 3 fatty acids, that must be resolved with proper diet and with extra contributions if needed in some cases. But to reduce, or at least delay, the prevalence of dementia we advocate prevention through proper diet from the beginning of life, an idea that is reinforced given that cardiovascular risk factors are related directly to the development of dementia. A lot of literature are available that, although with limits, allows us to make nutritional recommendations for preventing cognitive impairment. Better results are achieved when complete diets have been studied and considered over specific nutrients separately. Particularly, the Mediterranean diet has great interest in this disease, since it ensures a high intake of vegetables, fruits, nuts, legumes, cereals, fish and olive oil, and moderate intake of meat, dairy products and alcohol. We will focus more on this article in this type of diet.

    2014-07-01

    Early human food cultures were plant-based. Major religions such as Hinduism and Buddhism have recommended a vegetarian way of life since their conception. The recorded history of vegetarian nutrition started in the sixth century bc by followers of the Orphic mysteries. The Greek philosopher Pythagoras is considered the father of ethical vegetarianism. The Pythagorean way of life was followed by a number of important personalities and influenced vegetarian nutrition until the 19th century. In Europe, vegetarian nutrition more or less disappeared during the Middle Ages. In the Renaissance era and in the Age of Enlightenment, various personalities practiced vegetarianism. The first vegetarian society was started in England in 1847. The International Vegetarian Society was founded in 1908 and the first vegan society began in 1944. Prominent vegetarians during this time included Sylvester Graham, John Harvey Kellogg, and Maximilian Bircher-Benner. A paradigm shift occurred at the turn of the 21st century. The former prejudices that vegetarianism leads to malnutrition were replaced by scientific evidence showing that vegetarian nutrition reduces the risk of most contemporary diseases. Today, vegetarian nutrition has a growing international following and is increasingly accepted. The main reasons for this trend are health concerns and ethical, ecologic, and social issues. The future of vegetarian nutrition is promising because sustainable nutrition is crucial for the well-being of humankind. An increasing number of people do not want animals to suffer nor do they want climate change; they want to avoid preventable diseases and to secure a livable future for generations to come. © 2014 American Society for Nutrition.

    The prevalence of disease-related malnutrition in Western European hospitals is estimated to be about 30%. There is no consensus whether poor nutritional status causes poorer clinical outcome or if it is merely associated with it. The intention with all forms of nutrition support is to increase uptake of essential nutrients and improve clinical outcome. Previous reviews have shown conflicting results with regard to the effects of nutrition support. To assess the benefits and harms of nutrition support versus no intervention, treatment as usual, or placebo in hospitalised adults at nutritional risk. We searched Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library, MEDLINE (Ovid SP), Embase (Ovid SP), LILACS (BIREME), and Science Citation Index Expanded (Web of Science). We also searched the World Health Organization International Clinical Trials Registry Platform (www.who.int/ictrp); ClinicalTrials.gov; Turning Research Into Practice (TRIP); Google Scholar; and BIOSIS, as well as relevant bibliographies of review articles and personal files. All searches are current to February 2016. We include randomised clinical trials, irrespective of publication type, publication date, and language, comparing nutrition support versus control in hospitalised adults at nutritional risk. We exclude trials assessing non-standard nutrition support. We used standard methodological procedures expected by Cochrane and the Cochrane Hepato-Biliary Group. We used trial domains to assess the risks of systematic error (bias). We conducted Trial Sequential Analyses to control for the risks of random errors. We considered a P value of 0.025 or less as statistically significant. We used GRADE methodology. Our primary outcomes were all-cause mortality, serious adverse events, and health-related quality of life. We included 244 randomised clinical trials with 28,619 participants that met our inclusion criteria. We considered all trials to be at high risk of bias. Two

    2015-02-07

    In my over three decades of work in the field of food and nutrition, I have participated in many efforts that seek new policy initiatives in the hopes that these programs can curb rates of obesity and chronic disease and help consumers make healthier dietary choices. Because of the profound effect that many of these policies have on consumers, the food environment, federal nutrition assistance programs and subsequent policy and regulatory recommendations, it is imperative that only the strongest, best available evidence is used to set policy. This review evaluates methods by which current nutrition policies use scientific research as well as provides recommendations for how best to ensure future nutrition policies are truly science-based and likely to have a meaningful impact on public health. Specifically, this review will: Describe the current food and nutrition policy environment in the US Examine how science is used in federal food and nutrition policymaking efforts, using the Dietary Guidelines for Americans (DGA) as an example Describe strong versus weak science as well as what types of studies are most appropriate for use in policymaking Discuss the potential effects and consequences of making policy recommendations in the absence of scientific consensus or agreement Make recommendations to support the present and ongoing development of science-based policy likely to positively impact public health.

  9. Metabonomics in neonatal nutrition research

    Full Text Available Maternal obesity and early post-natal nutrition might associate with increased obesity risk in later life. We have investigated the effect of breastfeeding and infant formulas differing in protein content on the urinary and fecal metabolism of term infants born from overweight and obese mothers using a metabonomic approach. Metabolic differences were observed between breast and formula fed infants both in urine and stool samples. Metabolic profiles of formula fed infants exhibited a distinct metabolic pattern that was associated with the processing of dietary proteins from the host and the gut microbiota. Metabonomics appears as a powerful tool to measure the physiological response to infant formula versus the gold standard breastfeeding. In future, nutritional phenotyping will combine metabonomics and nutritional profiling to study specific nutritional requirements and measure the efficacy of tailored nutritional interventions on growth and development endpoints. It will then open novel opportunities to develop targeted nutritional solutions for health maintenance and disease prevention. Proceedings of the 11th International Workshop on Neonatology and Satellite Meetings · Cagliari (Italy · October 26th-31st, 2015 · From the womb to the adultGuest Editors: Vassilios Fanos (Cagliari, Italy, Michele Mussap (Genoa, Italy, Antonio Del Vecchio (Bari, Italy, Bo Sun (Shanghai, China, Dorret I.

    This research sought to determine how often nutrition marketing is used on labels of foods that are high in saturated fat, sodium, and/or sugar. All items packaged with food labels (N = 56,900) in all 6 grocery stores in Grand Forks, ND were surveyed. Marketing strategy, nutrient label information, if the product was fruit/or milk based, and target age. Frequency distributions were computed. Forty-nine percent of all products contained nutrition marketing and of those, 48% had both nutrition marketing and were high in saturated fat, sodium and/or sugar (11%, 17%, and 31% respectively). Seventy-one percent of products marketed to children had nutrition marketing. Of those, 59% were high in saturated fat, sodium and/or sugar content, with more than half being high in sugar. The most commonly used nutrition marketing statements were "good source of calcium", "reduced/low/fat free", and "food company's health symbol". Nutrition marketing is commonly used on products high in saturated fat, sodium and/or sugar and is more often used on products marketed toward children than products marketed toward adults. Current food industry symbols may not be helping consumers select foods low in saturated fat, sodium or sugar. Published by Elsevier Inc.

  11. Nutritional Therapy in Liver Transplantation

    Full Text Available Protein-energy malnourishment is commonly encountered in patients with end-stage liver disease who undergo liver transplantation. Malnutrition may further increase morbidity, mortality and costs in the post-transplantation setting. The importance of carefully assessing the nutritional status during the work-up of patients who are candidates for liver replacement is widely recognized. The metabolic abnormalities induced by liver failure render the conventional assessment of nutritional status to be challenging. Preoperative loss of skeletal muscle mass, namely, sarcopenia, has a significant detrimental impact on post-transplant outcomes. It is essential to provide sufficient nutritional support during all phases of liver transplantation. Oral nutrition is preferred, but tube enteral nutrition may be required to provide the needed energy intake. Herein, the latest currently employed perioperative nutritional interventions in liver transplant recipients are thoroughly illustrated including synbiotics, micronutrients, branched-chain amino acid supplementation, immunonutrition formulas, fluid and electrolyte balance, the offering of nocturnal meals, dietary counselling, exercise and rehabilitation.

    Nutritional support plays an important role in the treatment of patients with burns. Due to the severe hypercatabolism that develops in these patients, oral support is insufficient in most cases, and this makes it essential to initiate artificial nutritional support (either enteral or parenteral). Enteral nutrition is more physiological than parenteral, and data exist which show that in patients with burns, enteral nutrition exercises a protective effect on the intestine and may even reduce the hypermetabolic response in these patients. The purpose of the study was to evaluate the effectiveness and tolerance of enteral nutritional support with a hypercaloric, hyperproteic diet with a high content of branched amino acids in the nutritional support of patients suffering from burns. The study included 12 patients (8 males and 4 females), admitted to the Burns Unit. Average age was 35 +/- 17 years (range: 21-85 years). The percentage of body surface affected by the burns was 10% in two cases, between 10-30% in three cases, between 30-50% in five cases and over 50% in two cases. Initiation of the enteral nutrition was between twenty-four hours and seven days after the burn. The patients were kept in the unit until they were discharged, and the average time spent in the unit was 31.5 days (range: 17-63 days). Total energetic requirements were calculated based on Harris-Benedict, with a variable aggression factor depending on the body surface burned, which varied from 2,000 and 4,000 cal day. Nitrogenous balance was determined on a daily basis, and plasmatic levels of total proteins, albumin and prealbumin on a weekly basis. There was a significant difference between the prealbumin values at the initiation and finalization of the enteral nutrition (9.6 +/- 2.24 mg/dl compared with 19.75 +/- 5.48 mg/dl; p diet was very good, and only mild complications such as diarrhoea developed in two patients. Enteral nutrition is a suitable nutritional support method for patients with

    Competitive diving involves grace, power, balance, and flexibility, which all require satisfying daily energy and nutrient needs. Divers are short, well-muscled, and lean, giving them a distinct biomechanical advantage. Although little diving-specific nutrition research on performance and health outcomes exists, there is concern that divers are excessively focused on body weight and composition, which may result in reduced dietary intake to achieve desired physique goals. This will result in low energy availability, which may have a negative impact on their power-to-weight ratio and health risks. Evidence is increasing that restrictive dietary practices leading to low energy availability also result in micronutrient deficiencies, premature fatigue, frequent injuries, and poor athletic performance. On the basis of daily training demands, estimated energy requirements for male and female divers are 3,500 kcal and 2,650 kcal, respectively. Divers should consume a diet that provides 3-8 g/kg/day of carbohydrate, with the higher values accommodating growth and development. Total daily protein intake (1.2-1.7 g/kg) should be spread evenly throughout the day in 20 to 30 g amounts and timed appropriately after training sessions. Divers should consume nutrient-dense foods and fluids and, with medical supervision, certain dietary supplements (i.e., calcium and iron) may be advisable. Although sweat loss during indoor training is relatively low, divers should follow appropriate fluid-intake strategies to accommodate anticipated sweat losses in hot and humid outdoor settings. A multidisciplinary sports medicine team should be integral to the daily training environment, and suitable foods and fluids should be made available during prolonged practices and competitions.

    We examine the link between maternal nutrition knowledge and nutritional outcomes of children and adolescents (5-18 years) measured in terms of height-for-age Z-scores (HAZ). One particular focus is on the role of different types of nutrition knowledge. The analysis builds on household-level and individual-level data collected in urban Kenya in 2012 and 2015. Various regression models are developed and estimated. Results show that maternal nutrition knowledge - measured through an aggregate knowledge score - is positively associated with child HAZ, even after controlling for other influencing factors such as household living standard and general maternal education. However, disaggregation by type of knowledge reveals important differences. Maternal knowledge about food ingredients only has a weak positive association with child HAZ. For maternal knowledge about specific dietary recommendations, no significant association is detected. The strongest positive association with child HAZ is found for maternal knowledge about the health consequences of not following recommended dietary practices. These findings have direct relevance for nutrition and health policies, especially for designing the contents of educational campaigns and training programs. Copyright © 2017 Elsevier Ltd.

    2011-09-01

    Nowadays, there is an increasing quest for beauty and the models proposed by fashion goods and service segments, to achieve the perfect body. The standard of beauty corresponds to a thin body, without considering health aspects. The number of women who go on diets to control weight is increasing; and taking this into consideration the objective of this study is to conduct a bibliographical review and extract data on esthetics and body image to support the practice of nutritional care. Socio-cultural aspects, which motivate the quest for the perfect body, as well as body, beauty, esthetics, nutritional counseling and cognitive behavior therapy were examined in this survey. On the basis of this work, it is possible to conclude that the continuing obsession with the body may lead the person to go on diets and other drastic methods to control weight, such as surgical procedures. In this respect, nutritional care is far more than merely recommending a standard diet or giving information, as it represents providing an effective model for nutritional reeducation, prioritizing improvement in the style and quality of life. This article provides data about enhancing esthetics and beauty by means of appropriate nutrition.

    The efficacy of enteral nutrition in postoperative nutritional management is known, but the effects on gastrointestinal motility and nutrition have not yet been elucidated. The purpose of this study was to compare the effects of enteral and parenteral nutrition soon after open abdominal surgery on gastrointestinal motility and nutritional status. A partial resection of rectum models was prepared to compare two types of nutrient administration: enteral nutrition and total parenteral nutrition. The differences between the effects of nutrition types in terms of gastrointestinal motility and nutritional status were investigated. Enteral nutrition contributed to recovery of gastrointestinal motility and maintenance of nutritional status. Enteral nutrition should therefore be initiated soon after surgery if the gastrointestinal tract is available.

    Adequate nutrition is critical for maintenance of crew health during and after extended-duration space flight. The impact of weightlessness on human physiology is profound, with effects on many systems related to nutrition, including bone, muscle, hematology, fluid and electrolyte regulation. Additionally, we have much to learn regarding the impact of weightlessness on absorption, mtabolism , and excretion of nutrients, and this will ultimately determine the nutrient requirements for extended-duration space flight. Existing nutritional requirements for extended-duration space flight have been formulated based on limited flight research, and extrapolation from ground-based research. NASA's Nutritional Biochemistry Laboratory is charged with defining the nutritional requirements for space flight. This is accomplished through both operational and research projects. A nutritional status assessment program is included operationally for all International Space Station astronauts. This medical requirement includes biochemical and dietary assessments, and is completed before, during, and after the missions. This program will provide information about crew health and nutritional status, and will also provide assessments of countermeasure efficacy. Ongoing research projects include studies of calcium and bone metabolism, and iron absorption and metabolism. The calcium studies include measurements of endocrine regulation of calcium homeostasis, biochemical marker of bone metabolism, and tracer kinetic studies of calcium movement in the body. These calcium kinetic studies allow for estimation of intestinal absorption, urinary excretion, and perhaps most importantly - deposition and resorption of calcium from bone. The Calcium Kinetics experiment is currently being prepared for flight on the Space Shuttle in 2001, and potentially for subsequent Shuttle and International Space Station missions. The iron study is intended to assess whether iron absorption is down-regulated dUl1ng

    The elderly constitute a population group with a high prevalence of non-communicable chronic diseases and high risk of malnutrition. The aim of this study was to identify factors associated to nutritional risk in free-living European elderly. The sample included 644 European citizens, free living in the community, aged 65 years or more. The sample was quota controlled for age groups (65-74, ≥75 years), gender (male/female) and living circumstances (living alone/with others). Logistic regression was performed to identify factors associated with nutritional risk. Several variables regarding socio-demographic characteristics, food choice, health status and the satisfaction with food-related life were included in the analysis. According to the recoded score of the 'Determine your nutritional health' (NSI checklist), 53% of the elderly were at nutritional risk. Nutritional risk was more likely to occur in elderly who considered that it was more important to choose foods 'easy to chew'; with lower average number of fruit and vegetables (F&V) intake episodes and lower score for general health. It was also found in non-married participants; those that did not identify changes in their appetite; and those that felt changes in health status. In this sample, the lowest nutritional risk was found for body mass index (BMI) around 18.5 kg/m(2). Country of residence, gender and age were not found to have a significant effect on nutritional risk. Attention should be drawn to the living circumstances, changes in appetite or health, the general heath perception, F&V intake, choice of foods easy to chew and having a low or high BMI.

    Full Text Available Microglia are the essential responders to alimentary, pharmacological and nanotechnological immunomodulators. These neural cells play multiple roles as surveyors, sculptors, and guardians of essential parts of complex neural circuitries. Microglia can play dual roles in the central nervous system; they can be deleterious and/or protective. The immunomodulatory effects of alimentary components, gut microbiota and nanotechnological products have been investigated in microglia at the single cell level and in vivo using intravital imaging approaches, and different biochemical assays. This review highlights some of the emerging questions and topics from studies involving alimentation, microbiota, nanotechnological products, and associated problems in this area of research. Some of the advantages and limitations of in vitro and in vivo models used to study the neuromodulatory effects of these factors, as well as the merits and pitfalls of intravital imaging modalities employed are presented.

    Nutrition status prior to surgery and nutrition rehabilitation after surgery can affect the morbidity and mortality of pediatric patients. A comprehensive approach to nutrition in pediatric surgical patients is important and includes preoperative assessment, perioperative nutrition considerations, and postoperative recovery. A thorough nutrition assessment to identify patients who are at nutrition risk prior to surgery is important so that the nutrition status can be optimized prior to the procedure to minimize suboptimal outcomes. Preoperative malnutrition is associated with increased complications and mean hospital days following surgery. Enteral and parenteral nutrition can be used in cases where food intake is inadequate to maintain and possibly improve nutrition status, especially in the 7-10 days prior to surgery. In the perioperative period, fasting should be limited to restricting solid foods and non-human milk 6 hours prior to the procedure and allowing clear liquids until 2 hours prior to the procedure. Postoperatively, early feeding has been shown to resolve postoperative ileus earlier, decrease infection rates, promote wound healing, and reduce length of hospital stay. If nutrition cannot be provided orally, then nutrition through either enteral or parenteral means should be initiated within 24-48 hours of surgery. Practitioners should identify those patients who are at the highest nutrition risk for postsurgical complications and provide guidance for optimal nutrition during the perioperative and postoperative period. © 2015 American Society for Parenteral and Enteral Nutrition.

    2009-05-03

    Aetiology of inflammatory bowel disease (IBD) is complex and probably multifactorial. Nutrition has been proposed to be an important aetiological factor for development of IBD. Several components of the diet (such as sugar, fat, fibre, fruit and vegetable, protein, fast food, preservatives etc.) were examined as possible causative agents for IBD. According to some researchers infant feeding (breast feeding) may also contribute to the development of IBD. Though the importance of environmental factors is evidenced by the increasing incidence in developed countries and in migrant population in recent decades, the aetiology of IBD remained unclear. There are many theories, but as yet no dietary approaches have been proved to reduce the risk of developing IBD. The role of nutrition in the management of IBD is better understood. The prevention and correction of malnutrition, the provision of macro- and micronutrients and vitamins and the promotion of optimal growth and development of children are key points of nutritional therapy. In active disease, the effective support of energy and nutrients is a very important part of the therapy. Natural and artificial nutrition or the combination of two can be chosen for supporting therapy of IBD. The author summarises the aetiological and therapeutic role of nutrition in IBD.

    Inflammatory bowel disease (IBD) is a chronic pathology that has an outbreaks course that in recent years have seen an increase in incidence, especially at younger ages. Malnutrition is frequently associated with this condition, therefore, it is very important to ensure a right nutritional intervention, especially in pediatric patients, to ensure an optimal growth and also an improvement in the clinic. Our goal will be updated the role of nutrition in this disease and in its treatment based on the published evidence. Malnutrition in these patients is frequent and is influenced by various factors such as, decreased food intake, increased nutrient requirements, increased protein loss and malabsorption of nutrients. Therefore there should be a nutritional monitoring of all of them, in which anthropometric measurements, laboratory tests and densitometry were made to establish the needs and sufficient caloric intake tailored to each patient. The use of enteral nutrition as a treatment in Crohn’s disease with mild to moderate outbreak in child population, is amply demonstrated, has even shown to be superior to the use of corticosteroids. Therefore we can conclude by stressing that nutritional intervention is a mainstay in the management of patients with IBD, which aims to prevent and / or control disease-related malnutrition to decrease morbidity and mortality and improve quality of life.

    Midorikawa, Y.; Fujii, T.; Ohira, A.; Nitta, K.

    At the 40th IAF Congress in Malaga, a nutrition system for a lunar base CELSS was presented. A lunar base with a total of eight crew members was envisaged. In this paper, four species of plants—rice, soybean, lettuce and strawberry—were introduced to the system. These plants were sufficient to satisfy fundamental nutritional needs of the crew members. The supply of nutrition from plants and the human nutritional requirements could almost be balanced. Our study revealed that the necessary plant cultivation area per crew member would be nearly 40 m 3 in the lunar base. The sources of nutrition considered in the study were energy, sugar, fat, amino acids, inorganic salt and vitamins; however, calcium, vitamin B 2, vitamin A and sodium were found to be lacking. Therefore, a subsystem to supply these elements is of considerable value. In this paper, we report on a study for breeding snails and utilizing meat as food. Nutrients supplied from snails are shown to compensate for the abovementioned lacking elements. We evaluate the snail breeder and the associated food supply system as a subsystem of closed ecological life support system.

    Shea, Thomas B; Remington, Ruth

    2015-03-01

    Evidence for the benefit of nutrition in Alzheimer's disease continues to accumulate. Many studies with individual vitamins or supplements show marginal, if any, benefit. However, new findings with combinatorial formulations demonstrate improvement in cognitive performance and behavioral difficulties that accompany Alzheimer's disease. Herein, we review some of the most recent clinical advances and summarize supportive preclinical studies. We present novel positive effects on Alzheimer's disease derived from diet, trace elements, vitamins and supplements. We discuss the inherent difficulty in conducting nutritional studies because of the variance in participants' nutritional history, versus pharmacological interventions in which participants are naive to the intervention. We examine the evidence that epigenetics play a role in Alzheimer's disease and how nutritional intervention can modify the key epigenetic events to maintain or improve cognitive performance. Overall consideration of the most recent collective evidence suggests that the optimal approach for Alzheimer's disease would seem to combine early, multicomponent nutritional approaches (a Mediterranean-style diet, multivitamins and key combinatorial supplements), along with lifestyle modifications such as social activity and mental and physical exercise, with ultimate addition of pharmacological agents when warranted.

  16. Aging, Nutritional Status and Health

    Directory of Open Access Journals (Sweden)

    Full Text Available The older population is increasing worldwide and in many countries older people will outnumber younger people in the near future. This projected growth in the older population has the potential to place significant burdens on healthcare and support services. Meeting the diet and nutrition needs of older people is therefore crucial for the maintenance of health, functional independence and quality of life. While many older adults remain healthy and eat well those in poorer health may experience difficulties in meeting their nutritional needs. Malnutrition, encompassing both under and over nutrition increases health risks in the older population. More recently the increase in obesity, and in turn the incidence of chronic disease in older adults, now justifies weight management interventions in obese older adults. This growing population group is becoming increasingly diverse in their nutritional requirements. Micro-nutrient status may fluctuate and shortfalls in vitamin D, iron and a number of other nutrients are relatively common and can impact on well-being and quality of life. Aging presents a number of challenges for the maintenance of good nutritional health in older adults.

    Nutrition labelling on food packages becomes more and more widespread in the European Union. Such information is not compulsory, unless a nutrition or health claim is made. However, how do consumers use nutrition information? Two European studies are currently assessing whether nutrition...... information on food labels is exerting an effect on healthy food choices among consumers. Based for the first time on in-store observations and interviews, these studies give a real-life insight into consumers' shopping behaviours. The major outcomes to date are that most European consumers have reasonable...... knowledge about nutrition and are able to use nutrition labels to identify healthier products within a category....

    2010-01-01

    Normal functioning of the human body requires a balance between nutritional intake and metabolism, and imbalances manifest as nutritional deficiencies or excess. Nutritional deficiency states are associated with social factors (war, poverty, famine, and food fads), medical illnesses with malabsorption (such as Crohn disease, cystic fibrosis, and after bariatric surgery), psychiatric illnesses (eating disorders, autism, alcoholism), and medications. Nutritional excess states result from inadvertent or intentional excessive intake. Cutaneous manifestations of nutritional imbalance can herald other systemic manifestations. This contribution discusses nutritional deficiency and excess syndromes with cutaneous manifestations of particular interest to clinical dermatologists. Copyright © 2010. Published by Elsevier Inc.

    The effects of total fasting for 31 +/- 10 days followed by re-alimentation with an 800 calorie diet on thyroid function, i.e. T4,T3,rT3,RT3U (resin T3 uptake), and TSH, and on TBG levels in serum were studied sequentially in obese hospitalized patients (N=18). Additionally, cortisol, growth hormone, prolactin, parathyrin and free fatty acids were followed as hormonal and metabolic parameters, respectively. Further, CBG, transferrin, alpha 2-haptoglobin and complement C'3 were measured as representatives of other serum proteins. Results before fasting: T4, T3, TBG, cortisol, CBG, alpha 2-haptoglobin and complement C'3 of the obese patients were elevated when compared with healthy normal weight controls, whereas rT3, T4/TBG ratio, T3/TBG ratio, TSH, coritsol/cbg ratio, growth hormone, prolactin, parathyrin and transferrin of the obese group were normal. RT3U and fT4 index were decreased in the obese patients. Results during fasting: Significant decreases were observed during fasting for the following parameters -- T3, TBG, T3/TBG ratio, transferrin, alpha 2-haptoglobin complement C'3. rT3, T4/TBG ratio, RT3U, fT4 index and FFA increased. T4, tsh response to TRH stimulation, cortisol, CBG, cortisol/cbg ratio, parathyrin, growth hormone and prolactin did not change. Results during re-alimentation: T3, TBG, T3/TBG ratio, TSH response to TRH, transferrin, alpha 2-haptoglobin and complement C'3 increased. Conversely, fT3, RT3U, FFA, cortisol and cortisol/cbg ratio decreased whereas the other parameters did not change. 1) There is no evidence for primary hypothyroidism in obese patients during prolonged fasting and re-alimentation. 2) The rapid decrease of T3 and increase of RT3U after initiation of fasting are not fully explained by the observed slower decreases in TBG. 3) The alterations of T3, rT3 and RT3U resemble in their kinetics the changes in FFA levels. 4) Fasting reduced the levels of only certain serum proteins, interestingly TBG, transferrin, alpha 2

  1. Nutritional Supplements for Endurance Athletes

    Science.gov (United States)

    Rasmussen, Christopher J.

    Athletes engaged in heavy endurance training often seek additional nutritional strategies to help maximize performance. Specific nutritional supplements exist to combat certain factors that limit performance beginning with a sound everyday diet. Research has further demonstrated that safe, effective, legal supplements are in fact available for today's endurance athletes. Several of these supplements are marketed not only to aid performance but also to combat the immunosuppressive effects of intense endurance training. It is imperative for each athlete to research the legality of certain supplements for their specific sport or event. Once the legality has been established, it is often up to each individual athlete to decipher the ethics involved with ingesting nutritional supplements with the sole intent of improving performance.

    With a view to improve animal nutrition, studies have been carried out on the utilization of animal feeds using radioisotopes. Improvement of the nutritive value of straws, digestibility and VFA production by alkali treatment and other treatments has been studied by injecting VFA labelled with C 14 and H 3 . Microbial protein synthesis rates in ruminants were studied using C 14 and S 35 labelled mixed culture of bacterial protozca. Results obtained are helpful in understanding the metabolism in rumens and the microbial proteins available to the host animals on various dietary regimen. (A.K.)

    A review of the following points was performed: Factors favouring the development and presence of malnutrition among hospitalized patients. Useful parameters in nutritional evaluation. Types of malnutrition. The Chang nutritional evaluation protocol is used in our Hospital, which is simple, inexpensive, reliable, specific and easily reproduced. This is based on five variables (three anthropometric and two biochemical), randomized and based on reference tables and values. A study was made on data corresponding to 70 patients, in whom a prevalence of malnutrition was observed in critical patients. The patients were classified based on three different definitive possibilities (Marasmo, Kwashiorkor and combined), and three grades of malnutrition (slight, moderate and severe).

    Gunst, Jan; Van den Berghe, Greet

    2017-04-01

    Feeding guidelines have recommended early, full nutritional support in critically ill patients to prevent hypercatabolism and muscle weakness. Early enteral nutrition was suggested to be superior to early parenteral nutrition. When enteral nutrition fails to meet nutritional target, it was recommended to administer supplemental parenteral nutrition, albeit with a varying starting point. Sufficient amounts of amino acids were recommended, with addition of glutamine in subgroups. Recently, several large randomized controlled trials (RCTs) have yielded important new insights. This review summarizes recent evidence with regard to the indication, timing, and dosing of parenteral nutrition in critically ill patients. One large RCT revealed no difference between early enteral nutrition and early parenteral nutrition. Two large multicenter RCTs showed harm by early supplementation of insufficient enteral nutrition with parenteral nutrition, which could be explained by feeding-induced suppression of autophagy. Several RCTs found either no benefit or harm with a higher amino acid or caloric intake, as well as harm by administration of glutamine. Although unanswered questions remain, current evidence supports accepting low macronutrient intake during the acute phase of critical illness and does not support use of early parenteral nutrition. The timing when parenteral nutrition can be initiated safely and effectively is unclear.

    Weight loss and muscle wasting are commonly found in patients with end-stage liver disease. Since there is an association between malnutrition and poor clinical outcome, such patients (or those at risk of becoming malnourished) are often given parenteral nutrition, enteral nutrition, or oral nutritional supplements. These interventions have costs and adverse effects, so it is important to prove that their use results in improved morbidity or mortality, or both. To assess the beneficial and harmful effects of parenteral nutrition, enteral nutrition, and oral nutritional supplements on the mortality and morbidity of patients with underlying liver disease. The following computerised databases were searched: the Cochrane Hepato-Biliary Group Controlled Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE, EMBASE, and Science Citation Index Expanded (January 2012). In addition, reference lists of identified trials and review articles and Clinicaltrials.gov were searched. Trials identified in a previous systematic handsearch of Index Medicus were also considered. Handsearches of a number of medical journals, including abstracts from annual meetings, were done. Experts in the field and manufacturers of nutrient formulations were contacted for potential references. Randomised clinical trials (parallel or cross-over design) comparing groups of patients with any underlying liver disease who received, or did not receive, enteral or parenteral nutrition or oral nutritional supplements were identified without restriction on date, language, or publication status. Six categories of trials were separately considered: medical or surgical patients receiving parenteral nutrition, enteral nutrition, or supplements. The following data were sought in each report: date of publication; geographical location; inclusion and exclusion criteria; the type of nutritional support and constitution of the nutrient formulation; duration of
