Full Text Available Un estudio reciente destacó la presencia de Granulicatella spp. en episodios de bacteriemia en pacientes neutropénicos, a diferencia de Abiotrophia defectiva, que sólo se había observado en endocarditis infecciosa. El objetivo de esta presentación es describir un caso de bacteriemia por A. defectiva en un niño leucémico, neutropénico (200 GB/mm³ y febril (40 °C. En una de las muestras de hemocultivo se obtuvo el desarrollo de A. defectiva. A pesar de que el paciente estudiado cursaba una varicela, lo que podría justificar el episodio febril, el hallazgo de A. defectiva en el hemocultivo se interpretó como perteneciente a una bacteriemia verdadera ya que esta especie, según nuestros conocimientos, no forma parte de la flora habitual de la piel. Este caso sugiere que A. defectiva también puede ser responsable de casos de bacteriemia en pacientes inmunocomprometidos.The presence of Granulicatella spp. in bacteremic episodes of neutropenic patients was recently highlighted whereas Abiotrophia defectiva, was only isolated in cases of infectious endocarditis. The aim of this study is to describe a case of A.defectiva bacteremia in a leukemic and febrile (40 °C neutropenic (200 GB/mm³ boy. A.defectiva was only isolated from one of the two processed blood samples . Although the patient was undergoing an episode of varicela which could have accounted as the possible cause of fever, A. defectiva was considered a significant finding because this species is not part of the commensal skin flora. This case suggests that both A. defectiva and Granulicatella spp. should be regarded as possible causes of bacteremia in immunocompromised patients.

Full Text Available OBJECTIVE: The aim of this randomized clinical trial was to evaluate the frequency of bacteriemia during endodontic treatment, with comparison between two techniques for biomechanical preparation of the root canal system. MATERIALS AND METHODS: The sample comprised 50 patients aged 16 to 52 years, of both genders, which were divided into 2 groups with 25 patients each. Group I underwent biomechanical preparation by the step-back technique, and Group II was treated by the rotary technique with nickel-titanium instruments (K3. Patients were submitted to antisepsis of the oral cavity with chlorhexidine digluconate and three samples of blood were collected for blood culture: preoperatively, immediately after the biomechanical preparation and 10 minutes later. The significance level adopted was 5.0%, and analysis was performed by descriptive and inferential statistics by means of the Fisher's exact test, Fisher-Freeman-Halton test and Student's t test. Data were analyzed on the Statexact and SPSS softwares. RESULTS: All blood cultures achieved before and immediately after preparation were negative. On the other hand, with regard to the blood cultures collected 10 minutes after preparation, one (4% positive case was found for Group I. However, this difference was not statistically significant (p = 0.50.

Full Text Available BACKGROUND Nutrients form the fuel for the body, which comes in the form of carbohydrates, proteins and lipids. The body is intended to burn fuels in order to perform work. Starvation with malnutrition affects the postoperative patients and patients with acute pancreatitis. There is an increased risk of nosocomial infections and a delay in the wound healing may be noted. They are more prone for respiratory tract infections. Enteral Nutrition (EN delivers nutrition to the body through gastrointestinal tract. This also includes the oral feeding. This study will review the administration, rationale and assess the pros and cons associated with the early initiation of enteral feeding. The aim of this study is to evaluate if early commencement of enteral nutrition compared to traditional management (delayed enteral feeding is associated with fewer complications and improved outcome-  In patients undergoing elective/emergency gastrointestinal surgery.  In patients with acute pancreatitis. It is also used to determine whether a period of starvation (nil by mouth after gastrointestinal surgery or in the early days of acute pancreatitis is beneficial in terms of specific outcomes. MATERIALS AND METHODS A prospective cohort interventional study was conducted using 100 patients from July 2012 to November 2012. Patients satisfying the inclusion and exclusion criteria were included in the study. Patients admitted in my unit for GIT surgeries or acute pancreatitis constituted the test group, while patients admitted in other units for similar disease processes constituted the control group. RESULTS Our study concluded that early enteral feeding resulted in reduced incidence of surgical site infections. When the decreased length of stay, shorter convalescent period and the lesser post-interventional fatigue were taken into account, early enteral feeding has a definite cost benefit.CONCLUSION Early enteral feeding was beneficial associated with fewer

Full Text Available Patient care in an intensive care unit (ICU is associated with an increased risk of developing nosocomial infections. Bacteremia is responsible for a great number of cases, 23% of which have attributable mortality in developed countries and can affect up to 52% of ICU patients. The main cause of mortality is inadequate and inappropriate antimicrobial empirical therapy. The incorrect use of antimicrobials is a major risk for identifying multidrug resistant microorganisms, thereby involving increased morbidity, mortality and costs. Implementing several surveillance systems and becoming acquainted with resistance patterns represent a valuable tool for identifying, preventing and treating this infectious complication. There is paucity of data regarding antimicrobial resistance in bacteremic patients in Latin America, and the available data reveals a worrying scenario.El manejo médico en la unidad de cuidado intensivo (UCI se asocia con un mayor riesgo de infecciones intrahospitalarias. Las bacteriemias tienen una alta frecuencia en dichas unidades, se presentan hasta en el 52% de los pacientes allí asistidos y en los países desarrollados se les atribuye una mortalidad del 23%, que se debe fundamentalmente al uso de tratamiento empírico inadecuado o inapropiado. El uso incorrecto de los antimicrobianos es uno de los principales factores de riesgo para el desarrollo de la resistencia bacteriana, que conlleva la selección de microorganismos multirresistentes, el aumento de la morbilidad y la mortalidad y el incremento en los días de estancia hospitalaria y del costo por hospitalización. La implementación de diferentes sistemas de vigilancia y el conocimiento de la variabilidad en la resistencia a los antimicrobianos constituyen valiosas herramientas para identificar y prevenir la resistencia a los antibióticos y para orientar la terapéutica. En América Latina disponemos de pocos datos sobre las tasas de resistencia y aquellos disponibles

Full Text Available Vibrio cholerae no-O1, no-O139 es un agente poco frecuente como causal de bacteriemias y no hay informes que documenten su presencia en pacientes en hemodiálisis crónica. Se describe el caso de una paciente en hemodiálisis crónica que presentó un cuadro de sepsis, por lo cual inició un tratamiento con vancomicina y ceftacidima. Al cabo de seis horas y media de incubación en el sistema BACT/ALERT de hemocultivo, se evidenció la presencia de bacilos curvos gram negativos, posteriormente identificados como Vibrio cholerae mediante pruebas bioquímicas convencionales y el uso de los kits API 20 NE y VITEK 2. La evaluación del serogrupo y de la presencia de factores de patogenicidad, realizada en el laboratorio de referencia, determinó que el microorganismo hallado pertenecía al serogrupo no-O1, no-O139. No se detectó la toxina de cólera, tampoco el factor de colonización ni la toxina termoestable. El aislamiento presentó sensibilidad frente a ampicilina, trimetoprima-sulfametoxazol, ciprofloxacina, tetraciclina, ceftacidima y cefotaxima por el método de difusión con discos y por VITEK 2. La paciente cumplió 14 días de tratamiento con ceftacidima endovenosa, con evolución favorable.Non-O1, and non-O139 Vibrio cholerae is an infrequent cause of bacteremia. There are no reports of such bacteremia in chronic hemodialysis patients. This work describes the case of a chronic hemodialysis patient that had an episode of septicemia associated with dialysis. Blood cultures were obtained and treatment was begun with vancomycin and ceftazidime. After 6.5 hours of incubation in the Bact/Alert system there is evidence of gram-negative curved bacilli that were identified as Vibrio cholerae by conventional biochemical tests, API 20 NE and the VITEK 2 system. This microorganism was sent to the reference laboratory for evaluation of serogroup and virulence factors and was identified as belonging to the non-O1 and non-O139 serogroup. The cholera

Full Text Available Objective. This study aimed to determine the use of fecal elastase in evaluating the effect of simultaneous pancreas–kidney transplantation with enteric drainage on the pancreatic exocrine function of diabetic patients with uremia. Methods. A total of 19 patients with simultaneous pancreas–kidney transplantation (SPK with enteric drainage, 31 diabetic patients with uremia (chronic renal failure (CRF, 22 diabetic patients with uremia who underwent renal transplantation (RT, and 20 normal individuals (CON were included in the study. Pancreatic exocrine insufficiency was determined using fecal elastase. Results. The fecal pancreatic elastase level in SPK patients with enteric drainage was 479 μg/g, which was significantly higher than 229 μg/g in CRF patients and 197 μg/g in RT patients. Using 200 μg/g as the established threshold, a reduced fecal pancreatic elastase level was found in 14/31 of CRF patients, 12/22 of RT patients, 1/19 of SPK patients with enteric drainage, and 1/20 of CON patients. The correlation analysis revealed a significant association between fecal elastase and glycosylated hemoglobin. Conclusions. The present study indicated that SPK with enteric drainage improves pancreatic endocrine and exocrine functions. Fecal elastase may be a clinically relevant means to determine the therapeutic effects.

En el sellado del catéter venoso central en hemodiálisis, ¿presenta el uso de citrato respecto al uso de heparina menos complicaciones de infección? Una revisión de la literatura

Directory of Open Access Journals (Sweden)

Mateu Nadal Servera

Full Text Available Resumen Introducción: La heparina es el fármaco anticoagulante de elección y de uso habitual en los servicios de hemodiálisis, en el procedimiento de permeabilización de los catéteres venosos centrales, aunque su uso no está exento de riesgos como la hemorragia. La infección asociada al catéter, bien por colonización del catéter o por bacteriemia, es el evento más importante y la segunda causa de mortalidad tras la enfermedad cardiovascular en el paciente en hemodiálisis. En este sentido, el uso del citrato se está presentando como una alternativa para el sellado de los catéteres venosos centrales, dado que tiene propiedades tanto anticoagulantes locales como antimicrobianas y podría ser más eficiente en la prevención o la reducción de la infección asociada al catéter. Objetivos: Identificar qué anticoagulante de uso en el sellado del catéter venoso central, la heparina o el citrato, presenta menos complicaciones de bacteriemia asociada al catéter y de colonización del catéter; Material y Método: se realizó una búsqueda bibliográfica a través del metabuscador EBSCOhost (Academic Search Premier, CINAHL y las bases de datos PubMed, IME, Ibecs, LILACS, CUIDEN, Scopus y Cochrane Library, con la selección final de 15 documentos tras la aplicación de los límites de búsqueda, la eliminación de duplicados y la aplicación de los criterios de inclusión/exclusión. Los resultados más relevantes y actuales disponibles en la literatura científica presentaron cierta variabilidad, tanto en las concentraciones de anticoagulante como en la incidencia de infección. Resultados y Discusión: La numerosa evidencia sobre la bacteriemia asociada al catéter, tanto en relación con la concentración como en la combinación del anticoagulante de sellado, indica que el citrato 4% podría reducir la incidencia de bacteriemia, aunque el citrato asociado a antimicrobianos es más efectivo en la prevención de ésta respecto a la

Enteric inflammation models can help researchers' study methods to improve health and performance and evaluate various growth promoters and dietary formulations targeted to improve performance in poultry. Oral administration of fluorescein isothiocyanate-dextran (FITC-d; 3-5 kDa) and its pericellular mucosal epithelial leakage are an established marker to evaluate enteric inflammation in multiple species. The present study evaluated different methods to induce gut inflammation in poultry based on FITC-d leakage. Four independent experiments were completed with different inflammation treatment groups, and serum FITC-d and/or retention of FITC-d in GI tract were determined. In experiment 1 (n = 10 birds/treatment, broilers, processed at 14 days), groups included control (CON), dextran sodium sulfate (DSS; drinking water at 0.75%) and feed restriction (FRS; 24 h before processing). Experiment 2 (n = 14 birds/treatment, leghorns, processed at 7 days) included CON, DSS, FRS, and rye-based diet (RBD). In experiments 3 and 4 (n = 15 birds/treatment, broilers, processed at 7 days), groups were CON, DSS, high fat diet (HFD), FRS, and RBD. In all experiments, FRS and RBD treatments showed significantly higher serum FITC-d levels compared to the respective CON. This indicates that FRS and RBD results in disruption of the intact barrier of the gastrointestinal tract (GIT), resulting in increased gut permeability. DSS and HFD groups showed elevation of serum FITC-d levels although the magnitude of difference from respective CON was inconsistent between experiments. FRS was the only treatment which consistently showed elevated retention of FITC-d in GIT in all experiments. The results from present studies showed that FRS and RBD, based on serum FITC-d levels, can be robust models to induce gut leakage in birds in different age and species/strains.

The enteric nervous system is composed of both enteric neurones and enteric glia. Enteric glial cells were first described by Dogiel and are now known to outnumber neurones approximately 4 : 1. In the past, these cells were assumed to subserve a largely supportive role; however, recent evidence indicates that enteric glial cells may play a more active role in the control of gut function. In transgenic mouse models, where enteric glial cells are selectively ablated, the loss of glia results in intestinal inflammation and disruption of the epithelial barrier. Enteric glia are activated specifically by inflammatory insults and may contribute actively to inflammatory pathology via antigen presentation and cytokine synthesis. Enteric glia also express receptors for neurotransmitters and so may serve as intermediaries in enteric neurotransmission. Thus, enteric glia may serve as a link between the nervous and immune systems of the gut and may also have an important role in maintaining the integrity of the mucosal barrier and in other aspects of intestinal homeostasis.

Nutritional support in patients with severe acute pancreatitis Soporte nutricional en pacientes con pancreatitis aguda grave

Directory of Open Access Journals (Sweden)

Mónica Marcela Peláez Hernández

Full Text Available Severe acute pancreatitis is associated with a systemic inflammatory response leading to a hypermetabolic, hypercatabolic condition; for those reasons, patients suffering from this disease require an excellent artificial nutritional support in order to maintain the structural integrity and the function of vital organs with minimal pancreatic secretion. Total parenteral nutrition has been the standard practice in the treatment of patients with severe acute pancreatitis because of the favorable outcomes of early nutritional support while avoiding pancreatic stimulation; however, recent evidence suggests there are potentially greater benefits with enteral as compared with parenteral nutrition, including fewer septic and metabolic complications and lesser costs. That is why present guidelines for the management of acute pancreatitis recommend that enteral instead of parenteral nutrition be used in patients with severe acute pancreatitis. La pancreatitis aguda, especialmente en su forma grave, está asociada con una respuesta inflamatoria sistémica que lleva a un estado de hipermetabolismo e hipercatabolismo, en el que se requiere un excelente soporte nutricional que permita mantener la integridad estructural y la función de los órganos vitales con un estímulo mínimo de la secreción pancreática. La nutrición parenteral total era el soporte de elección, que permitía obtener todos los beneficios de la nutrición temprana sin estimular la secreción pancreática; pero la evidencia actual muestra mayores beneficios con la nutrición enteral, porque se asocia con menos complicaciones infecciosas y metabólicas y con disminución en los costos. Por ello las guías actuales de tratamiento de la pancreatitis aguda grave recomiendan como primera elección el soporte nutricional enteral.

2008-01-01

Radiotherapy of abdominal and pelvic tumours is frequently associated with acute radiation enteritis. Predominant symptoms include diarrhea, watery stools, abdominal pain, nausea and vomiting. There are very few effective interventions available for this condition. Enteral oligomeric nutrition has been used in bowel diseases with functional failure similar to radiation enteritis. The aim of presented work was to observe occurrence of symptoms of radiation enteritis in patients undergoing abdominal or pelvic radiotherapy. Apart from diet and pharmacological therapy, oral oligomeric enteral nutrition (Peptisorb Powder Nutricia) at the dose of 1000 - 2000 ml per day was administered for minimum of 4 days. Planned period of administration was 14 days and longer. Symptoms of radiation enteritis were evaluated at the beginning and in the end of administration. Prevalence of all evaluated symptoms of radiation enteritis was decreased and difference was statistically significant for diarrhea, watery stools, abdominal pain, nausea and vomiting. The use of evaluated oligomeric nutritional support might, in conjunction with pharmacotherapy and diet, alleviate symptoms of acute radiation enteritis and maintain nutritional status of patients.

Tea saponin is considered a promising natural compound for reducing enteric methane emissions in ruminants. A trial was conducted to study the effect of this plant extract fed alone or in combination with nitrate on methane emissions, total tract digestive processes, and ruminal characteristics in cattle. The experiment was conducted as a 2 × 2 factorial design with 4 ruminally cannulated nonlactating dairy cows. Feed offer was restricted to 90% of voluntary intake and diets consisted of (DM basis): 1) control (CON; 50% hay and 50% pelleted concentrates), 2) CON with 0.5% tea saponin (TEA), 3) CON with 2.3% nitrate (NIT), and 4) CON with 0.5% tea saponin and 2.3% nitrate (TEA+NIT). Tea saponin and nitrate were included in pelleted concentrates. Diets contained similar amounts of CP (12.2%), starch (26.0%), and NDF (40.1%). Experimental periods lasted 5 wk including 2 wk of measurement (wk 4 and 5), during which intake was measured daily. In wk 4, daily methane emissions were quantified for 4 d using open circuit respiratory chambers. In wk 5, total tract digestibility, N balance, and urinary excretion of purine derivatives were determined from total feces and urine collected separately for 6 d. Ruminal fermentation products and protozoa concentration were analyzed from samples taken after morning feeding for 2 nonconsecutive days in wk 5. Tea saponin and nitrate supplementation decreased feed intake ( saponin did not modify methane emissions (g/kg DMI; > 0.05), whereas nitrate-containing diets (NIT and TEA+NIT) decreased methanogenesis by 28%, on average ( saponin, whereas nitrate-containing diets increased acetate proportion and decreased butyrate proportion and ammonia concentration ( saponin alone included in pelleted concentrates failed to decrease enteric methane emissions in nonlactating dairy cows.

Enteric Duplication.

Jeziorczak, Paul M; Warner, Brad W

2018-03-01

Enteric duplications have been described throughout the entire gastrointestinal tract. The usual perinatal presentation is an abdominal mass. Duplications associated with the foregut have associated respiratory symptoms, whereas duplications in the midgut and hindgut can present with obstructive symptoms, perforation, nausea, emesis, hemorrhage, or be asymptomatic, and identified as an incidental finding. These are differentiated from other cystic lesions by the presence of a normal gastrointestinal mucosal epithelium. Enteric duplications are located on the mesenteric side of the native structures and are often singular with tubular or cystic characteristics. Management of enteric duplications often requires operative intervention with preservation of the native blood supply and intestine. These procedures are usually very well tolerated with low morbidity.

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)

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

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.

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.

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.

The enter-educate approach.

This article describes how the Population Communication Services (PCS) has seized on the "enter-educate" approach, the blending of popular entertainment with social messages, to change reproductive health behavior. The enter-educate approach spreads its message through songs, soap operas, variety shows, and other types of popular entertainment mediums. Because they entertain, enter-educate projects can capture the attention of an audience -- such as young people -- who would otherwise scorn social messages. And the use of population mediums makes it possible to reach a variety of audiences. Funded by USAID, PCS began its first enter-educate project in response to the increasing number of teenage pregnancies in Latin America. PCS developed 2 songs and videos, which featured popular teenage singers to serve as role models, to urge abstinence. The songs became instant hits. Since then, PCS has mounted more then 80 major projects in some 40 countries. Highlights of programs range from a successful multi-media family planning campaign in Turkey to humorous television ads in Brazil promoting vasectomy. Recently, PCS initiated projects to teach AIDS awareness. At the core of the enter-educate approach is the social learning theory which holds that much behavior is learned through the observation of role-models. Health professionals work alongside entertainers to produce works that have audience appeal and factual social messages. The enter-educate approach works because it is popular, pervasive, personal, persuasive, and profitable. PCS has found that enter-educate programs pay for themselves through cost sharing and cost recovery.

Meat-based enteral nutrition

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.

Although enteral nutrition (EN) therapy for Crohn's disease has been confirmed to be as effective as steroid therapy, the precise mechanism responsible for the effects of EN remains unclear, although some of the therapeutic effects of EN are believed to be due to a low dietary fat content. In order to elucidate the influence of fat in EN, it is important to investigate not only the quantity of fat, but also the source of the fat. We compared two enteral nutritional formulae: Elental (Ajinomoto) (elemental diet; ED), which contains only 1.5% fat, provided as long-chain triglycerides (LCT), versus Twinline (Snow Brand Milk Products) (TL), which contains a high percentage of fat (20.4%), provided mainly as medium-chain triglycerides (MCT). These formulae were tested on rat enteritis and rat colitis induced by trinitrobenzene sulfonic acid (TNBS). Both ED and TL reduced the manifestations of enteritis. TL had a stronger anti-inflammatory effect than ED for colitis. TL also had nutritional advantages as compared with ED, as shown by the total serum protein in the TL group being significantly higher than that in the ED group. The results indicate that intraluminal MCT is suitable as a fat energy source during intestinal inflammation in rats. We suggest that Twinline may be more useful to improve nutritional status and to reduce the mucosal inflammation in rat colitis, but that Twinline is equal in effect to Elental for rat enteritis.

Duck viral enteritis (DVE) outbreaks occurred at two different locations in Pennsylvania in 1991 and 1992. In the first outbreak, four ducks died out of a group of 30 domestic ducks; in the second outbreak, 65 ducks died out of a group of 114 domestic ducks, and 15 domestic geese died as well. A variety of species of ducks were present on both premises, but only muscovy ducks (Cairina moschata) died from the disease. On necropsy, gross lesions included hepatomegaly with petechial hemorrhages, petechial hemorrhages in the abdominal fat, petechial hemorrhages on the epicardial surface of the heart, and multifocal to coalescing areas of fibrinonecrotic material over the mucosal surface of the trachea, esophagus, intestine, and cloaca. Histologically, the liver had random multifocal areas of necrosis and eosinophilic intranuclear inclusion bodies in hepatocytes. DVE virus was isolated and identified using muscovy duck embryo fibroblast inoculation and virus neutralization. /// En dos sitios diferentes se presentaron brotes de enteritis viral de los patos en el estados de Pensilvania en los a??os 1991 y 1992.

The purpose of this document is to release, into the Hanford Document Control System, FA1/0991, Sludge Particle Separation Efficiencies for the Rectangular SCS-CON-230 Container, by M. Epstein and M. G. Plys, Fauske & Associates, LLC, June 2009. The Sludge Treatment Project (STP) will retrieve sludge from the 105-K West Integrated Water Treatment System (IWTS) Settler Tanks and transfer it to container SCS-CON-230 using the Settler Tank Retrieval System (STRS). The sludge will enter the container through two distributors. The container will have a filtration system that is designed to minimize the overflow of sludge fines from the container to the basin. FAI/09-91 was performed to quantify the effect of the STRS on sludge distribution inside of and overflow out of SCS-CON-230. Selected results of the analysis and a system description are discussed. The principal result of the analysis is that the STRS filtration system reduces the overflow of sludge from SCS-CON-230 to the basin by roughly a factor of 10. Some turbidity can be expected in the center bay where the container is located. The exact amount of overflow and subsequent turbidity is dependent on the density of the sludge (which will vary with location in the Settler Tanks) and the thermal gradient between the SCS-CON-230 and the basin. Attachment A presents the full analytical results. These results are applicable specifically to SCS-CON-230 and the STRS filtration system's expected operating duty cycles.

In this study, the intestinal endocrine cells were investigated in 13 surgical specimens affected by radiation enteritis. Endocrine cells were studied by means of Grimelius' silver staining and immunostaining for chromogranin, a general marker of endocrine cells. Positively stained cells were quantified by counting their number per unit length of muscularis mucosa. Results in radiation enteritis were compared with matched control specimens by using Student's t test. Chromogranin immunostaining showed a statistically significant increase of endocrine cells in radiation enteritis specimens compared with controls both in small and large intestine (ileum, 67.5 +/- 23.5 cells per unit length of muscularis mucosa in radiation enteritis versus 17.0 +/- 6.1 in controls; colon, 40.9 +/- 13.7 cells per unit length of muscularis mucosa in radiation enteritis versus 9.5 +/- 4.1 in controls--p less than 0.005 in both instances). Increase of endocrine cells was demonstrated also by Grimelius' staining; however, without reaching statistical significance. It is not clear whether or not the increase of endocrine cells in radiation enteritis reported in this study is caused by a hyperplastic response or by a sparing phenomenon. We should consider that increased endocrine cells, when abnormally secreting their products, may be involved in some of the clinical features of radiation enteropathy. In addition, as intestinal endocrine cells produce trophic substances to the intestine, their increase could be responsible for the raised risk of developing carcinoma of the intestine in long standing radiation enteritis

Diarrhea in enterally fed patients: blame the diet?

Diarrhea has great impact on enteral nutrition. The purpose of this review is to identify the factors leading to diarrhea during enteral nutrition and to provide the published updates on diarrhea prevention through nutritional intervention. Diarrhea in enteral fed patients is attributed to multiple factors, including medications (major contributor), infections, bacterial contamination, underlying disease, and enteral feeding. Diet management can alleviate diarrhea in enteral feeding. High content of fermentable oligosaccharides, disaccharides, and monosaccharides and polyols (FODMAPs) in enteral formula is postulated to induce diarrhea and lower FODMAPs formula may reduce the likelihood of diarrhea in enterally fed patients. Fiber-enriched formula can reduce the incidence of diarrhea and produce short-chain fatty acids for colonocytes. Ingesting prebiotics, nonviable probiotics or probiotic derivatives, and human lactoferrin may provide alternatives for reducing/preventing diarrhea. Enteral feeding is not generally considered the primary cause of diarrhea, which is frequently linked to prescribed medications. When diarrhea is apparent, healthcare members should evaluate the possible risk factors and systematically attempt to eliminate the underlying causes of diarrhea before reducing or suspending enteral feeding. Lower FODMAPs formula, prebiotics, probiotic derivatives, and lactoferrin may be used to manage enteral feeding-related diarrhea.

Do enteric neurons make hypocretin? ☆

Science.gov (United States)

Baumann, Christian R.; Clark, Erika L.; Pedersen, Nigel P.; Hecht, Jonathan L.; Scammell, Thomas E.

2008-01-01

Hypocretins (orexins) are wake-promoting neuropeptides produced by hypothalamic neurons. These hypocretin-producing cells are lost in people with narcolepsy, possibly due to an autoimmune attack. Prior studies described hypocretin neurons in the enteric nervous system, and these cells could be an additional target of an autoimmune process. We sought to determine whether enteric hypocretin neurons are lost in narcoleptic subjects. Even though we tried several methods (including whole mounts, sectioned tissue, pre-treatment of mice with colchicine, and the use of various primary antisera), we could not identify hypocretin-producing cells in enteric nervous tissue collected from mice or normal human subjects. These results raise doubts about whether enteric neurons produce hypocretin. PMID:18191238

Suplementación enteral con ácidos grasos esenciales en recién nacidos pretérmino

Full Text Available La tasa de crecimiento de recién nacidos (RN de muy bajo peso al nacer es muy elevada, sobre todo hasta que alcanzan el término y la ingesta balanceada de ácidos grasos esenciales es necesaria para un desarrollo adecuado de las membranas celulares fundamentalmente de cerebro y retina. Los tejidos de animales alargan y desaturan ácidos grasos progenitores, y esta conversión a ácidos grasos poliinsaturados de cadena larga se encuentra bajo regulación activa. En el RN pretérmino estos mecanismos son inmaduros y por tanto el ácido araquidónico y el docosahexaenoico se consideran esenciales, si se tiene en cuenta que el cerebro utiliza éstos como único perfil de ácidos grasos poliinsaturados de cadena larga. La fluidez de las membranas celulares dependerá del tipo de fosfolípido de las membranas y sobre todo de la longitud y saturación de la cadena acílica. La síntesis de prostaglandinas y tromboxanos en el RN pretérmino puede variar de acuerdo con la ingesta de ácido araquidónico. A pesar de que las necesidades de ácidos grasos esenciales están estimadas en unos pocos miligramos relacionados con la ingesta energética total, es preciso que exista una proporción adecuada entre el aporte de las 2 familias de ácidos grasos. La FAO/OMS y la ESPGAN han hecho recomendaciones para el aporte de ácido linoleico y a-linolénico en fórmulas infantiles para RN pretérmino, y mantienen una relación 5/15. En estos casos es necesaria también la suplementación con antioxidantes, para prevenir la peroxidación lipídica a la que están expuestos neonatos en oxígeno y con ventilación mecánica.The growth rate of very low birth weight newborn infants is considerably high, mainly until they reach the term, and a balanced intake of essential fatty acids is necessary for an adequate development of the cellular membranes fundamentally from the brain and retina.

To assess the effect of the addition of enteral tube feeding with polymeric diets to the standard treatment of acute attacks of inflammatory bowel disease a total of 43 patients admitted to hospital (23 with Crohn's disease and 20 with ulcerative colitis) were studied retrospectively. Total enteral nutrition was given to 26 as the sole nutritional supply and to 17 in conjunction with a normal ward diet, when appropriate, according to the severity of attack (control group). Nutritional state was assessed and classified in all patients at admission and at the end of the study, by measuring the triceps skinfold thickness, mid arm muscle circumference, and serum albumin concentration as representative of body fat, muscle protein, and visceral protein, respectively. At admission the three nutritional variables were not statistically different between the groups. There was a significantly positive effect on mid arm muscle circumference in patients on total enteral nutrition compared with the control group, but there was no effect on either triceps skinfold thickness or serum albumin concentration. The percentage of subjects requiring intravenous albumin infusion, however, was significantly less in the group fed enterally than in the control group. In addition, fewer patients in the group fed enterally required surgical treatment compared with the control group, despite the fact that one of the criteria for starting enteral nutritional support was the expectancy that surgery would be needed. Total enteral nutrition was well tolerated and no major side effects arose during its use in patients with acute exacerbations of inflammatory bowel disease. PMID:3098646

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

This study aimed to elucidate the mechanisms and kinetics of coating failure for enteric coated beads exposed to high-humidity conditions at different storage temperatures. Enteric coated beads were placed on high-humidity conditions (75 to 98% relative humidity (RH)) in the temperature range of 5 to 40°C. These stability samples of beads were tested for acid dissolution and water activity and also analyzed with SEM, X-ray CT, and DMA. Exposure of enteric coated beads to high humidity led to increased gastric release of drug which eventually failed the dissolution specification. SEM showed visible cracks on the surface of beads exposed to 5°C/high humidity and fusion of enteric beads into agglomerates at 40°C/high humidity. In a non-destructive time elapse study, X-ray CT demonstrated swelling of microcrystalline cellulose cores, crack initiation, and propagation through the API layer within days under 5°C/98% RH storage conditions and ultimately fracture through the enteric coating. DMA data showed a marked reduction in T g of the enteric coating materials after exposure to humidity. At 5°C/high humidity, the hygroscopic microcrystalline cellulose core absorbed moisture leading to core swelling and consequent fracture through the brittle API and enteric layers. At 40°C (high humidity) which is above the T g of the enteric polymer, enteric coated beads coalesced into agglomerates due to melt flow of the enteric coating. We believe it is the first report on two distinct failure models of enteric coated dosage forms.

The operative surgery used in these patients was gastrointestinal suture at any level and they were enterally fed. As soon as the intestinal dynamics was re-established, they were given enteral liquid feeding by continuos drip. This led to a reduction in parenteral nutrition, stay at hospital, parenteral nutrition complications, nosocomial infection complications from bacterial translocation, and in enteral inmunomodulation. In this way, quick recovery, improved weight gain, better quality of life, lower sequelae and mortality were reached, all of which resulted in lower costs.

A pesar de que estos microorganismos constituyen el tercer grupo de aislamientos obtenido de pacientes con bacteriemia o endocarditis, su interacción con la célula endotelial no se ha descrito completamente. En el presente trabajo evaluamos si el aislamiento intrahospitalario de Enterococcus faecalis (Ef2880 podía penetrar en células endoteliales de la vena de cordón umbilical humano (HUVEC cultivadas in vitro. Nuestros resultados indican que los cultivos primarios HUVEC después de ser inoculados con Ef2890, incubados y tratados con antibióticos bactericidas para las bacterias extracelulares y adheridas a la cara externa de la membrana celular, exhiben bacterias intracelulares que pueden ser recuperadas vivas cuatro horas después de la inoculación. El modelo biológico desarrollado se puede constituir en una herramienta útil para el estudio de las interacciones que establecen los enterococos con el endotelio.

To determine the prevalence of medical illness detected by laboratory screening in children entering foster care in a single, urban county. All children entering foster care in a single county in Ohio were seen at a consultation foster care clinic and had laboratory screening, including testing for infectious diseases such as HIV, hepatitis B, hepatitis C, syphilis, and tuberculosis as well as for hemoglobin and lead levels. Over a 3-year period (2012-2015), laboratory screening was performed on 1977 subjects entering foster care in a consultative foster care clinic. The prevalence of hepatitis B, hepatitis C, syphilis, and tuberculosis were all found to be <1%. There were no cases of HIV. Seven percent of teenagers entering foster care tested positive for Chlamydia . A secondary finding was that 54% of subjects were hepatitis B surface antibody-negative, indicating an absence of detected immunity to the hepatitis B virus. Routine laboratory screening for children entering foster care resulted in a low yield. Targeted, rather than routine, laboratory screening may be a more clinically meaningful approach for children entering foster care. Copyright © 2017 by the American Academy of Pediatrics.

Enteral feeding pumps: efficacy, safety, and patient acceptability

Full Text Available Helen White, Linsey King Nutrition and Dietetic Group, School of Health and Wellbeing, Faculty Health and Social Science, Leeds Metropolitan University, Leeds, United Kingdom Abstract: Enteral feeding is a long established practice across pediatric and adult populations, to enhance nutritional intake and prevent malnutrition. Despite recognition of the importance of nutrition within the modern health agenda, evaluation of the efficacy of how such feeds are delivered is more limited. The accuracy, safety, and consistency with which enteral feed pump systems dispense nutritional formulae are important determinants of their use and acceptability. Enteral feed pump safety has received increased interest in recent years as enteral pumps are used across hospital and home settings. Four areas of enteral feed pump safety have emerged: the consistent and accurate delivery of formula; the minimization of errors associated with tube misconnection; the impact of continuous feed delivery itself (via an enteral feed pump; and the chemical composition of the casing used in enteral feed pump manufacture. The daily use of pumps in delivery of enteral feeds in a home setting predominantly falls to the hands of parents and caregivers. Their understanding of the use and function of their pump is necessary to ensure appropriate, safe, and accurate delivery of enteral nutrition; their experience with this is important in informing clinicians and manufacturers of the emerging needs and requirements of this diverse patient population. The review highlights current practice and areas of concern and establishes our current knowledge in this field. Keywords: nutrition, perceptions, experience

Comparison of the EntericBio multiplex PCR system with routine culture for detection of bacterial enteric pathogens.

LENUS (Irish Health Repository)

O'Leary, James

2009-11-01

The EntericBio system uses a multiplex PCR assay for the simultaneous detection of Campylobacter spp., Salmonella enterica, Shigella spp., and Escherichia coli O157 from feces. It combines overnight broth enrichment with PCR amplification and detection by hybridization. An evaluation of this system was conducted by comparing the results obtained with the system with those obtained by routine culture, supplemented with alternative PCR detection methods. In a study of 773 samples, routine culture and the EntericBio system yielded 94.6 and 92.4% negative results, respectively. Forty-two samples had positive results by culture, and all of these were positive with the EntericBio system. This system detected an additional 17 positive samples (Campylobacter spp., n = 12; Shigella spp., n = 1; E. coli O157, n = 4), but the results for 5 samples (Campylobacter spp., n = 2; Shigella spp., n = 1; E. coli O157, n = 2) could not be confirmed. The target for Shigella spp. detected by the EntericBio system is the ipaH gene, and the molecular indication of the presence of Shigella spp. was investigated by sequence analysis, which confirmed that the ipaH gene was present in a Klebsiella pneumoniae isolate from the patient. The sensitivity, specificity, positive predictive value, and negative predictive value were 100%, 99.3%, 91.5%, and 100%, respectively. Turnaround times were significantly reduced with the EntericBio system, and a result was available between 24 and 32 h after receipt of the sample in the laboratory. In addition, the amount of laboratory waste was significantly reduced by use of this system. In summary, the EntericBio system proved convenient to use, more sensitive than the conventional culture used in this study, and highly specific; and it generated results significantly faster than routine culture for the pathogens tested.

Cellular changes in the enteric nervous system during ageing.

Science.gov (United States)

Saffrey, M Jill

2013-10-01

The intrinsic neurons of the gut, enteric neurons, have an essential role in gastrointestinal functions. The enteric nervous system is plastic and continues to undergo changes throughout life, as the gut grows and responds to dietary and other environmental changes. Detailed analysis of changes in the ENS during ageing suggests that enteric neurons are more vulnerable to age-related degeneration and cell death than neurons in other parts of the nervous system, although there is considerable variation in the extent and time course of age-related enteric neuronal loss reported in different studies. Specific neuronal subpopulations, particularly cholinergic myenteric neurons, may be more vulnerable than others to age-associated loss or damage. Enteric degeneration and other age-related neuronal changes may contribute to gastrointestinal dysfunction that is common in the elderly population. Evidence suggests that caloric restriction protects against age-associated loss of enteric neurons, but recent advances in the understanding of the effects of the microbiota and the complex interactions between enteric ganglion cells, mucosal immune system and intestinal epithelium indicate that other factors may well influence ageing of enteric neurons. Much remains to be understood about the mechanisms of neuronal loss and damage in the gut, although there is evidence that reactive oxygen species, neurotrophic factor dysregulation and/or activation of a senescence associated phenotype may be involved. To date, there is no evidence for ongoing neurogenesis that might replace dying neurons in the ageing gut, although small local sites of neurogenesis would be difficult to detect. Finally, despite the considerable evidence for enteric neurodegeneration during ageing, and evidence for some physiological changes in animal models, the ageing gut appears to maintain its function remarkably well in animals that exhibit major neuronal loss, indicating that the ENS has considerable

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.

Malnutrition in hospitalised patients has a significant and disadvantageous impact on treatment outcome. If possible, enteral nutrition with an energy/protein-balanced nutrient should be preferred depending on the patient's condition, type of illness and risk factors. The aim of the nutrition therapy is to increase the efficacy of treatment and shorten the length of hospital stay in order to ensure rapid rehabilitation. In the present review the authors summarize the most important clinical and practical aspects of enteral nutrition therapy.

Epigenetic regulation of enteric neurotransmission by gut bacteria.

2016-01-01

Full Text Available The Human Microbiome Project defined microbial community interactions with the human host, and provided important molecular insight into how epigenetic factors can influence intestinal ecosystems. Given physiological context, changes in gut microbial community structure are increasingly found to associate with alterations in enteric neurotransmission and disease. At present, it is not known whether shifts in microbial community dynamics represent cause or consequence of disease pathogenesis. The discovery of bacterial-derived neurotransmitters suggests further studies are needed to establish their role in enteric neuropathy. This mini-review highlights recent advances in bacterial communications to the autonomic nervous system and discusses emerging epigenetic data showing that diet, probiotic and antibiotic use may regulate enteric neurotransmission through modulation of microbial communities. Because of its limited scope, a particular emphasis is placed on bacterial regulation of enteric nervous system function in the intestine.

Osmolality and pH in handmade enteral diets used in domiciliary enteral nutritional therapy

Gilberto Simeone HENRIQUES

Full Text Available Abstract Patients who need prolonged domiciliary enteral nutritional therapy may benefit from handmade diets. However, the preparation of such diets might cause insecurity with regard to their nutritional composition and physical-chemical properties. Current study analyzes the osmolality and Hydrogen-Ion concentration (pH on handmade enteral diets. To this purpose, six formulas and two juices, prescribed on discharge from hospital, were analyzed physically and chemically. Osmolality and pH were respectively determined by cryoscopy and potentiometry. Most formulations were classified as isosmolar (with less than 400 mOsm/kg solvent, and only one was classified as slightly hyperosmolar, with rates ranging from 356.7 to 403.5 mOsm/kg solvent. On average, the standard formula presented higher osmolality than similar ones prepared for hyperglycemia. Among the juices, only one registered hyperosmolar concentration of 595.54 mOsm/kg solvent. All formulas presented pH rates classified as low acidity, ranging between 6.1 and 6.6, while the two juices had the lowest results, 4.73 and 4.66 each. The blend of ingredients used in handmade formulas and juices studied presented acceptable osmolality and pH rates for a safe administration and absence of gastrointestinal complications. Data showed here are consistent with an appropriate and healthy diet and contributed towards success in domiciliary enteral nutritional therapy.

Intestinal obstruction by eosinophilic jejunitis Aspectos quirúrgicos de la enteritis eosinofílica

Directory of Open Access Journals (Sweden)

2004-04-01

Full Text Available Eosinophilic enteritis is an uncommon disease that rarely devel-ops as a surgical emergency. Although it may be associated with infestation by Ancylostoma caninum, its etiology is unknown and often related to a personal or family history of atopy. A transmural involvement may cause intestinal obstruction -more frequently in the jejunum- or even acute abdomen, which may or may not be accompanied by intestinal perforation. The latter two conditions tend to be more commonly associated with ileum disease, causing pain in the lower right quadrant of the abdomen. Patient history, eosinophil count -which may be paradoxically reduced when the disease appears in this way-, ultrasonography, and/or CT lead to the suspicion of this condition before a surgical procedure is considered. A definitive diagnosis, however, must be reached by means of an anatomopathological study. Macroscopically, intestinal loops exhibit a thickened appearance with an elastic consistency. Laparoscopic intestinal biopsy may play a major role in the diagnosis of disease.La enteritis eosinofílica es una enfermedad poco frecuente que debuta de forma extraordinaria como urgencia quirúrgica. Su etiopatogenia, aunque pudiera estar asociada a la infestación por Ancylostoma caninum, se desconoce, y en muchas ocasiones se relaciona con antecedentes personales o familiares de atopia. La afectación transmural puede ocasionar síndrome obstructivo intestinal, más frecuente a nivel yeyunal, o incluso un abdomen agudo acompañado o no de perforación entérica. Estas dos últimas entidades suelen estar asociadas más usualmente con el asentamiento de la enfermedad en íleon, provocando dolor en la fosa iliaca derecha. Los antecedentes del enfermo, el recuento de eosinófilos en sangre, que paradójicamente puede estar disminuido cuando la enfermedad debuta de esta forma, la ecografía y/o la TAC, pueden hacernos sospechar de esta patología antes de plantearse la intervención quir

Radiation enteritis is a progressive, disease process that causes intestinal fibrosis and obliterative endarteritis, which results in significant morbidity and mortality. The authors' clinical experience involving 20 patients over a 22-year period from 1967 through 1989 who underwent various surgical procedures to alleviate chronic symptoms secondary to radiation enteritis is described. Eight men and 12 women with a mean age of 52 years (24 to 81 years) underwent a total of 27 procedures for complications of radiation enteritis. Radiation therapy was delivered for treatment of gynecologic malignancies (55%), colorectal cancer (20%), prostate malignancies (10%), and others (15%). The mean average dose of radiation delivered was 5,514 rads with a range of 2,613 to 7,000 rads. The interval from radiation treatment to time of surgery averaged 9 years. Operative procedures consisted of 12 resection and primary anastomosis procedures and 15 resections with stoma creation. Formation of a stoma was used in patients with more severe disease. The 30-day operative mortality was 0% and morbidity was 55%. There were no anastomotic leaks or intra-abdominal abscesses. The authors conclude that resection and primary anastomosis can safely be performed in selected patients but that judicious use of stoma formation can avoid major mortality and morbidity associated with surgery in this setting.

Radiation enteritis is a progressive, disease process that causes intestinal fibrosis and obliterative endarteritis, which results in significant morbidity and mortality. The authors' clinical experience involving 20 patients over a 22-year period from 1967 through 1989 who underwent various surgical procedures to alleviate chronic symptoms secondary to radiation enteritis is described. Eight men and 12 women with a mean age of 52 years (24 to 81 years) underwent a total of 27 procedures for complications of radiation enteritis.

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.

The enteric nervous system (ENS) arises from the coordinated migration, expansion and differentiation of vagal and sacral neural crest progenitor cells. During development, vagal neural crest cells enter the foregut and migrate in a rostro-to-caudal direction, colonizing the entire gastrointestinal tract and generating the majority of the ENS. Sacral neural crest contributes to a subset of enteric ganglia in the hindgut, colonizing the colon in a caudal-to-rostral wave. During this process, enteric neural crest-derived progenitors (ENPs) self-renew and begin expressing markers of neural and glial lineages as they populate the intestine. Our earlier work demonstrated that the transcription factor Foxd3 is required early in neural crest-derived progenitors for self-renewal, multipotency and establishment of multiple neural crest-derived cells and structures including the ENS. Here, we describe Foxd3 expression within the fetal and postnatal intestine: Foxd3 was strongly expressed in ENPs as they colonize the gastrointestinal tract and was progressively restricted to enteric glial cells. Using a novel Ednrb-iCre transgene to delete Foxd3 after vagal neural crest cells migrate into the midgut, we demonstrated a late temporal requirement for Foxd3 during ENS development. Lineage labeling of Ednrb-iCre expressing cells in Foxd3 mutant embryos revealed a reduction of ENPs throughout the gut and loss of Ednrb-iCre lineage cells in the distal colon. Although mutant mice were viable, defects in patterning and distribution of ENPs were associated with reduced proliferation and severe reduction of glial cells derived from the Ednrb-iCre lineage. Analyses of ENS-lineage and differentiation in mutant embryos suggested activation of a compensatory population of Foxd3-positive ENPs that did not express the Ednrb-iCre transgene. Our findings highlight the crucial roles played by Foxd3 during ENS development including progenitor proliferation, neural patterning, and glial

Objective: To compare neutral and positive enteral contrast media for MDCT enteroclysis (MDCTE) in various small bowel diseases. Materials and methods: 40 patients with suspicion of small bowel diseases were divided randomly into two equal groups. In one group, water was used as neutral enteral contrast and in other group, 2% water soluble iodinated contrast was used as positive enteral contrast. All MDCTE were done on a 16-slice multidetector row CT unit. The findings of MDCTE were compared with the standards of reference. Results: There were 12 cases of abdominal tuberculosis (30%), 5 cases of bowel masses (12%), 4 cases of Crohn's disease (10%), 3 cases of small bowel adhesions (7%), 2 cases of midgut volvulus (5%), 2 cases of segmental enteritis (5%) and 12 of all cases (30%) were normal. There was no statistically significant difference between neutral and positive enteral contrast with regards to bowel distention, contrast reflux and evaluation of duodenum. Abnormal bowel wall enhancement was appreciated only with use of neutral enteral contrast (n = 12). Evaluation of ileocaecal junction was possible in all 20 patients (100%) with positive enteral contrast but in only 17 patients (85%) with neutral enteral contrast. Overall sensitivity and specificity of MDCTE with use of neutral contrast medium (100 and 88% respectively) was greater for evaluation of small bowel diseases, when compared to MDCTE using positive enteral contrast medium (92.8 and 83.3% respectively). Conclusions: Water is a good enteral contrast medium for MDCT enteroclysis examination and allows better evaluation of abnormal bowel wall enhancement. Ileocaecal junction evaluation is better with positive enteral contrast medium.

[Enteral alimentation at home: why PEG now?].

Suzuki, Y; Hanyu, N; Kashiwagi, H; Kubo, T; Aoki, T

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.

The spectrum of radiation enteritis: surgical considerations

Haddad, G.K.; Grodsinsky, C.; Allen, H.

1983-01-01

Radiation therapy, often used to treat gynecologic and urologic pelvic malignancies, has varying, adverse effects on the bowel. Radiation enteritis may occur from one month to 20 years after irradiation, and disabling symptoms may require surgery in 10 to 20 per cent of patients. From our experience with 20 patients who required surgery for radiation enteritis and who were followed for up to 20 years, we were able to identify three clinical groups. Patients in the first group need only medical treatment for their symptoms, and observation, whereas patients in the second group may present with acute, debilitating, life-threatening symptoms that may require emergency surgery. Patients in the third group have a long-standing history of intermittent bowel obstruction and/or enteric fistulas that are best treated with adequate nutritional support followed by timely surgical intervention

To assess the value of enteral contrast media for the evaluation of pelvic masses by MR imaging. Between April and July 1998, 16 women with pelvic masses were examined by MRI. The origin of the lesion was the ovary in twelve cases, the uterus in three, and the sigmoid in one. Using a 1.5T scanner(Magnetom Vision, Siemens), T1-weighted axial spin echo(SE), T2-weighted turbo spin echo(TSE), two dimensional fast low-angle shot(FLASH 2D), and half-Fourier TSE(HASTE) images were obtained in all patients after the administration of Magnevist Enteral (Shering, Berlin, Germany). In each MR imagine sequence, distinction between the lesion and adjacent bowel (1, not distinguished; 2, partly distinguished; 3, clearly distinguished), artifact (0, absent; 1, mild; 2, severe), image quality (1, poor; 2, fair; 3, good), were compared before and after the use of enteral contrast media. Changes in MRI impression after the use of enteral contrast media were also evaluated. Two radiologists reached a consensus after reviewing the images. Statistical significance was determined by Wilcoxon's signed ranked test. For distinguishing lesions, SE T1WI and FLASH 2D with enteral contrast media were significantly superior to SE T1WI without enteral contrast media (p < 0.05). With regard to image quality, FLASH 2D and HASTE, both with enteral contrast media, were significantly superior to SE T1WI and TSE T2WI, respectively, both without enteral contrast media (p < 0.05). Artefacts were more frequently found after the application of enteral contrast media in conventional sequences but were not present in breathhold sequences. In two patients, MRI impression changed after the application of enteral contrast media. In a limited number of cases, enteral contrast media improved lesion detection, image quality and diagnostic accuracy when breathhold fast MR imaging was applied

Role of FODMAP content in enteral nutrition-associated diarrhea.

Science.gov (United States)

Halmos, Emma P

2013-12-01

Gastrointestinal symptoms including diarrhea are common complications of enteral nutrition (EN); however, the cause is unclear. Mode of EN delivery that alters digestion and possibly absorption is suggested to contribute to the high incidence of diarrhea; however, enteral formula is frequently blamed. Most research has focused on fiber-supplemented EN, with a meta-analysis showing that fiber reduces the incidence of diarrhea in non-intensive care unit studies. Other hypotheses include formula osmolality and FODMAP (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols) content. FODMAPs are poorly absorbed short-chain carbohydrates that exert an osmotic effect. Dietary FODMAPs have been shown to reduce gastrointestinal symptoms, including diarrhea, in those with irritable bowel syndrome and, given a high-enough dose, will induce a laxative effect in most people. As FODMAPs are commonly added to enteral formula and EN is frequently used as the main source of nutrition, it is reasonable to hypothesize that EN provides more FODMAPs than usual dietary intake and increases risk for developing diarrhea. This hypothesis was assessed through a retrospective study showing that the standard-use enteral formula Isosource 1.5 had a protective effect of developing diarrhea. The only characteristic unique to Isosource 1.5 was the lower FODMAP content as determined through methodologies previously validated for food analysis. Methodologies for application to enteral formulas are currently undergoing formal validation. Once confirmed for application in enteral formula, future directions include FODMAP analysis of specific ingredients to increase understanding of potential problems associated with enteral formula and a randomized, controlled trial investigating the role of formula FODMAP content. © 2013 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

Severe back pain a cirrhotic patient : a diagnostic challenge

2018-05-01

Full Text Available Spondylodiscitis is an infection of the intervertebral disc space, involves the vertebrae, causing vertebral osteomyelitis and spread to adjacent epidural space, causing dural, radicular or spinal cord compression. Appears mainly in adult and immunocompromised patients, mainly by haematogenous inoculation from systemic infections with bacteriemia. Patients with hepatic cirrhosis have frequent bacteriemias, produced by increased gut permeability, immune dysfunction and frequent need for invasive procedures. Despite high frequency of blood stream infections, discitis and vestebral osteomyelitis are rarely reported. We present the case of a 53 years old woman, diagnosed with class B Child Pugh cirrhosis, which presents with intense back pain and cauda equina syndrome, without clinical signs of infection. Diagnosis was confirmed by spinal MRI, but very soon after treatment onset, the patient suffered a septic shock with haemodynamic instability, which leads to patient’s death. This case illustrates how an unusual complication of cirrhosis – bacteriemia - could precipitate the unfavorable evolution of the patient by producing a remote septic complication. Persistent back pain in a cirrhotic patient should also raise the hypothesis of an infectious cause, in which early management is essential. Early diagnosis in essential for successful treatment, and good prognosis after long-term antibiotic treatment can be achieved in the majority of patients.

There is no internationally recognized case-definition for travel-associated enteric fever in non-endemic countries. This study describes the patterns of case reporting between 2007 and 2011 as travel-associated or not from the surveillance data in England, Wales and Northern Ireland (EWNI), before and after a change in the time component of the case-definition in January 2011. It examines in particular the role of a time frame based on the reported typical incubation period in defining a case of travel-associated enteric fever. The results showed no significant differences in the distribution of cases of enteric fever in regards to the interval between the onset and UK arrival in 2011 compared to 2007-2010 (p=0.98 for typhoid and paratyphoid A); the distribution for paratyphoid B was also similar in both time periods. During 2007-2010, 93% (1730/1853) of all of the cases were classified as travel-associated compared to 94% (448/477) in 2011. This difference was not statistically significant. Changing the time component of the definition of travel-associated enteric fever did not make a significant difference to the proportion of travel-associated cases reported by investigators. Our analysis suggests that time might be subordinate to other considerations when investigators classify a case as travel-associated. Crown Copyright © 2014. Published by Elsevier Ltd.

Radiation-induced enteritis is a serious clinical problem for which there is currently no recommended standard management. Daikenchuto (DKT) is a Japanese herbal medicine that has been used to treat adhesive bowel obstruction in Japan. This report describes a patient with radiation-induced enteritis whose clinical symptoms were much improved by treatment with DKT. The patient was administered DKT, a traditional Japanese herbal formula, orally (2.5 g 3 times daily). Abdominal distention was evaluated objectively with computed tomography. Gastrointestinal symptoms associated with radiation-induced enteritis were controlled successfully with DKT treatment. DKT treatment may be useful for the management of radiation-induced enteritis.

2010-06-01

Full Text Available Introduction: Extracorporeal shock wave lithotripsy (ESWL has produced a great revolution in the treatment of the urolithiasis. Bacteriemia, bacteriuria, and septic shock are the documented complaints for which early diagnosis and treatment can be vital. C-reactive protein (CRP, an acute phase reactant, serves as a marker of the infection before other measures. In this study, we measured the CRP value in the early detection of bacteriemia and bacteriuria after ESWL.Methods: In 2005, we sought patients who had urolithiasis and were candidates for ESWL, and we recruited such patients for this study. The inclusion criteria were sterile urine and a negative CRP test. The patients who participated in the study were requested to undergo laboratory tests on the third and seventh days after ESWL. After the resulting data were entered into the SPSS-11.5 data analysis software, the analyses were done with Chi squared test.Results: Among the studied subjects, 29 out of 97 (29.9% had a positive CRP test and 16 (15.2% had positive urine cultures. There was no significant statistical relationship between the CRP tests and the urine cultures (P value > 0.05. On the third day, the relationship between CRP and erythrocyte sedimentation rate (ESR was significant (P value < 0.001. The positive predictive values of CRP were 0.087 and 0.214, and the negative predictive values were 0.87 and 0.963. The sensitivity and specificity of CRP were 18.2% and 74.1% (first stage, respectively, and 60% and 82.5% (second stage, respectively.Conclusions: We were unable to determine what the diagnostic value of CRP should be in the early detection of infection after ESWL. Additional studies are needed to provide greater insight into this issue.

Enteric duplication cysts are rare and uncommon congenital malformations formed during the embryonic period of the development of human digestive system and are mainly encountered during infancy or early childhood, but seldom in adults. The clinical presentation is extremely variable depending upon its size, location and type. We present six cases of enteric duplication cysts with diverse clinico-pathological features. This study was carried out in the Department of Pathology and Department of Paediatric Surgery, Vardhman Mahavir Medical College and Safdarjung Hospital, New Delhi, India for a period of 2 years (January 2013 - December 2014). We retrospectively analyzed six patients of enteric duplication cysts based on data obtained, which consisted of patient's age, sex, clinical presentation, radiological features, operative findings and histopathology report. The data collected was analyzed by descriptive statistics. Six children between age range of 3 days to 10 years had enteric duplication cysts. Two had ileal and one each were of pyloroduodenal, colonic and rectal duplication cyst. In one patient a presumptive diagnosis of enteric duplication cyst was made. Radiology played an important contributory role in diagnosis of these cysts in all the patients but histopathology proved to be gold standard for its confirmation. All these patients were managed by surgical excision. The postoperative and follow up period in all the cases was uneventful. It is important to be aware and make a definitive diagnosis of this rare congenital anomaly as they can present in various clinical forms and can cause significant morbidity and even mortality if left untreated by causing life threatening complications.

It was performed a comprehensive experimental and clinical study of functional and metabolic status of the intestine in acute peritonitis, pancreatic necrosis, acute intestinal obstruction. We obtained objective data of impaired barrier function based on levels of toxins in arterial and mesenteric venous blood. Association of organ and organismic homeostatic changes was revealed. It was proved an important role of membrane-destabilizing processes in intestinal epithelium as a cause of enteral insufficiency. Leading trigger mechanisms of lipid metabolic disorders were determined. Enteral distress syndrome was determined as pathological response to acute abdominal surgical diseases. Enteral distress syndrome is a complex of pathological processes due to membrane-destabilizing mechanisms, impaired intestinal barrier function followed by progression of endogenous intoxication. This syndrome significantly aggravates the course of acute surgical abdominal diseases.

BACKGROUND Recent trials have shown controversial results on which enteral feeding methods has a lower risk of enteral feeding intolerance. Therefore, we aimed to compare two methods of bolus and intermittent feeding on enteral feeding intolerance of patients with sepsis. METHODS This triple-blind randomized controlled trial was conducted on 60 patients with sepsis, who were fed through tubes for at least 3 days. The patients were randomly assigned into bolus feeding, intermittent feeding, and control groups. Enteral feeding intolerance of all patients was recorded in 3 consecutive days by a researcher-made checklist including the data on gastric residual volume, vomiting, diarrhea, constipation, and abdominal distension. RESULTS There were no significant differences between the three studied groups in none of the intervention days pertaining to constipation, diarrhea, vomiting, abdominal distention, and gastric residual volume ( p > 0.05). Also, no statistically significant difference was found between all variables in the three studied groups during the 3 days ( p > 0.05). CONCLUSION As enteral feeding intolerance of patients with sepsis was similar in both bolus and intermittent feeding methods, it can be concluded that bolus method can still be used as a standard method to decrease the risk of enteral feeding intolerance if it is used properly.

Significant malnutrition exists in a high percentage of patients with gastric cancer. It is, therefore, crucial to establish an effective means to provide nutrition for these patients. This prospective, randomized, double-blinded clinical trial aims to assess the long-term survival of arginine-supplementation enteral nutrition versus standard enteral nutrition in malnourished patients with gastric cancer. The control group (36 cases) received postoperative standard enteral nutrition. Meanwhile, the arginine-supplementation group (37 cases) adopted the same nutrition product but enriched with arginine (9.0 g/L). The primary study objective was overall survival (OS). Secondary endpoints were progression-free survival (PFS); serum parameters including total protein, albumin, proalbumin, and transferrin obtained on preoperative day 1, postoperative day 2, and day 12; CD4(+) and CD8(+) T cells, natural killer (NK) cells, immunoglobulin M (IgM), and immunoglobulin G (IgG) obtained on preoperative day 1 and postoperative day 7. No significant differences in baseline characteristics were observed between groups. The group receiving arginine-enriched nutrition had a significantly better OS (P = 0.03, 41 vs. 30.5 months) and better PFS (P = 0.02, 18 vs. 11.5 months). On postoperative day 7, CD4(+) T cells, NK cells, IgM and IgG levels of the arginine-supplemented group increased prominently and were significantly higher than those of the control group and those on preoperative day 1. There is no significant difference in the serum total protein, albumin, proalbumin, and transferrin levels between the two arms. Arginine-supplemented enteral nutrition significantly improves long-term survival and restores immunity in malnourished gastric cancer.

Full Text Available PURPOSE: To compare the effect of parenteral versus enteral nutritional support in severe acute pancreatitis, with respect to efficacy, safety, morbidity, mortality and length of hospitalization. METHODS: The study was comprised of 31 patients, divided into a parenteral group (n=16 and an enteral group (n=15, who met severity criteria for abdominal tomography (Balthazar classes C, D, and E. The patients were compared by demographics, disease etiology, antibiotic prophylaxis, use or not of somatostatin, nutritional support, complications and disease progression. RESULTS: There was no statistical difference in the average duration of nutritional support, somatostatin, or antibiotics in the two groups. Imipenem was the drug of choice for prophylaxis of pancreatic infections in both groups. More complications occurred in the parenteral group, although the difference was not statistically significant (p=0.10. Infectious complications, such as catheter sepsis and infections of the pancreatic tissue, were significantly more frequent in the parenteral group (p=0.006. There was no difference in average length of hospitalization in the two groups. There were three deaths in the parenteral group and none in the enteral group. CONCLUSION: Enteral nutritional support is associated with fewer septic complications compared to parenteral nutritional support.OBJETIVO: Comparar o efeito do suporte nutricional parenteral versus enteral, em pancreatite aguda grave, com relação à eficácia, à segurança, à morbi-mortalidade e ao tempo de internação.

Full Text Available Los porcentajes de resistencia a penicilina entre los estreptococos del grupo viridans han llegado a niveles superiores al 60% en algunos estudios realizados en la década pasada, y en recientes trabajos se los encontró asociados a un mayor índice de mortalidad en las bacteriemias. Aún no se conoce cuál es el nivel de concentración inhibitoria mínima de penicilina para el cual resulta imposible lograr un efecto sinérgico con algún aminoglucósido. Con este propósito, se estudió la sensibilidad a penicilina de 28 cepas de estreptococos del grupo viridans aisladas de materiales clínicamente significativos en el Hospital de Pediatría "Prof. Dr. Juan P. Garrahan". Se seleccionaron siete aislamientos pertenecientes al grupo mitis con distintas características de sensibilidad, y con ellos se ensayó la curva de muerte frente a penicilina, gentamicina y penicilina más gentamicina, con concentraciones de penicilina por encima y por debajo de su concentración inhibitoria mínima. En ningún caso se observó sinergia cuando la concentración de penicilina fue inferior a la concentración inhibitoria mínima, al menos en este grupo particular de estreptococos que presentaron concentraciones inhibitorias mínimas de gentamicina ³ 16 µg/ml. Se encontró sinergia en cinco de las siete cepas cuando se trabajó con concentraciones de penicilina superiores a la concentración inhibitoria mínima. En las otras dos, se detectaron enzimas modificadoras de aminoglucósidos.Penicillin resistance rates higher than 60% have been recorded in viridans group streptococci by some authors during the 90's and recently such resistance was associated with higher levels of mortality in bacteremia.

Radiation enteritis with severe complications including intestinal bleeding, fistula, and stenosis were treated surgically in 9 cases. These 9 cases included 7 cases of cancer of the uterine cervix and 2 single cases of seminoma and melanoma. The patients received 60 Co or Linac x-ray external irradiation with or without intracavitary irradiation by a radium needle. Radiation injury began with melena, vaginorectal fistula, and intestinal obstruction 3 to 18 months after irradiation. One patient with melena underwent colostomy and survived 2 years. One of the three patients with vaginorectal fistula who had colostomy survived 1.5 years. In intestinal obstruction, one patients had bypass operation and three patients had resection of the intestine and the other had both. Leakage was noted in one patient, but the others had favorable prognosis. (Ueda, J.)

2016-02-01

An experiment was conducted to study potential interaction between the effects of feeding nitrate and docosahexaenoic acid (DHA; C22:6 n-3) on enteric CH4 production and performance of lactating dairy cows. Twenty-eight lactating Holstein dairy cows were grouped into 7 blocks of 4 cows. Within blocks, cows were randomly assigned to 1 of 4 treatments: control (CON; urea as alternative nonprotein N source to nitrate), NO3 [21 g of nitrate/kg of dry matter (DM)], DHA (3 g of DHA/kg of DM and urea as alternative nonprotein N source to nitrate), or NO3 + DHA (21 g of nitrate/kg of DM and 3 g of DHA/kg of DM, respectively). Cows were fed a total mixed ration consisting of 21% grass silage, 49% corn silage, and 30% concentrates on a DM basis. Feed additives were included in the concentrates. Cows assigned to a treatment including nitrate were gradually adapted to the treatment dose of nitrate over a period of 21 d during which no DHA was fed. The experimental period lasted 17 d, and CH4 production was measured during the last 5d in climate respiration chambers. Cows produced on average 363, 263, 369, and 298 g of CH4/d on CON, NO3, DHA, and NO3 + DHA treatments, respectively, and a tendency for a nitrate × DHA interaction effect was found where the CH4-mitigating effect of nitrate decreased when combined with DHA. This tendency was not obtained for CH4 production relative to dry matter intake (DMI) or to fat- and protein corrected milk (FPCM). The NO3 treatment decreased CH4 production irrespective of the unit in which it was expressed, whereas DHA did not affect CH4 production per kilogram of DMI, but resulted in a higher CH4 production per kilogram of fat- and protein-corrected milk (FPCM) production. The FPCM production (27.9, 24.7, 24.2, and 23. 8 kg/d for CON, NO3, DHA, and NO3 + DHA, respectively) was lower for DHA-fed cows because of decreased milk fat concentration. The proportion of saturated fatty acids in milk fat was decreased by DHA, and the proportion of

2017-01-01

Background Differentiating both typhoid (Salmonella Typhi) and paratyphoid (Salmonella Paratyphi A) infection from other causes of fever in endemic areas is a diagnostic challenge. Although commercial point-of-care rapid diagnostic tests (RDTs) for enteric fever are available as alternatives to the current reference standard test of blood or bone marrow culture, or to the widely used Widal Test, their diagnostic accuracy is unclear. If accurate, they could potentially replace blood culture as the World Health Organization (WHO)-recommended main diagnostic test for enteric fever. Objectives To assess the diagnostic accuracy of commercially available rapid diagnostic tests (RDTs) and prototypes for detecting Salmonella Typhi or Paratyphi A infection in symptomatic persons living in endemic areas. Search methods We searched the Cochrane Infectious Diseases Group Specialized Register, MEDLINE, Embase, Science Citation Index, IndMED, African Index Medicus, LILACS, ClinicalTrials.gov, and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) up to 4 March 2016. We manually searched WHO reports, and papers from international conferences on Salmonella infections. We also contacted test manufacturers to identify studies. Selection criteria We included diagnostic accuracy studies of enteric fever RDTs in patients with fever or with symptoms suggestive of enteric fever living in endemic areas. We classified the reference standard used as either Grade 1 (result from a blood culture and a bone marrow culture) or Grade 2 (result from blood culture and blood polymerase chain reaction, or from blood culture alone). Data collection and analysis Two review authors independently extracted the test result data. We used a modified QUADAS-2 extraction form to assess methodological quality. We performed a meta-analysis when there were sufficient studies for the test and heterogeneity was reasonable. Main results Thirty-seven studies met the inclusion

Enteral nutrition is the best way to feed or supplement the diet when gastrointestinal tract functions of patients are partially or totally preserved. Whenever total enteral nutrition is needed, it represents the only source of nutrients for patients. Thus, it is mandatory to ensure that high biological value proteins are included in enteral formulae. To assess the biological quality of a protein blend constituted by 50% potassium caseinate, 25% whey protein and 25% pea protein intended to be used in enteral nutrition products. Forty Wistar rats (20 male and 20 female), with initial body weight of 51 g, where divided into four groups and feed for 10 days with: casein (Control), experimental protein blend (Experimental), liophylized normo- and hyperproteic enteral nutrition formulae adapted to the animal nutritional requirements (Normoproteic and Hyperproteic). Protein efficiency ratio (PER), apparent digestibility coefficient (ADC), relationship between retained and absorbed nitrogen (R/A) and relationship between retained and consumed nitrogen (R/I) where calculated. Experimental and control groups had similar values for all analysed indices (PER, ADC, R/A and R/I). These indices where also similar between normo and hyperproteic groups, but lower than experimental and control groups, except in PER, where normoproteic group was either similar to control and hiperproteic group. The quality of the protein blend used in this study is high. It is a good protein source to be used in the development of new enteral nutritional products.

Iodine is essential for thyroid hormone synthesis, and iodine deficiency may result in thyroid disorders including goiter and hypothyroidism. Patients on long-term enteral nutrition (EN) or parenteral nutrition (PN) may be at risk for micronutrient deficiencies. The recommended daily allowance for iodine intake is 150 μg for nonpregnant adults. However, there is no current consensus among scientific societies regarding the quantity of iodine to be added in adult EN and PN formulations. The objective of this study was to determine the iodine content of U.S. adult enteral and parenteral nutrition solutions. This study also aimed to determine whether adult patients in the United States who are receiving long-term artificial nutrition may be at risk for iodine deficiency. Ten enteral nutrition solutions and 4 parenteral nutrition solutions were evaluated. The iodine contents of these solutions were measured spectrophotometrically and compared to the labeled contents. Measured and labeled EN iodine contents were similar (range 131-176 μg/L and 106-160 μg/L, respectively). In contrast, PN formulas were found to contain small, unlabeled amounts of iodine, averaging 27 μg/L. Typical fluid requirements are 30 to 40 mL/kg/day for adults receiving either total EN (TEN) or total PN (TPN). Adults on long-term TEN likely consume enough servings to meet their daily iodine requirements. However, patients on long-term TPN would require on average 5.6 L PN/day to meet the recommended daily allowance of iodine. This volume of PN is far in excess of typical consumption. Thus, U.S. patients requiring long-term TPN may be at risk for iodine deficiency. EN = enteral nutrition; PN = parenteral nutrition; TEN = total enteral nutrition; TPN = total parenteral nutrition; UIC = urinary iodine concentration.

Impaired gut motility may contribute, at least in part, to the development of systemic hyperammonemia and systemic neurological disorders in inherited metabolic disorders, or in severe liver and renal disease. It is not known whether enteric neurotransmission regulates intestinal luminal and hence systemic ammonia levels by induced changes in motility. Here, we propose and test the hypothesis that ammonia acts through specific enteric circuits to influence gut motility. We tested our hypothesis by recording the effects of ammonia on neuromuscular transmission in tissue samples from mice, pigs, and humans and investigated specific mechanisms using novel mutant mice, selective drugs, cellular imaging, and enzyme-linked immunosorbent assays. Exogenous ammonia increased neurogenic contractions and decreased neurogenic relaxations in segments of mouse, pig, and human intestine. Enteric glial cells responded to ammonia with intracellular Ca 2+ responses. Inhibition of glutamine synthetase and the deletion of glial connexin-43 channels in hGFAP :: Cre ER T2+/- /connexin43 f/f mice potentiated the effects of ammonia on neuromuscular transmission. The effects of ammonia on neuromuscular transmission were blocked by GABA A receptor antagonists, and ammonia drove substantive GABA release as did the selective pharmacological activation of enteric glia in GFAP::hM3Dq transgenic mice. We propose a novel mechanism whereby local ammonia is operational through GABAergic glial signaling to influence enteric neuromuscular circuits that regulate intestinal motility. Therapeutic manipulation of these mechanisms may benefit a number of neurological, hepatic, and renal disorders manifesting hyperammonemia. NEW & NOTEWORTHY We propose that local circuits in the enteric nervous system sense and regulate intestinal ammonia. We show that ammonia modifies enteric neuromuscular transmission to increase motility in human, pig, and mouse intestine model systems. The mechanisms underlying the

El tamaño de estas y el estado hipercatabólico son determinantes de la dinámica del tratamiento y la supervivencia del niño con grandes quemaduras. Objetivo: buscar la posible relación entre el soporte nutrimental establecido en las primeras horas después de la reanimación, y algunos indicadores pronósticos en niños quemados. Métodos: se realizó un estudio retrospectivo, de carácter analítico, que incluyó a 252 niños que tuvieron un ingreso en el servicio de quemados del Hospital Pediátrico Docente "Juan Manuel Márquez"de Marianao, en La Habana, con estadía superior a los 7 días, durante el decenio 2000-2009. A partir de la auditoría de las historias clínicas se obtuvieron los indicadores siguientes del pronóstico del niño quemado: superficie corporal quemada, tiempo de estadía, por ciento de pérdida de peso y mortalidad. De la misma forma se obtuvo la información acerca del tipo de soporte nutrimental metabólico empleado durante el tratamiento. Resultados: el tipo de soporte nutrimental metabólico más empleado fue el mixto, en el que se combinan las modalidades enteral y parenteral periférica, que abarcó al 52 % de los pacientes tratados. Los niños con menor por ciento de pérdida de peso (inferior al 10 % recibieron la forma enteral exclusiva (53,1 % de los casos tratados; en el 37,4 % el soporte fue mixto, pero usando la modalidad periférica de uso parenteral. Conclusiones: la estrategia nutrimental empleada en el niño quemado puede modificar algunos indicadores del pronóstico y debe ser una prioridad terapéutica para prevenir el deterioro clínico de estos pacientes.

Realizamos un estudio observacional, descriptivo, prospectivo, en un grupo de 268 pacientes con diagnóstico de ptosis mamaria con hipotrofia y mala calidad de cobertura por piel estriada, escaso tejido celular subcutáneo y pérdida del parénquima mamario, secundarios a lactancia prolongada y pérdida masiva de peso, entre otros, a las que se les practicó mamoplastia de aumento con implantes de silicona mediante la aplicación del método triplanar descrito por la autora, entre enero del 2004 y enero del 2013 en el Hospital de Bocagrande de Cartagena, Colombia. El diseño de la técnica se basa en los principios de cicatriz vertical descrita por Lassus o Lejour o mediante cicatriz en "J", descrita por la autora. El método triplanar se basa en tres planos de cobertura del implante. Plano I: submuscular, para cubrir los dos tercios superiores del implante. Plano II: colgajo dermoglandular con dos prolongaciones distales triangulares de tejido adiposo, en forma de pez, para cubrir el tercio inferior del implante y el borde libre del m

The radiological features of chronic radiation enteritis

The radiological findings, using a single-contrast barium infusion technique, are described in a series of 13 patients with chronic radiation enteritis. The signs include evidence of submucosal thickening, single or multiple stenoses, adhesions and sinus or fistula formation. A combination of these signs characterises the condition. This technique is particularly suited to the investigation of radiation enteritis because of its ability to distend maximally the small intestine. A cause, stenosis and/or adhesions, was demonstrated in the eight of the 13 patients presenting with intermittent small-intestinal obstruction. Three patients had diarrhoea as their predominant complaint and a fistula was demonstrated in two. (author)

Large amounts of animal health care data are present in veterinary electronic medical records (EMR) and they present an opportunity for companion animal disease surveillance. Veterinary patient records are largely in free-text without clinical coding or fixed vocabulary. Text-mining, a computer and information technology application, is needed to identify cases of interest and to add structure to the otherwise unstructured data. In this study EMR's were extracted from veterinary management programs of 12 participating veterinary practices and stored in a data warehouse. Using commercially available text-mining software (WordStat™), we developed a categorization dictionary that could be used to automatically classify and extract enteric syndrome cases from the warehoused electronic medical records. The diagnostic accuracy of the text-miner for retrieving cases of enteric syndrome was measured against human reviewers who independently categorized a random sample of 2500 cases as enteric syndrome positive or negative. Compared to the reviewers, the text-miner retrieved cases with enteric signs with a sensitivity of 87.6% (95%CI, 80.4-92.9%) and a specificity of 99.3% (95%CI, 98.9-99.6%). Automatic and accurate detection of enteric syndrome cases provides an opportunity for community surveillance of enteric pathogens in companion animals. Copyright © 2014 Elsevier B.V.

Full Text Available The enteric heath of growing poultry is imperative to success of the production. The basic role of poultry production is turning feed stuffs into meat. Any changes in this turning process, due to mechanical, chemical or biological disturbance of digestive system (enteric disorders is mostly accompanied with high economic losses due to poor performance, increased mortality rates and increased medication costs. The severity of clinical signs and course of the disorders are influenced several factors such as management, nutrition and the involved agent(s. Several pathogens (viruses, bacteria and parasites are incriminated as possible cause of enteric disorders either alone (mono-causal, in synergy with other micro-organisms (multi-causal, or with non-infectious causes such as feed and /or management related factors. In addition, excessive levels of mycotoxins and biogenic amines in feed lead to enteric disorders. Also factors such as high stocking density, poor litter conditions, poor hygiene and high ammonia level and other stressful situation may reduce the resistance of the birds and increases their susceptibility to infections. Under field conditions, however, under filed conditions it is difficult to determine whether the true cause of enteric disorders, is of infectious or non-infectious origin. In recent years and since the ban of use of antimicrobial growth promoters in several countries the incidence of intestinal disorders especially those caused by clostridial infection was drastically increased. The present review described in general the several factors involved in enteric disorders and summarized the available literatures about Clostridium perfringens infection in poultry.

Methane emissions from enteric fermentation of pigs are object of emission reporting. Hitherto they were treated as part of the energy balance of pigs, in accordance with IPCC guidance documents. They were calculated from the gross energy intake rate and a constant methane conversion ratio....... Meanwhile numerous experimental data on methane emissions from enteric fermentation is available in Germany and abroad; the results are compiled in this work. These results also allow for a description of transformation processes in the hind gut and a subsequent establishment of models that relate emissions...... to feed and performance data. The model by Kirchgeßner et al. (1995) is based on German experimental data and reflects typical national diet compositions. It is used to quantify typical emissions and methane conversion ratios. The results agree with other experimental findings at home and abroad...

Vaccines against enteric infections for the developing world

Science.gov (United States)

Czerkinsky, Cecil; Holmgren, Jan

2015-01-01

Since the first licensure of the Sabin oral polio vaccine more than 50 years ago, only eight enteric vaccines have been licensed for four disease indications, and all are given orally. While mucosal vaccines offer programmatically attractive tools for facilitating vaccine deployment, their development remains hampered by several factors: —limited knowledge regarding the properties of the gut immune system during early life;—lack of mucosal adjuvants, limiting mucosal vaccine development to live-attenuated or killed whole virus and bacterial vaccines;—lack of correlates/surrogates of mucosal immune protection; and—limited knowledge of the factors contributing to oral vaccine underperformance in children from developing countries.There are now reasons to believe that the development of safe and effective mucosal adjuvants and of programmatically sound intervention strategies could enhance the efficacy of current and next-generation enteric vaccines, especially in lesser developed countries which are often co-endemic for enteric infections and malnutrition. These vaccines must be safe and affordable for the world's poorest, confer long-term protection and herd immunity, and must be able to contain epidemics. PMID:25964464

Enteral versus parenteral nutrition and enteral versus a combination of enteral and parenteral nutrition for adults in the intensive care unit.

Critically ill people are at increased risk of malnutrition. Acute and chronic illness, trauma and inflammation induce stress-related catabolism, and drug-induced adverse effects may reduce appetite or increase nausea and vomiting. In addition, patient management in the intensive care unit (ICU) may also interrupt feeding routines. Methods to deliver nutritional requirements include provision of enteral nutrition (EN), or parenteral nutrition (PN), or a combination of both (EN and PN). However, each method is problematic. This review aimed to determine the route of delivery that optimizes uptake of nutrition. To compare the effects of enteral versus parenteral methods of nutrition, and the effects of enteral versus a combination of enteral and parenteral methods of nutrition, among critically ill adults, in terms of mortality, number of ICU-free days up to day 28, and adverse events. We searched CENTRAL, MEDLINE, and Embase on 3 October 2017. We searched clinical trials registries and grey literature, and handsearched reference lists of included studies and related reviews. We included randomized controlled studies (RCTs) and quasi-randomized studies comparing EN given to adults in the ICU versus PN or versus EN and PN. We included participants that were trauma, emergency, and postsurgical patients in the ICU. Two review authors independently assessed studies for inclusion, extracted data, and assessed risk of bias. We assessed the certainty of evidence with GRADE. We included 25 studies with 8816 participants; 23 studies were RCTs and two were quasi-randomized studies. All included participants were critically ill in the ICU with a wide range of diagnoses; mechanical ventilation status between study participants varied. We identified 11 studies awaiting classification for which we were unable to assess eligibility, and two ongoing studies.Seventeen studies compared EN versus PN, six compared EN versus EN and PN, two were multi-arm studies comparing EN versus PN

To review the benefits of enteral nutrition in contrast to the inflammatory consequences of administration of parenteral nutrition and enteral deprivation. To present the most recent evidence for the mechanisms of these immunologic changes and discuss potential areas for modification to decrease infectious complications of its administration. There is significant data supporting the early initiation of enteral nutrition in both medical and surgical patients unable to meet their caloric goals via oral intake alone. Despite the preference for enteral nutrition, some patients are unable to utilize their gut for nutritious gain and therefore require parenteral nutrition administration, along with its infectious complications. The mechanisms behind these complications are multifactorial and have yet to be fully elucidated. Recent study utilizing both animal and human models has provided further information regarding parenteral nutrition's deleterious effect on intestinal epithelial barrier function along with the complications associated with enterocyte deprivation. Changes associated with parenteral nutrition administration and enteral deprivation are complex with multiple potential areas for modification to allow for safer administration. Recent discovery of the mechanisms behind these changes present exciting areas for future study as to make parenteral nutrition administration in the enterally deprived patient safer.

Genomic diversification of giant enteric symbionts reflects host dietary lifestyles

KAUST Repository

Ngugi, David

2017-08-24

Herbivorous surgeonfishes are an ecologically successful group of reef fish that rely on marine algae as their principal food source. Here, we elucidated the significance of giant enteric symbionts colonizing these fishes regarding their roles in the digestive processes of hosts feeding predominantly on polysiphonous red algae and brown Turbinaria algae, which contain different polysaccharide constituents. Using metagenomics, single-cell genomics, and metatranscriptomic analyses, we provide evidence of metabolic diversification of enteric microbiota involved in the degradation of algal biomass in these fishes. The enteric microbiota is also phylogenetically and functionally simple relative to the complex lignocellulose-degrading microbiota of terrestrial herbivores. Over 90% of the enzymes for deconstructing algal polysaccharides emanate from members of a single bacterial lineage,

Principles of feeding cancer patients via enteral or parenteral nutrition during radiotherapy

International Nuclear Information System (INIS)

Fietkau, R.

1998-01-01

Background: The nutritional status of cancer patients is frequently impaired already before any therapy starts and may deteriorate even more by radio(chemo)therapy. Methods: This review describes the possibilities and risks of enteral and parenteral nutrition during radiotherapy. The indications of enteral nutrition will be derived from own results. Results: Enteral nutrition is the most preferable way of artificial long-term nutrition. In a prospective non-randomized trial we demonstrated that enteral nutrition via percutaneous endoscopic gastrostomy (PEG) not only improves the anthropometric and biochemical parameters during radio(chemo)therapy but also the quality of life of patients with advanced cancers of the head and neck. Moreover supportive use of megestrolacetate can improve the nutritional status. Parenteral nutrition is only recommended if enteral nutrition is not possible e.g. during radio(chemo)therapy of tumors of the upper gastrointestinal tract. Conclusions: Today adequate nutritional support is feasible during intensive radio(chemo)therapy. (orig.) [de

The genomes of canine parvovirus and mink enteritis virus were compared by restriction enzyme analysis of their replicative-form DNAs. Of 79 mapped sites, 68, or 86%, were found to be common for both types of DNA, indicating that canine parvovirus and mink enteritis virus are closely related viruses. Whether they evolved from a common precursor or whether canine parvovirus is derived from mink enteritis virus, however, cannot be deduced from our present data.

2017-09-01

Diarrhea often occurs during enteral nutrition. Recently, several reports showed that diarrhea improves by adding egg yolk lecithin, an emulsifier, in an enteral formula. Therefore, we evaluated if this combination could improve diarrhea outcomes. We retrospectively investigated the inhibitory effects on watery stools by replacing a polymeric fomula with that containing egg yolk lecithin. Then, we investigated the emulsion stability in vitro. Next, we examined the lipid absorption using different emulsifiers among bile duct-ligated rats and assessed whether egg yolk lecithin, medium-chain triglyceride, and dietary fiber can improve diarrhea outcomes in a rat model of short bowel syndrome. Stool consistency or frequency improved on the day after using the aforementioned combination in 13/14 patients. Average particle size of the egg yolk lecithin emulsifier did not change by adding artificial gastric juice, whereas that of soy lecithin and synthetic emulsifiers increased. Serum triglyceride concentrations were significantly higher in the egg yolk lecithin group compared with the soybean lecithin and synthetic emulsifier groups in bile duct-ligated rats. In rats with short bowels, the fecal consistency was a significant looser the dietary fiber (+) group than the egg yolk lecithin (+) groups from day 6 of test meal feedings. The fecal consistency was also a significant looser the egg yolk lecithin (-) group than the egg yolk lecithin (+) groups from day 4 of test meal feeding. The fecal consistency was no significant difference between the medium-chain triglycerides (-) and egg yolk lecithin (+) groups. Enteral formula emulsified with egg yolk lecithin promotes lipid absorption by preventing the destruction of emulsified substances by gastric acid. This enteral formula improved diarrhea and should reduce the burden on patients and healthcare workers.

Vaccines against enteric infections for the developing world.

Czerkinsky, Cecil; Holmgren, Jan

2015-06-19

Since the first licensure of the Sabin oral polio vaccine more than 50 years ago, only eight enteric vaccines have been licensed for four disease indications, and all are given orally. While mucosal vaccines offer programmatically attractive tools for facilitating vaccine deployment, their development remains hampered by several factors: -limited knowledge regarding the properties of the gut immune system during early life; -lack of mucosal adjuvants, limiting mucosal vaccine development to live-attenuated or killed whole virus and bacterial vaccines; -lack of correlates/surrogates of mucosal immune protection; and -limited knowledge of the factors contributing to oral vaccine underperformance in children from developing countries. There are now reasons to believe that the development of safe and effective mucosal adjuvants and of programmatically sound intervention strategies could enhance the efficacy of current and next-generation enteric vaccines, especially in lesser developed countries which are often co-endemic for enteric infections and malnutrition. These vaccines must be safe and affordable for the world's poorest, confer long-term protection and herd immunity, and must be able to contain epidemics. © 2015 The Author(s) Published by the Royal Society.

Galland, R.B.; Spencer, J.

1985-01-01

70 patients presenting to a surgical unit with radiation enteritis were followed up. 11 of the 61 who underwent operations died of operation-related causes. The 51 patients who survived for more than 3 months were followed up for up to 12 years (median 12 months). 24 had no further symptoms related to their radiation enteritis. The other 27 patients had persistence of symptoms, post-operative complications, new radiation-related problems, or a combination of these. The twenty new radiation-related problems were stricture (8 patients), malabsorption (5), fistula(1), and miscellaneous(6). These developed in in 12 of 36 patients presenting initially with stricture, compared with 8 of 9 patients presenting with a perforation or fistula (p=0.007 Fisher's exact test) and none whose first symptom was bleeding (p=0.001 vs perforation and fistula combined). 10 of the 27 patients with further problems required operations and 5 of them died. Radiation enteritis is thus a progressive disease, with further complications becoming apparent in about half of those surviving the initial lesion. Perforation or fistula formation indicates a poorer prognosis than does stricture or haemorrhage. (author)

2016-01-01

Full Text Available Oral drug delivery systems provide the most convenient, noninvasive, readily acceptable alternatives to parenteral systems. In the current work, eggshell-derived calcium carbonate (CaCO3 nanoparticles were used to develop enteric drug delivery system in the form of tablets. CaCO3 nanoparticles were manufactured using top-down ball-milling method and characterized by X-ray diffractometry (XRD and transmission electron microscopy (TEM and loaded with 5-fluorouracil as a model drug. Tablets with varying CaCO3 core and binder compositions were fabricated and coated with Eudragit S100 or Eudragit L100. Suitability for enteric delivery of the tablets was tested by oral administration to rabbits and radiography. Radiograph images showed that the tablet remained in the stomach of the rabbit for up to 3 hours. Further modifications of these biomaterial-derived nanoparticles and the coatings will enable manufacturing of stable formulations for slow or controlled release of pharmaceuticals for enteric delivery.

Management of Hyperglycemia During Enteral and Parenteral Nutrition Therapy

Science.gov (United States)

Umpierrez, Guillermo E.

2013-01-01

Hyperglycemia is a frequent complication of enteral and parenteral nutrition in hospitalized patients. Extensive evidence from observational studies indicates that the development of hyperglycemia during parenteral and enteral nutrition is associated with an increased risk of death and infectious complications. There are no specific guidelines recommending glycemic targets and effective strategies for the management of hyperglycemia during specialized nutritional support. Managing hyperglycemia in these patients should include optimization of carbohydrate content and administration of intravenous or subcutaneous insulin therapy. The administration of continuous insulin infusion and insulin addition to nutrition bag are efficient approaches to control hyperglycemia during parenteral nutrition. Subcutaneous administration of long-acting insulin with scheduled or corrective doses of short-acting insulin is superior to the sliding scale insulin strategy in patients receiving enteral feedings. Randomized controlled studies are needed to evaluate safe and effective therapeutic strategies for the management of hyperglycemia in patients receiving nutritional support. PMID:23065369

2012-01-01

Objective: To investigate the influence of early enteral nutrition therapy on the intestinal barrier function and immune response of the patients with radiation enteritis (ER) so as to find a relatively simple and effective method to treat RE. Methods: Fifty-six patients with radiation enteritis (RE) diagnosed by colonoscopy, X-rays, and pathology were randomly divided into 2 equal groups: experimental group undergoing enteral nutrition therapy, and control group undergoing conventional therapy only. Peripheral blood samples were collected 1, 11, and 21 days after admission. Plasma diamine oxidase (DAO), D-lactic acid, endotoxin, and lactulose/mannitol (L/M) ratio, and levels of IgG, IgM, and IgA, and CD4/CD8 ratio were examined. Five cases from the experimental group and 5 cases from the control group underwent second-time operation because of incomplete intestinal obstruction, intestinal stenosis, or recurrent tumor respectively. The biopsy specimens of the terminal ileum or distal descending colon taken during the first and second operations underwent pathological examination. Peripheral blood samples were collected 1, 11, and 21 days after admission. Plasma diamine oxidase (DAO), D-lactic acid, endotoxin, and lactulose/mannitol (L/M) ratio, and levels of IgG, IgM, and IgA, and CD4/CD8 ratio were examined. Results: There were no significant differences in the intestinal function and blood immunological indices between these 2 groups. The levels of DAO, D-lactic acid, and endotoxin,and the L/M ratio 11 days after admission of the experiment group were all significantly lower than those of the control group (t=2.568, 2.427, 2.143, 2.443, P<0.05), and all those indices 21 days after admission of the experiment group were all much more significantly lower in comparison with the control group (t=6.019, 12.834, 7.837, 7.997, P<0.01). The levels of IgG, IgM, and IgA, and CD4/CD8 ratio 11 days after admission of the experimental group were all significantly higher than

2017-05-26

Differentiating both typhoid (Salmonella Typhi) and paratyphoid (Salmonella Paratyphi A) infection from other causes of fever in endemic areas is a diagnostic challenge. Although commercial point-of-care rapid diagnostic tests (RDTs) for enteric fever are available as alternatives to the current reference standard test of blood or bone marrow culture, or to the widely used Widal Test, their diagnostic accuracy is unclear. If accurate, they could potentially replace blood culture as the World Health Organization (WHO)-recommended main diagnostic test for enteric fever. To assess the diagnostic accuracy of commercially available rapid diagnostic tests (RDTs) and prototypes for detecting Salmonella Typhi or Paratyphi A infection in symptomatic persons living in endemic areas. We searched the Cochrane Infectious Diseases Group Specialized Register, MEDLINE, Embase, Science Citation Index, IndMED, African Index Medicus, LILACS, ClinicalTrials.gov, and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) up to 4 March 2016. We manually searched WHO reports, and papers from international conferences on Salmonella infections. We also contacted test manufacturers to identify studies. We included diagnostic accuracy studies of enteric fever RDTs in patients with fever or with symptoms suggestive of enteric fever living in endemic areas. We classified the reference standard used as either Grade 1 (result from a blood culture and a bone marrow culture) or Grade 2 (result from blood culture and blood polymerase chain reaction, or from blood culture alone). Two review authors independently extracted the test result data. We used a modified QUADAS-2 extraction form to assess methodological quality. We performed a meta-analysis when there were sufficient studies for the test and heterogeneity was reasonable. Thirty-seven studies met the inclusion criteria and included a total of 5080 participants (range 50 to 1732). Enteric fever prevalence

Establishing enteral feeding is an important goal in the care of very low birth weight infants. In such infants, receipt of >/=50 mL/kg per day human milk during hospitalization has been associated with shorter time to full enteral feeding. The objective of this study was to determine whether high proportions (>/=50%) of human milk during feeding advancement are associated with shorter time to full enteral feeding and improved feeding tolerance. This was a prospective cohort study of very low birth weight infants (n = 127) who were grouped into low (/=50%; n = 93) human milk consumption groups according to their human milk proportion of enteral feeding during the time of feeding advancement. The primary outcomes of interest were ages at which 100 and 150 mL/kg per day enteral feedings were achieved. The high human milk group reached 100 mL/kg per day enteral feeding 4.5 days faster than the low human milk group. The high human milk group reached 150 mL/kg per day enteral feeding 5 days faster than the low human milk group. After adjustment for gestational age, gender, and respiratory distress syndrome, times to reach 100 and 150 mL/kg per day were significantly shorter for those in the high human milk group. Infants in the high human milk group had a greater number of stools per day; other indicators of feeding tolerance were not statistically different. In infants who weighed milk was associated with fewer days to full enteral feedings.

Enteral and Parenteral Nutrition in the Perioperative Period: State of the Art

Abunnaja, Salim; Cuviello, Andrea; Sanchez, Juan A.

2013-01-01

Nutritional support of surgical and critically ill patients has undergone significant advances since 1936 when Studley demonstrated a direct relationship between pre-operative weight loss and operative mortality. The advent of total parenteral nutrition followed by the extraordinary progress in parenteral and enteral feedings, in addition to the increased knowledge of cellular biology and biochemistry, have allowed clinicians to treat malnutrition and improve surgical patient’s outcomes. We reviewed the literature for the current status of perioperative nutrition comparing parenteral nutrition with enteral nutrition. In a surgical patient with established malnutrition, nutritional support should begin at least 7–10 days prior to surgery. Those patients in whom eating is not anticipated beyond the first five days following surgery should receive the benefits of early enteral or parenteral feeding depending on whether the gut can be used. Compared to parenteral nutrition, enteral nutrition is associated with fewer complications, a decrease in the length of hospital stay, and a favorable cost-benefit analysis. In addition, many patients may benefit from newer enteral formulations such as Immunonutrition as well as disease-specific formulations. PMID:23429491

Enteral Nutrition in Dementia: A Systematic Review

Directory of Open Access Journals (Sweden)

Joanne Brooke

2015-04-01

Full Text Available The aim of this systematic review is to evaluate the role of enteral nutrition in dementia. The prevalence of dementia is predicted to rise worldwide partly due to an aging population. People with dementia may experience both cognitive and physical complications that impact on their nutritional intake. Malnutrition and weight loss in dementia correlates with cognitive decline and the progress of the disease. An intervention for long term eating difficulties is the provision of enteral nutrition through a Percutaneous Endoscopic Gastrostomy tube to improve both nutritional parameters and quality of life. Enteral nutrition in dementia has traditionally been discouraged, although further understanding of physical, nutritional and quality of life outcomes are required. The following electronic databases were searched: EBSCO Host, MEDLINE, PubMed, Cochrane Database of Systematic Reviews and Google Scholar for publications from 1st January 2008 and up to and including 1st January 2014. Inclusion criteria included the following outcomes: mortality, aspiration pneumonia, pressure sores, nutritional parameters and quality of life. Each study included separate analysis for patients with a diagnosis of dementia and/or neurological disease. Retrospective and prospective observational studies were included. No differences in mortality were found for patients with dementia, without dementia or other neurological disorders. Risk factors for poor survival included decreased or decreasing serum albumin levels, increasing age or over 80 years and male gender. Evidence regarding pneumonia was limited, although did not impact on mortality. No studies explored pressure sores or quality of life.

Sequential intrahepatic metabolic effects of enteric galactose alimentation in newborn rats.

Kliegman, R M; Morton, S

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)

To investigate the effects of early enteral nutrition (EEN) on intra-abdominal pressure (IAP) and disease severity in patients with severe acute pancreatitis (SAP). Enteral nutrition (EN) was started within 48 h after admission in the EEN group and from the 8th day in the delayed enteral nutrition (DEN) group. The IAP and intra-abdominal hypertension (IAH) incidence were recorded for 2 weeks. The caloric intake and feeding intolerance (FI) incidence were recorded daily after EN was started. The severity markers and clinical outcome variables were also recorded. Sixty patients were enrolled to this study. No difference about IAP was found. The IAH incidence of the EEN group was significantly lower than that of the DEN group from the 9th day (8/30 versus 18/30; P = 0.009) after admission. The FI incidence of the EEN group was higher than that of the DEN group during the initial 3 days of feeding (25/30 versus 12/30; P = 0.001; 22/30 versus 9/30; P = 0.001; 15/30 versus 4/30; P = 0.002). Patients with an IAP FI incidence than those with an IAP ≥15 mmHg on the 1st day (20/22 versus 17/38; P < 0.001), the 3rd day (11/13 versus 8/47; P < 0.001), and the 7th day (3/5 versus 3/55; P = 0.005) of feeding. The severity markers and clinical outcome variables of the EEN group were significantly improved. Early enteral nutrition did not increase IAP. In contrast, it might prevent the development of IAH. In addition, EEN might be not appropriate during the initial 3-4 days of SAP onset. Moreover, EN might be of benefit to patients with an IAP <15 mmHg. Early enteral nutrition could improve disease severity and clinical outcome, but did not decrease mortality of SAP.

2017-12-01

Purpose: The feasibility of preparing an eslicarbazepine acetate suspension using Aptiom tablets for administration via enteral feeding tubes was evaluated. Methods: Eslicarbazepine acetate suspension (40 mg/mL) was prepared using Aptiom tablets after optimizing the tablet crushing methods and the vehicle composition. A stability-indicating high-performance liquid chromatography (HPLC) method was developed to monitor the eslicarbazepine stability in the prepared suspension. Three enteric feeding tubes of various composition and dimensions were evaluated for the delivery of the suspensions. The suspension was evaluated for the physical and chemical stability for 48 hours. Results: The reproducibility and consistency of particle size reduction was found to be best with standard mortar/pestle. The viscosity analysis and physical stability studies showed that ORA-Plus:water (50:50 v/v) was optimal for suspending ability and flowability of suspension through the tubes. The developed HPLC method was found to be stability indicating and suitable for the assay of eslicarbazepine acetate in the prepared suspension. The eslicarbazepine concentrations in separately prepared suspensions were within acceptable range (±3%), indicating accuracy and reproducibility of the procedure. The eslicarbazepine concentrations in suspensions before and after delivery through the enteric feeding tubes were within acceptable range (±4%), indicating absence of any physical/chemical interactions of eslicarbazepine with the tubes and a successful delivery of eslicarbazepine dosage via enteric feeding tubes. The stability study results showed that eslicarbazepine concentration in the suspension remained unchanged when stored at room temperature for 48 hours. Conclusion: The study presents a convenient procedure for the preparation of a stable suspension of eslicarbazepine acetate (40 mg/mL) using Aptiom tablets, for administration via enteral feeding tubes.

Malnutrition is a common consequence of inflammatory bowel disease (IBD). Diet has an important role in the management of IBD, as it prevents and corrects malnutrition. It is well known that diet may be implicated in the aetiology of IBD and that it plays a central role in the pathogenesis of gastrointestinal-tract disease. Often oral nutrition alone is not sufficient in the management of IBD patients, especially in children or the elderly, and must be combined with oral supplementation or replaced with tube enteral nutrition. In this review, we describe several different approaches to enteral nutrition—total parenteral, oral supplementation and enteral tube feeding—in terms of results, patients compliance, risks and and benefits. We also focus on the home entaral nutrition strategy as the future goal for treating IBD while focusing on patient wellness. PMID:25816159

Full Text Available Abstract Background Contact with animals and their environment has long been recognized as an important source of enteric zoonoses. However, there are limited data available on the burden of illness associated with specific types of animals in Canada. This study describes the overall burden of enteric zoonoses in Ontario, Canada from 2010 to 2012. Methods Confirmed cases of seven enteric zoonotic diseases (campylobacteriosis, cryptosporidiosis, giardiasis, listeriosis, salmonellosis, verotoxin-producing E. coli (VTEC infection, and yersiniosis with episode dates from 2010 to 2012 were extracted from the integrated Public Health Information System (iPHIS. Reported exposures were categorized as animal contact, foodborne, waterborne and ‘other’, with animal contact grouped into nine sub-categories based on the type of animal or transmission setting. Overall incidence rates and proportions by animal exposure categories, age and sex-specific incidence rates and hospitalization and death proportions were calculated and sex proportions compared. Results Our study found that approximately 26% of the enteric pathogens assessed during the 2010 to 2012 period reported contact with animals and their environments as the mode of transmission. Of enteric disease cases reporting animal contact, farm exposures were reported for 51.3%, dog or cat exposures for 26.3%, and reptile or amphibian exposures for 8.9%. Conclusions Contact with animals was reported more frequently during the period 2010 to 2012 in comparison to the period 1997 to 2003 when 6% or less of enteric cases were associated with animal contact. Public health professionals, stakeholders associated with animals and their related industries (e.g., pet treats, mobile zoos, abattoirs, and the public should recognize that animal contact is an important source of enteric illnesses in order to take measures to reduce the burden of illness from animal sources.

Enteral and Parenteral Nutrition in the Perioperative Period: State of the Art

Full Text Available Nutritional support of surgical and critically ill patients has undergone significant advances since 1936 when Studley demonstrated a direct relationship between pre-operative weight loss and operative mortality. The advent of total parenteral nutrition followed by the extraordinary progress in parenteral and enteral feedings, in addition to the increased knowledge of cellular biology and biochemistry, have allowed clinicians to treat malnutrition and improve surgical patient’s outcomes. We reviewed the literature for the current status of perioperative nutrition comparing parenteral nutrition with enteral nutrition. In a surgical patient with established malnutrition, nutritional support should begin at least 7–10 days prior to surgery. Those patients in whom eating is not anticipated beyond the first five days following surgery should receive the benefits of early enteral or parenteral feeding depending on whether the gut can be used. Compared to parenteral nutrition, enteral nutrition is associated with fewer complications, a decrease in the length of hospital stay, and a favorable cost-benefit analysis. In addition, many patients may benefit from newer enteral formulations such as Immunonutrition as well as disease-specific formulations.

Full Text Available Introduction: The incidence of malnutrition in hospitalized patients is reported to be high. In particular, patients with esophageal cancer are prone to malnutrition, due to preoperative digestive system dysfunctions and short-term non-oral feeding postoperatively. Selection of an appropriate method for feeding in the postoperative period is important in these patients.   Materials and Methods: In this randomized clinical trial, 40 patients with esophageal cancer who had undergone esophagectomy between September 2008 and October 2009 were randomly assigned into either enteral feeding or parenteral feeding groups, with the same calorie intake in each group. The level of serum total protein, albumin, prealbumin, transferrin, C3, C4 and hs-C-reactive protein          (hs-CRP, as well as the rate of surgical complications, restoration of bowel movements and cost was assessed in each group.   Results: Our results showed that there was no significant difference between the groups in terms of serum albumin, prealbumin or transferrin. However, C3 and C4 levels were significantly higher in the enteral feeding group compared with the parenteral group, while hs-CRP level was significantly lower in the enteral feeding group. Bowel movements were restored sooner and costs of treatment were lower in the enteral group. Postoperative complications did not differ significantly between the groups. There was one death in the parenteral group 10 days after surgery due to myocardial infarction.   Conclusion:  The results of our study showed that enteral feeding can be used effectively in the first days after surgery, with few early complications and similar nutritional outcomes compared with the parenteral method. Enteral feeding was associated with reduced inflammation and was associated with an improvement in immunological responses, quicker return of bowel movements, and reduced costs in comparison with parenteral feeding.

Full Text Available In the present study, a capsule formulation composed of enteric coated granules of Lactobacillus acidophilus ATCC 4962 was developed using Eudragit L30D-55 as enteric polymer. Optimization of the capsule formulation was achieved with a maximum viable cell count after 2 h of incubation in acid medium and disintegration time of 1 h in buffer pH 6.8. The amount of Eudragit L30D-55 in the capsules correlated with gastric juice resistance. The best protective qualities against artificial gastric juice were observed when capsules were prepared from granules composed of L. acidophilus, corn starch, lactose monohydrate, polyvinylpyrrolidone and coated with 12.5 % (m/V of Eudragit L30D-55. Capsule formulation of L. acidophilus in edible broth medium suspension serves as a cheap alternative to the expensive freeze-drying procedure for preparing L. acidophilus. In addition, the enteric coating using Eudragit L30D-55 could protect probiotics from the acidic gastric environment and enhance the bioactivity of probiotics along with replacement of pathogenic microbes in human intestine

In a large cohort of children with intestinal failure (IF), we sought to determine the cumulative incidence of achieving enteral autonomy and identify patient and institutional characteristics associated with enteral autonomy. A multicenter, retrospective cohort analysis from the Pediatric Intestinal Failure Consortium was performed. IF was defined as severe congenital or acquired gastrointestinal diseases during infancy with dependence on parenteral nutrition (PN) >60 days. Enteral autonomy was defined as PN discontinuation >3 months. A total of 272 infants were followed for a median (IQR) of 33.5 (16.2-51.5) months. Enteral autonomy was achieved in 118 (43%); 36 (13%) remained PN dependent and 118 (43%) patients died or underwent transplantation. Multivariable analysis identified necrotizing enterocolitis (NEC; OR 2.42, 95% CI 1.33-4.47), care at an IF site without an associated intestinal transplantation program (OR 2.73, 95% CI 1.56-4.78), and an intact ileocecal valve (OR 2.80, 95% CI 1.63-4.83) as independent risk factors for enteral autonomy. A second model (n = 144) that included only patients with intraoperatively measured residual small bowel length found NEC (OR 3.44, 95% CI 1.36-8.71), care at a nonintestinal transplantation center (OR 6.56, 95% CI 2.53-16.98), and residual small bowel length (OR 1.04 cm, 95% CI 1.02-1.06 cm) to be independently associated with enteral autonomy. A substantial proportion of infants with IF can achieve enteral autonomy. Underlying NEC, preserved ileocecal valve, and longer bowel length are associated with achieving enteral autonomy. It is likely that variations in institutional practices and referral patterns also affect outcomes in children with IF. Copyright © 2015 Elsevier Inc. All rights reserved.

Evaluation of diagnostic accuracy of abdominal CT depending on the type of enteric contrast agent. Multislice CTs of 2,008 patients with different types of oral preparation (positive with barium, n = 576; neutral with water, n = 716; and no enteric contrast, n = 716) were retrospectively evaluated by two radiologists including delineation of intestinal segments and influence on diagnosis and diagnostic reliability exerted by the enteric contrast, using a three-point scale. Furthermore, diagnostic reliability of the delineation of selected enteric pathologies was noted. CT data were assigned into groups: oncology, inflammation, vascular, pathology, trauma and gastrointestinal pathology. Delineation of the bowel was clearly practicable across all segments irrespective of the type of enteric contrast, though a slight impairment was observed without enteric contrast. Although delineation of intestinal pathologies was mostly classified "clearly delimitable" more difficulties occurred without oral contrast (neutral/positive/no contrast, 0.8 %/3.8 %/6.5 %). Compared to examinations without enteric contrast, there was a significant improvement in diagnosis that was even increased regarding the reader's diagnostic reliability. Positive opacification impaired detection of mucosal enhancement or intestinal bleeding. Water can replace positive enteric contrast agents in abdominal CTs. However, selected clinical questions require individual enteric contrast preparations. Pathology detection is noticeably impaired without any enteric contrast.

Recent advances in regenerative medicine to treat enteric neuropathies: use of human cells.

Stamp, L A; Young, H M

2017-01-01

As current options for treating most enteric neuropathies are either non-effective or associated with significant ongoing problems, cell therapy is a potential attractive possibility to treat congenital and acquired neuropathies. Studies using animal models have shown that following transplantation of enteric neural progenitors into the bowel of recipients, the transplanted cells migrate, proliferate, and generate neurons that are electrically active and receive synaptic inputs. Recent studies have transplanted human enteric neural progenitors into the mouse colon and shown engraftment. In this article, we summarize the significance of these recent advances and discuss priorities for future research that might lead to the use of regenerative medicine to treat enteric neuropathies in the clinic. © 2016 John Wiley & Sons Ltd.

Application of a PCR method for the diagnosis of ulcerative enteritis: preliminary results

2010-01-01

Full Text Available Ulcerative enteritis or “quail disease” is an acute clostridial infection of young birds reported in many avian species, chicken and turkey included. Clostridium colinum is the causative agent of ulcerative enteritis and because of the difficulties bound to the isolation and identification of this bacterium by means of classic bacteriological techniques, its detection appears very hard and the prevalence of this disease could be underestimated. To investigate the diffusion of C. colinum in enteric disease of birds, a recently developed PCR protocol was applied to 42 cultural broths previously inoculated with organs and intestinal samples collected from diseased subjects. PCR-positive broths were cultivated to attempt the isolation of C. colinum. Samples collected from positive birds were subjected to histological examinations. 4 birds (3 broilers chickens and 1 pigeon resulted PCR-positive and, in one case, C. colinum was isolated. Gross and histological lesions of positive birds were compatible with those described in other ulcerative enteritis outbreaks. These preliminary results demonstrates that C. colinum is sporadically implicated in enteric diseases of broiler chickens (14.2%. In addition, the PCR assay proved to be an useful and reliable instrument to support the diagnosis of ulcerative enteritis and to facilitate the isolation of C. colinum.

Radiation enteritis can cause late complications including stenosis, perforation, fistulization, and bleeding, which sometimes necessitate surgical treatment, but a complication of ileocutaneous fistula is rarely reported. In this paper, an excellent result of an operation for ileocutaneous fistula due to radiation enteritis is described. A 68-year-old woman had undergone extended total histerectomy and radiation therapy on uterine cervical cancer. After the operation and the radiation therapy, frequent abdominal pain bothered her and then the intestinal fistula ensued resulted in the fistulization. The fistula was located between two stenotic lesions of the intestine caused by radiation enteritis. Resection of ileum including the two stenotic lesion and the fistula and end-to-end anastomosis relieved the symptoms and the treatment course has been satisfactory. The two stenotic lesions were resected because it was suggested that the two stenotic lesions directly led the fistulization. She is now followed asymptomatically. (author).

Enteral administration of immune-modulating nutrients (eg, glutamine, omega-3 fatty acids, selenium, and antioxidants) has been suggested to reduce infections and improve recovery from critical illness. However, controversy exists on the use of immune-modulating enteral nutrition, reflected by lack of consensus in guidelines. To determine whether high-protein enteral nutrition enriched with immune-modulating nutrients (IMHP) reduces the incidence of infections compared with standard high-protein enteral nutrition (HP) in mechanically ventilated critically ill patients. The MetaPlus study, a randomized, double-blind, multicenter trial, was conducted from February 2010 through April 2012 including a 6-month follow-up period in 14 intensive care units (ICUs) in the Netherlands, Germany, France, and Belgium. A total of 301 adult patients who were expected to be ventilated for more than 72 hours and to require enteral nutrition for more than 72 hours were randomized to the IMHP (n = 152) or HP (n = 149) group and included in an intention-to-treat analysis, performed for the total population as well as predefined medical, surgical, and trauma subpopulations. High-protein enteral nutrition enriched with immune-modulating nutrients vs standard high-protein enteral nutrition, initiated within 48 hours of ICU admission and continued during the ICU stay for a maximum of 28 days. The primary outcome measure was incidence of new infections according to the Centers for Disease Control and Prevention (CDC) definitions. Secondary end points included mortality, Sequential Organ Failure Assessment (SOFA) scores, mechanical ventilation duration, ICU and hospital lengths of stay, and subtypes of infections according CDC definitions. There were no statistically significant differences in incidence of new infections between the groups: 53% (95% CI, 44%-61%) in the IMHP group vs 52% (95% CI, 44%-61%) in the HP group (P = .96). No statistically significant differences were

Delineation of the bowel was clearly practicable across all segments irrespective of the type of enteric contrast, though a slight impairment was observed without enteric contrast. Although delineation of intestinal pathologies was mostly classified ''clearly delimitable'' more difficulties occurred without oral contrast (neutral/positive/no contrast, 0.8 %/3.8 %/6.5 %). Compared to examinations without enteric contrast, there was a significant improvement in diagnosis that was even increased regarding the reader's diagnostic reliability. Positive opacification impaired detection of mucosal enhancement or intestinal bleeding. Water can replace positive enteric contrast agents in abdominal CTs. However, selected clinical questions require individual enteric contrast preparations. Pathology detection is noticeably impaired without any enteric contrast. circle Neutral oral contrast ensures an equivalent delineation of the bowel. (orig.)

RadCon: A Radiological Consequences Model

International Nuclear Information System (INIS)

Crawford, J.; Domel, R.U.

2000-05-01

RadCon estimates the dose received by user selected groups in the population from an accidental release of radionuclides to the environment. The exposure pathways considered are external exposure from the cloud and ground and internal exposure from inhalation and ingestion of contaminated food. Atmospheric dispersion modelling is carried out externally to RadCon.Given a two dimensional time varying air and ground concentration of radioactive elements, RadCon allows the user to: view the air and ground concentration over the affected area, select optional parameters and calculate the dose to people,display the results to the user, and change the parameter values. RadCon offers two user interfaces: 1) the standard graphical user interface which is started using Java DoseApp at the command line, or by setting up a shortcut to this command (particularly when RadCon is installed on a PC) and 2) the text based interface used to generate information for the model inter-comparison exercise . This is initiated using Java BIOMASS at the command line, or an equivalent shortcut. The text based interface was developed for research purposes and is not generally available. Appendices A, B and C provide a summary of instructions on setting up RadCon. This will generally be carried out by the computer support personnel

Clinical and nutritional implications of radiation enteritis

The clinical and nutritional significance of radiation enteritis was assessed in eight patients with chronic diarrhea which followed curative doses of radiotherapy for pelvic malignancies. Steatorrhea, found in seven malnourished patients, was ascribed to ileal disease or previous surgery, or to bacterial contamination of the small intestine. Lactose intolerance, assessed by breath hydrogen excretion after oral lactose and by jejunal lactase levels, was found in six patients. In a subgroup of five patients, the administration of two different defined formula liquid diets by nasoduodenal infusion decreased fecal fluid and energy losses by about one-half. Compared to Vivonex-HN, the infusion of Criticare-HN was associated with greater likelihood of intestinal gas production but a three-fold greater utilization of protein. Intestinal malabsorption and malnutrition in radiation enteritis has diverse etiologies. Whereas nutritional support by liquid diet limits fecal fluid and energy losses, these diets differ significantly in clinical tolerance and biologic value.

Full Text Available Pattern recognition receptors (PRRs sensing commensal microorganisms in the intestine induce tightly controlled tonic signaling in the intestinal mucosa, which is required to maintain intestinal barrier integrity and immune homeostasis. At the same time, PRR signaling pathways rapidly trigger the innate immune defense against invasive pathogens in the intestine. Intestinal epithelial cells and mononuclear phagocytes in the intestine and the gut-associated lymphoid tissues are critically involved in sensing components of the microbiome and regulating immune responses in the intestine to sustain immune tolerance against harmless antigens and to prevent inflammation. These processes have been mostly investigated in the context of the bacterial components of the microbiome so far. The impact of viruses residing in the intestine and the virus sensors, which are activated by these enteric viruses, on intestinal homeostasis and inflammation is just beginning to be unraveled. In this review, we will summarize recent findings indicating an important role of the enteric virome for intestinal homeostasis as well as pathology when the immune system fails to control the enteric virome. We will provide an overview of the virus sensors and signaling pathways, operative in the intestine and the mononuclear phagocyte subsets, which can sense viruses and shape the intestinal immune response. We will discuss how these might interact with resident enteric viruses directly or in context with the bacterial microbiome to affect intestinal homeostasis.

Contracting Parties to the Convention on the Prevention of Marine Pollution by Dumping of Wastes and other Matter (LC 1972) have requested the IAEA to develop an inventory of radioactive material entering the marine environment from all sources. The rationale for developing and maintaining the inventory is related to its use as an information base with which the impact of radionuclides entering the marine environment from different sources can be assessed and compared. Five anthropogenic sources of radionuclides entering the marine environment can be identified. These sources are: radioactive waste disposal at sea; accidents and losses at sea involving radioactive material; discharge of low level liquid effluents from land-based nuclear facilities; the fallout from nuclear weapons testing; and accidental releases from land-based nuclear facilities. The first two of these sources are most closely related to the objective of the LC 1972 and its request to the IAEA. This paper deals with the Agency's work on developing a database on radioactive material entering the marine environment from these two sources. The database has the acronym RAMEM (RAdioactive Material Entering the Marine Environment). It includes two modules: inventory of radioactive waste disposal at sea and inventory of accidents and losses at sea involving radioactive material

Galanin enhances systemic glucose metabolism through enteric Nitric Oxide Synthase-expressed neurons

Full Text Available Objective: Decreasing duodenal contraction is now considered as a major focus for the treatment of type 2 diabetes. Therefore, identifying bioactive molecules able to target the enteric nervous system, which controls the motility of intestinal smooth muscle cells, represents a new therapeutic avenue. For this reason, we chose to study the impact of oral galanin on this system in diabetic mice. Methods: Enteric neurotransmission, duodenal contraction, glucose absorption, modification of gut–brain axis, and glucose metabolism (glucose tolerance, insulinemia, glucose entry in tissue, hepatic glucose metabolism were assessed. Results: We show that galanin, a neuropeptide expressed in the small intestine, decreases duodenal contraction by stimulating nitric oxide release from enteric neurons. This is associated with modification of hypothalamic nitric oxide release that favors glucose uptake in metabolic tissues such as skeletal muscle, liver, and adipose tissue. Oral chronic gavage with galanin in diabetic mice increases insulin sensitivity, which is associated with an improvement of several metabolic parameters such as glucose tolerance, fasting blood glucose, and insulin. Conclusion: Here, we demonstrate that oral galanin administration improves glucose homeostasis via the enteric nervous system and could be considered a therapeutic potential for the treatment of T2D.

Four coal-based media, viz. alum-pretreated or ferric hydroxide-impregnated Giridih bituminous coal and lignite (alum-GBC, Fe-GBC; alum-lignite and Fe-Lignite) were laboratory tested to assess their potential in removing/inactivating enteric viruses in water. Batch-sorption screening tests, employing a poliovirus-spiked canal water, indicated high poliovirus sorption by Fe-GBC and alum-GBC in a short contact time of 5 min. Based on the results of further batch-sorption tests, using silver incorporated media (alum/Ag-GBC, alum-GBC-Ag and Fe-GBC-Ag), as well as aesthetic water quality consideration and previous findings on removal of coliforms and turbidity, alum/Ag-GBC, alum-GBC and alum-GBC-AG were included in downflow column studies employing poliovirus-spiked canal water. All three media showed potential in removing/inactivating enteric viruses. In a separate column study employing a joint challenge of poliovirus and rotavirus, alum/Ag-GBC removed 59.3-86.5% of the viruses along with more than 99% reduction in indigenous heterotrophic bacteria. Alum/silver-pretreated bituminous coal medium appears promising for use in household water filters in rural areas of the developing world. However, improved medium preparation to further enhance its efficiency is needed; also, its efficacy in removing/inactivating indigenous enteric bacteria, viruses and protozoa has to be ensured and practicalities or economics of application need to be considered.

Background and purpose: Chronic radiation proctitis/enteritis is a relevant complication of pelvic irradiation, which is still mainly treated by supportive measures only. There is some evidence that the combined treatment with pentoxifylline and tocopherol might alter the pathogenesis of radiation-induced fibrosis. In a retrospective analysis the clinical benefit of the treatment with pentoxifylline/tocopherol on radiation-induced proctitis/enteritis was evaluated, compared to supportive care only. Patients and methods: Of 30 patients with radiation-induced proctitis/enteritis grade I-II according to the RTOG/EORTC toxicity criteria, 21 were treated with pentoxifylline and tocopherol. Depending on physician's decision nine patients received symptomatic treatment only. Results: With pentoxifylline/tocopherol treatment 15/21 patients (71%) experienced a relief of their symptoms. A reduction from grade I/II to grade 0 toxicity was observed in seven and from grade II to grade I toxicity in eight patients. No improvement was seen in six patients. The median time to improvement with pentoxifylline and tocopherol treatment was 28 weeks. In three of nine patients who were treated supportively only, deterioration of symptoms occurred. Three patients experienced no amelioration, and three patients with grade I toxicity experienced a spontaneous relief of their symptoms (33%). Conclusion: The combination treatment with pentoxifylline and tocopherol seems to have a benefit in patients with grade I-II radiation-induced proctitis/enteritis. The optimal schedule of treatment duration is not yet clear. From the observations made in this study it is assumed the treatment should be given for 6-12 months at least. A prospective phase II study should be undertaken to evaluate optimal treatment duration. (orig.)

Enteral nutrition therapy is common practice in pediatric clinical settings. Often patients will receive a pump-assisted bolus feeding over 30 minutes several times per day using the same enteral feeding set (EFS). This study aims to determine the safest and most efficacious way to handle the EFS between feedings. Three EFS handling techniques were compared through simulation for bacterial growth, nursing time, and supply costs: (1) rinsing the EFS with sterile water after each feeding, (2) refrigerating the EFS between feedings, and (3) using a ready-to-hang (RTH) product maintained at room temperature. Cultures were obtained at baseline, hour 12, and hour 21 of the 24-hour cycle. A time-in-motion analysis was conducted and reported in average number of seconds to complete each procedure. Supply costs were inventoried for 1 month comparing the actual usage to our estimated usage. Of 1080 cultures obtained, the overall bacterial growth rate was 8.7%. The rinse and refrigeration techniques displayed similar bacterial growth (11.4% vs 10.3%, P = .63). The RTH technique displayed the least bacterial growth of any method (4.4%, P = .002). The time analysis in minutes showed the rinse method was the most time-consuming (44.8 ± 2.7) vs refrigeration (35.8 ± 2.6) and RTH (31.08 ± 0.6) ( P refrigerating the EFS between uses is the next most efficacious method for handling the EFS between bolus feeds.

Do low-calorie drinks 'cheat' the enteral-brain axis?

Science.gov (United States)

Ferreira, Adaliene V M; Generoso, Simone Vasconcelos; Teixeira, Antônio Lúcio

2014-09-01

The consumption of low-calorie beverages has increased worldwide, mainly because of their combination of sweet taste without adding significant calories to the diet. However, some epidemiological studies have linked the higher consumption of low-calorie beverages with increased body weight gain. Although a matter of debate, this paradoxical association between low-calorie beverages and weight gain has been attributed to their effect on the enteral-brain axis. More specifically, artificial sweeteners present in low-calorie beverages could induce appetite increase, probably due to an ambiguous psychobiological signal (uncoupling sweet taste from calorie intake) that confounds the appetite's regulatory mechanisms, promoting overeating and, ultimately, leading to weight gain. However, many studies do not support this assumption, and the mechanisms underlying the interaction between low-calorie beverages and the enteral-brain axis remain to be defined. The understanding of the effects of low-calorie drinks on the enteral-brain axis still remains in its infancy and needs to be unveiled. The consumption of low-calorie beverages reduces the calories from that drink, but compensatory phenomena may increase energy intake, and if so must be recognized and avoided.

Benefits of postpyloric enteral access placement by a nutrition support dietitian.

Jimenez, L Lee; Ramage, James E

2004-10-01

Although enteral nutrition is considered the preferred strategy for nutrition support, it is often precluded by nasogastric feeding intolerance or the inability to place feeding access into the postpyloric position. In an effort to improve enteral nutrition (EN) outcomes at our institution, the nutrition support dietitian (NSD) began placing postpyloric feeding tubes (PPFT) in intensive care unit patients. Intensive care unit patients who received blind, bedside PPFT placements by the NSD (n = 18) were compared with a concurrent age- and diagnosis-matched control group that received standard nutritional care without NSD intervention (n = 18). Interruption of EN infusion, appropriateness of parenteral nutrition (PN) prescription (based on American Society of Parenteral and Enteral Nutrition guidelines), and incidence of ventilator-associated pneumonia (VAP), as defined by the American College of Chest Physicians practice guidelines, were determined in each group. The NSD was successful in positioning the PPFT at or distal to the third portion of the duodenum in 83% of attempts. The PPFT group demonstrated no interruption of enteral feeding compared with 56% in the control group (p VAP in the PPFT group (6% vs 28%, p = .07). Of the PN initiations in the control group, 88% were deemed to be potentially avoidable; 6 of 8 PNs were initiated because of gastric residuals. Enteral nutrition facilitated by NSD placement of postpyloric feeding access is associated with improved tube feeding tolerance and reduced PN use. Further studies are needed to evaluate a possible effect of postpyloric feeding on the incidence of VAP.

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.

Al-Gousous, Jozef; Langguth, Peter

2016-02-01

To investigate the effect of calcium ions on the disintegration of enteric-coated dosage forms, disintegration testing was performed on enteric-coated aspirin tablets in the presence and absence of calcium in the test media. The results show that the presence of calcium ions retards the disintegration of enteric-coated dosage forms. This finding, which has not been reported in scientific literature, sheds light on the importance of conducting well-designed detailed investigations into the potential of calcium from dietary sources, calcium supplements, antacids, and/or phosphate binders affecting the absorption of drugs formulated into enteric-coated dosage forms. Moreover, it shows the necessity to investigate the potential of the occurrence of additional nutrient-excipient interactions. Copyright © 2016 American Pharmacists Association®.

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

Background  Enteral tubes are frequently inserted as part of medical treatment in a wide range of patient situations. Patients with an enteral tube are cared for by nurses in a variety of settings, including general and specialised acute care areas, aged care facilities and at home. Regardless of the setting, nurses have the primary responsibility for administering medication through enteral tubes. Medication administration via an enteral tube is a reasonably common nursing intervention that entails a number of skills, including preparing the medication, verifying the tube position, flushing the tube and assessing for potential complications. If medications are not given effectively through an enteral tube, harmful consequences may result leading to increased morbidity, for example, tube occlusion, diarrhoea and aspiration pneumonia. There are resultant costs for the health-care system related to possible increased length of stay and increased use of equipment. Presently what is considered to be best practice to give medications through enteral tubes is unknown. Objectives  The objective of this systematic review was to determine the best available evidence on which nursing interventions are effective in minimising the complications associated with the administration of medications via enteral tubes in adults. Nursing interventions and considerations related to medication administration included form of medication, verifying tube placement before administration, methods used to give medication, methods used to flush tubes, maintenance of tube patency and specific practices to prevent possible complications related to the administration of enteral medications. Search strategy  The following databases were searched for literature reported in English only: CINAHL, MEDLINE, The Cochrane Library, Current Contents/All Editions, EMBASE, Australasian Medical Index and PsychINFO. There was no date restriction applied. In addition, the reference lists of all included

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.

Bacteriophages as indicators of faecal pollution and enteric virus removal.

Science.gov (United States)

McMinn, B R; Ashbolt, N J; Korajkic, A

2017-07-01

Bacteriophages are an attractive alternative to faecal indicator bacteria (FIB), particularly as surrogates of enteric virus fate and transport, due to their closer morphological and biological properties. Based on a review of published data, we summarize densities of coliphages (F+ and somatic), Bacteroides spp. and enterococci bacteriophages (phages) in individual human waste, raw wastewater, ambient fresh and marine waters and removal through wastewater treatment processes utilizing traditional treatments. We also provide comparisons with FIB and enteric viruses whenever possible. Lastly, we examine fate and transport characteristics in the aquatic environment and provide an overview of the environmental factors affecting their survival. In summary, concentrations of bacteriophages in various sources were consistently lower than FIB, but more reflective of infectious enteric virus levels. Overall, our investigation indicates that bacteriophages may be adequate viral surrogates, especially in built systems, such as wastewater treatment plants. Bacteriophage are alternative fecal indicators that may be better surrogates for viral pathogens than fecal indicator bacteria (FIB). This report offers a summary of the existing literature concerning the utility of bacteriophage as indicators of viral presence (fecal sources and surface waters) and persistence (in built infrastructure and aquatic environments). Our findings indicate that bacteriophage levels in all matrices examined are consistently lower than FIB, but similar to viral pathogens. Furthermore, in built infrastructure (e.g. wastewater treatment systems) bacteriophage closely mimic viral pathogen persistence suggesting they may be adequate sentinels of enteric virus removal. © 2017 The Society for Applied Microbiology.

New perspective for nutritional support of cancer patients: Enteral/parenteral nutrition.

Science.gov (United States)

Akbulut, Gamze

2011-07-01

Cancer and its treatment result in severe biochemical and physiological alterations associated with a deterioration of quality of life (QoL). Cancer-related malnutrition may evolve into cancer cachexia due to complex interactions between pro-inflammatory cytokines and the host metabolism. Depending on the type of cancer treatment (either curative or palliative), the clinical condition of the patient and nutritional status, adequate and patient-tailored nutritional intervention should be prescribed (diet counseling, oral supplementation, enteral or total parenteral nutrition). Nutritional support has been widely advocated as adjunctive therapy for a variety of underlying illnesses, including surgery and medical oncotherapy (radiation or chemotherapy for cancer). Glutamine, n-3 fatty acids and probiotics/prebiotics are therapeutic factors that potentially modulate gastrointestinal toxicity related to cancer treatments. Enteral and parenteral nutrition may help improve patient survival, functional status and QoL, yet the benefits appear to be primarily limited to patients with good functional status and with gastrointestinal disease affecting nutritional intake. Parenteral nutrition offers the possibility of increased or maintenance of the nutrient intake in patients for whom normal food intake is inadequate and for whom enteral nutrition is not feasible, is contraindicated or is not accepted by the patient. This article reviews evidence on issues relevant to enteral and parenteral nutrition in patients with cancer.

Concanavalin-A (Con-A) hepatitis is regarded as a T cell-mediated model of acute liver injury. Mincle is a C-type lectin receptor (CLR) that is critical in the immune response to mycobacteria and fungi, but does not have a well-defined role in pre-clinical models of non-pathogen mediated inflammation. Since Mincle can ligate the cell death ligand SAP130, we postulated that Mincle signaling drives intrahepatic inflammation and liver injury in Con-A hepatitis. Acute liver injury was assessed in the murine Con-A hepatitis model using C57BL/6, Mincle−/−, and Dectin-1−/− mice. The role of C/EBPβ and HIF-1α signaling was assessed using selective inhibitors. We found that Mincle was highly expressed in hepatic innate inflammatory cells and endothelial cells in both mice and humans. Furthermore, sterile Mincle ligands and Mincle signaling intermediates were increased in the murine liver in Con-A hepatitis. Most significantly, Mincle deletion or blockade protected against Con-A hepatitis whereas Mincle ligation exacerbated disease. Bone marrow chimeric and adoptive transfer experiments suggested that Mincle signaling in infiltrating myeloid cells dictates disease phenotype. Conversely, signaling via other CLRs did not alter disease course. Mechanistically, we found that Mincle blockade decreased the NF-κβ related signaling intermediates, C/EBPβ and HIF-1α, both of which are necessary in macrophage-mediated inflammatory responses. Accordingly, Mincle deletion lowered production of nitrites in Con-A hepatitis and inhibition of both C/EBPβ and HIF1-α reduced the severity of liver disease. Our work implicates a novel innate immune driver of Con-A hepatitis and, more broadly, suggests a potential role for Mincle in diseases governed by sterile inflammation. PMID:27559045

Ventilator-associated pneumonia (VAP) is a common cause of morbidity in critically ill patients. Appropriate enteral feeding is the most important factor associated with the prevention of VAP. However, the standardization of enteral feeding methods needs clarification. The purpose of this systematic review was to synthesize the factors associated with enteral feeding in order to prevent VAP and to describe the characteristics of these factors. A comprehensive search was undertaken involving all major databases from their inception to September 2008 using medical subject heading terms associated with enteral feeding in relation to VAP. The overall reference list of identified studies was audited, and eligible studies included randomized controlled trials, controlled before-and-after (pre-post) studies and meta-analyses. To generate the characteristics of the factors associated with VAP, the reported components of these trials were pinpointed and categorized. A total of 14 papers were found that had investigated the factors linking enteral feeding and VAP. For these, 11 were randomized controlled trials, 1 was a meta-analysis and 2 were case-controlled analyses. Twelve of these 14 studies were conducted at a single institute and 2 were conducted at multiple institutes. The sample sizes varied from 10 to 2,528 subjects. Three major issues were identified based on the purpose of study interventions, and these were the effects of feeding method (continuous vs. intermittent), feeding site on aspiration (gastric vs. small bowel), and the timing of enteral feeding (early vs. late). The evidence suggests that a correct choice of enteral feeding method can effectively reduce complications due to aspiration. Furthermore, intermittent enteral feeding and with a small residual volume feed can reduce gastroesophageal reflux, and increased total intake volume and early feeding can reduce ICU mortality. Nonetheless, the effects of these choices on preventing VAP still need further

Casi la generalidad de los estudios realizados sobre cementos con adición de cenizas volantes se refieren a sus características y comportamiento en pastas, morteros y hormigones, siempre en relación con aquéllos del cemento portland. Esta vez, se desarrolló un trabajo experimental orientado a relacionar entre sí los cementos con adiciones de cenizas volantes y de puzolana natural. Para ello se fabricaron a escala de laboratorio cementos de ambos tipos, empleando como materias primas comunes clinker y yeso y, como variables, diferentes porcentajes de las dos adiciones, que cumplieron previamente los requisitos normalizados en cuanto a sus actividades puzolánicas. La calidad de los cementos fabricados resultó adecuada y concordante con la del cemento portland-puzolánico obtenido a escala industrial con los mismos clinker, yeso y puzolana natural de este estudio. Posteriormente, se determinaron las características de los cementos experimentales y se confeccionaron morteros normales para la realización de ensayos físicos y mecánicos. Los resultados de ensayos indicaron que los cementos con adición de cenizas volantes (CCV requieren menos agua para consistencia normal, presentan tiempos de fraguado mayores y expansiones en autoclave menores que los cementos con adición de puzolana (CP. Los calores de hidratación a 7 y 28 días de edad fueron aproximadamente similares para ambos tipos de cemento. En morteros normales, los cementos CCV mostraron menor retracción de secado, mayor retentividad y mayor fluidez (para igual cantidad de agua que los cementos CP. En los ensayos de exudación se observó que ésta depende más de la finura que el tipo de adición. Finalmente, los ensayos mecánicos señalaron que las resistencias a compresión y flexotracción de los morteros con cementos CCV son menores a edades inferiores que 14 días (del orden de 5 a 10% a un día de edad, pero que a partir de entonces pasan a ser mayores que las de

The present study evaluated the pathogens persistence and settling profile in swine effluent. We determined the enteric pathogens settling characteristics, their survival and inactivation profile in swine effluent (for water reuse purpose) and in sludge (generated after aerobic treatment - during secondary settling process). The study was performed in laboratorial-scale and in full-scale (manure treatment plant). Enteric viruses and enteric bacteria were used as biomarkers. Results showed that these enteric pathogens were significantly reduced from swine effluent during secondary settling process, and enteric viruses removal was correlated with the suspended solids decantation. The design of secondary settlers can be adapted to improve pathogens removal, by diminishing the solids loading rate per area and time, ending in higher hydraulic retention times.

2013-05-01

Full Text Available Entrepreneurs typically have limited resources during the start-up phase of a business. Business ecosystems are a strategy for entrepreneurs to access and exchange many different aspects of value, resources, and benefits. However, there may be business risks for entering a particular type of ecosystem, and further risks may be encountered after entering and participating in a business ecosystem. These risks are significant and can inhibit a startup's growth. In this article, the literature on business ecosystems is reviewed as it relates to risk to discover insights of relevance to entrepreneurs, top management teams, and business-ecosystem operators. First, the published research is organized into two streams: i risks relating to categories of business ecosystems, and ii risks relating to participating in business ecosystems. Then, the problem is abstracted to develop a potential strategy for managing these risks, which features a pre-entry inspection followed by real-time resource management. Finally, five recommendations are offered for entrepreneurs seeking to enter and participate in business ecosystems.

The aim of this study was to determine how employee well-being, psychosocial factors at work, leadership and perceived occupational health services predict entering rehabilitation as modelled in the Job Well-being Pyramid. A random population of 967 civil servants participated in a survey on psychosocial factors and health at work in 2000 in Finland. A total of 147 employees entered rehabilitation during the median follow-up time of 7 years. Permanent employment, large organizations, feedback from supervisors, client violence and physically monotonous work were associated with an increased rate of entering rehabilitation, whereas physical jobs, clear aims, high appreciation, job satisfaction and job enjoyment were associated with a decreased rate of entering rehabilitation. Employee well-being in general was also associated with entering rehabilitation, and this was decreased by good work ability, good health, mental well-being and physical fitness and increased by constant musculoskeletal symptoms. On the other hand, support from supervisors, job control, work pressure, team climate at work, communication, bullying and discrimination, physical work environment, and sense of coherence appeared to have no association. Various psychosocial factors at work and job well-being predict entering rehabilitation. The association between employee health and entering rehabilitation refers to the fact that the selection process for rehabilitation works reasonably well and those in need of rehabilitation are also granted it. In general, these findings coincide well with the Job Well-being Pyramid model. Improving job conditions and well-being at work is likely to decrease the need for rehabilitation.

Oral microbial flora and a damaged oral mucosa may increase the risk of bacteriemia, fungemia and complications in immunocompromised patients. Assessment of presence: bacteria and Candida spp. in different oral lesions, and the incidence of bacteremia in the case of a damaged mucosa in transplant recipients and patients receiving anti-tumour chemotherapy. Forty-five patients – 18 months to 18 years of life, were included (20 – organ recipients, 14– anti-tumour chemotherapy, 11 – control group). Clinical, oral mucosa examination focused on the type, severity and site of lesions, and microbiology assessed the presence of bacteria and fungi in the material from lesions. Blood cultures were performed in ten immunocompromised patients with manifestations of systemic infection. The control material consisted of blood cultures made prior to the onset of oral lesions and after 4–6 weeks following their remission in a diagnosed bacteremia. The statistical analysis was performed. In the subjects with secondary immunodeficiency, among other coagulase-negative Staphylococcus (CoNS), Candidia spp. were more frequent. In cancer patients, mucositis was associated with Candida spp., Streptococcus spp. Organ recipients with stomatitis exhibited the presence of CoNS, Streptococcus viridians and other. Oral lesions in the control group contained Haemophilus parainfluenzae, Neisseria spp. and Staphylococcus aureus. In 30% of immunocompromised patients, oral lesions were accompanied by bacteremia. A correlation has been found between oral lesions and the presence of S. aureus in patients without secondary immunodeficiency, and of CoNS, Enterococcus spp., Candida spp. in immunocompromised patients.

A significant number of patients treated for head and neck squamous cell cancer (HNSCC) undergo enteral tube feeding. Data suggest that avoiding enteral feeding can prevent long-term tube dependence and disuse of the swallowing mechanism which has been linked to complications such as prolonged dysphagia and esophageal constriction. We examined detailed dosimetric and clinical parameters to better identify those at risk of requiring enteral feeding. One hundred patients with advanced stage HNSCC were retrospectively analyzed after intensity-modulated radiation therapy (IMRT) to a median dose of 70 Gy (range: 60-75 Gy) with concurrent chemotherapy in nearly all cases (97%). Patients with significant weight loss (>10%) in the setting of severely reduced oral intake were referred for placement of a percutaneous endoscopic gastrostomy (PEG) tube. Detailed DVH parameters were collected for several structures. Univariate and multivariate analyses using logistic regression were used to determine clinical and dosimetric factors associated with needing enteral feeding. Dichotomous outcomes were tested using Fisher’s exact test and continuous variables between groups using the Wilcoxon rank-sum test. Thirty-three percent of patients required placement of an enteral feeding tube. The median time to tube placement was 25 days from start of treatment, after a median dose of 38 Gy. On univariate analysis, age (p = 0.0008), the DFH (Docetaxel/5-FU/Hydroxyurea) chemotherapy regimen (p = .042) and b.i.d treatment (P = 0.040) (used in limited cases on protocol) predicted need for enteral feeding. On multivariate analysis, age remained the single statistically significant factor (p = 0.003) regardless of other clinical features (e.g. BMI) and all radiation planning parameters. For patients 60 or older compared to younger adults, the odds ratio for needing enteral feeding was 4.188 (p = 0.0019). Older age was found to be the most significant risk factor for needing enteral feeding in

Full Text Available El objetivo general de este artículo es evaluar los efectos de la inseguridad ciudadana en el uso del espacio público. Dicha evaluación exige analizar dos relaciones que se establecen en el ámbito de la violencia: la relación entre victimización y percepción de inseguridad; y la que se establece entre actitudes sociales y resolución pacífica de conflictos nacionales. Para ello, se analizaron las variables victimización, percepción de inseguridad, uso del espacio físico, actitudes hacia el sistema institucional político y social y hacia la resolución de conflictos nacionales, y las posibles relaciones entre ellas. Los datos para realizar el estudio se obtuvieron por medio de una encuesta que se llevó a cabo con 1 200 personas de 18 y 70 años de edad residentes en la ciudad de Santiago. Los resultados indican que Santiago es una ciudad de habitantes con temor y que el aumento de la percepción de inseguridad de sus habitantes contrasta con el hecho de que las tasas de victimización se hayan mantenido, más o menos, constantes en los años que precedieron a la encuesta. El temor se relaciona con el abandono del espacio público físico y sociopolítico, así como con el refugio en los espacios y la vida privados. La actitud de resolver los conflictos por medios no pacíficos es frecuente y se asocia en mayor medida con la inseguridad, la actitud negativa hacia la democracia y la falta de expectativas sobre el futuro del país. Los resultados de este estudio respaldan la idea de que para superar el temor la gente tiende a adaptarse a la realidad adoptando una postura conformista, homogeneizando las creencias y los comportamientos, y sobreestimando la fuerza como medio para resolver las diferencias.

To review the available evidence that examines the association between climatic and agricultural land use factors and the risks of enteric zoonoses in humans and consider information needs and possible pathways of intervention. The electronic databases PubMed, Web of Science and Embase and government websites were searched systematically for published literature that investigated the association of climatic and/or agricultural exposures with the incidence of the four most common enteric zoonotic diseases in New Zealand (campylobacteriosis, salmonellosis, cryptosporidiosis and giardiasis). Results The 16 studies in the review demonstrated significant associations between climate, agricultural land use and enteric disease occurrence. The evidence suggests that enteric disease risk from environmental reservoirs is pathogen specific. In some rural regions, environmental pathogen load is considerable, with multiple opportunities for zoonotic transmission. Enteric disease occurrence in NZ is associated with climate variability and agricultural land use. However, these relationships interact with demographic factors to influence disease patterns. Improved understanding of how environmental and social factors interact can inform effective public health interventions under scenarios of projected environmental change. © 2014 Public Health Association of Australia.

Lupus enteritis: from clinical findings to therapeutic management

Science.gov (United States)

2013-01-01

Lupus enteritis is a rare and poorly understood cause of abdominal pain in patients with systemic lupus erythematosus (SLE). In this study, we report a series of 7 new patients with this rare condition who were referred to French tertiary care centers and perform a systematic literature review of SLE cases fulfilling the revised ACR criteria, with evidence for small bowel involvement, excluding those with infectious enteritis. We describe the characteristics of 143 previously published and 7 new cases. Clinical symptoms mostly included abdominal pain (97%), vomiting (42%), diarrhea (32%) and fever (20%). Laboratory features mostly reflected lupus activity: low complement levels (88%), anemia (52%), leukocytopenia or lymphocytopenia (40%) and thrombocytopenia (21%). Median CRP level was 2.0 mg/dL (range 0–8.2 mg/dL). Proteinuria was present in 47% of cases. Imaging studies revealed bowel wall edema (95%), ascites (78%), the characteristic target sign (71%), mesenteric abnormalities (71%) and bowel dilatation (24%). Only 9 patients (6%) had histologically confirmed vasculitis. All patients received corticosteroids as a first-line therapy, with additional immunosuppressants administered either from the initial episode or only in case of relapse (recurrence rate: 25%). Seven percent developed intestinal necrosis or perforation, yielding a mortality rate of 2.7%. Altogether, lupus enteritis is a poorly known cause of abdominal pain in SLE patients, with distinct clinical and therapeutic features. The disease may evolve to intestinal necrosis and perforation if untreated. Adding with this an excellent steroid responsiveness, timely diagnosis becomes primordial for the adequate management of this rare entity. PMID:23642042

New perspective for nutritional support of cancer patients: Enteral/parenteral nutrition

Science.gov (United States)

AKBULUT, GAMZE

2011-01-01

Cancer and its treatment result in severe biochemical and physiological alterations associated with a deterioration of quality of life (QoL). Cancer-related malnutrition may evolve into cancer cachexia due to complex interactions between pro-inflammatory cytokines and the host metabolism. Depending on the type of cancer treatment (either curative or palliative), the clinical condition of the patient and nutritional status, adequate and patient-tailored nutritional intervention should be prescribed (diet counseling, oral supplementation, enteral or total parenteral nutrition). Nutritional support has been widely advocated as adjunctive therapy for a variety of underlying illnesses, including surgery and medical oncotherapy (radiation or chemotherapy for cancer). Glutamine, n-3 fatty acids and probiotics/prebiotics are therapeutic factors that potentially modulate gastrointestinal toxicity related to cancer treatments. Enteral and parenteral nutrition may help improve patient survival, functional status and QoL, yet the benefits appear to be primarily limited to patients with good functional status and with gastrointestinal disease affecting nutritional intake. Parenteral nutrition offers the possibility of increased or maintenance of the nutrient intake in patients for whom normal food intake is inadequate and for whom enteral nutrition is not feasible, is contraindicated or is not accepted by the patient. This article reviews evidence on issues relevant to enteral and parenteral nutrition in patients with cancer. PMID:22977559

The primary cilium is a non-motile cilium whose structure is 9+0. It is involved in co-ordinating cellular signal transduction pathways, developmental processes and tissue homeostasis. Defects in the structure or function of the primary cilium underlie numerous human diseases, collectively termed ciliopathies. The presence of single cilia in the central nervous system (CNS) is well documented, including some choroid plexus cells, neural stem cells, neurons and astrocytes, but the presence of primary cilia in differentiated neurons of the enteric nervous system (ENS) has not yet been described in mammals to the best of our knowledge. The enteric nervous system closely resembles the central nervous system. In fact, the ultrastructure of the ENS is more similar to the CNS ultrastructure than to the rest of the peripheral nervous system. This research work describes for the first time the ultrastructural characteristics of the single cilium in neurons of rat duodenum myenteric plexus, and reviews the cilium function in the CNS to propose the possible role of cilia in the ENS cells. © 2012 The Authors.

Full Text Available Background: Adequate nutritional support is important for the comprehensive management of patients in intensive care units (ICUs. Aim: The study was aimed to survey prevalent enteral nutrition practices in the trauma intensive care unit, nurses′ perception, and their knowledge of enteral feeding. Study Design: The study was conducted in the ICU of a level 1 trauma center, Jai Prakash Narayan Apex Trauma Centre, AIIMS, New Delhi, India. The study design used an audit. Materials and Methods: Sixty questionnaires were distributed and the results analyzed. A database was prepared and the audit was done. Results: Forty-two (70% questionnaires were filled and returned. A majority (38 of staff nurses expressed awareness of nutrition guidelines. A large number (32 of staff nurses knew about nutrition protocols of the ICU. Almost all (40 opined enteral nutrition to be the preferred route of nutrition unless contraindicated. All staff nurses were of opinion that enteral nutrition is to be started at the earliest (within 24-48 h of the ICU stay. Everyone opined that the absence of bowel sounds is an absolute contraindication to initiate enteral feeding. Passage of flatus was considered mandatory before starting enteral nutrition by 86% of the respondents. Everyone knew that the method of Ryle′s tube feeding in their ICU is intermittent boluses. Only 4 staff nurses were unaware of any method to confirm Ryle′s tube position. The backrest elevation rate was 100%. Gastric residual volumes were always checked, but the amount of the gastric residual volume for the next feed to be withheld varied. The majority said that the unused Ryle′s tube feed is to be discarded after 6 h. The most preferred (48% method to upgrade their knowledge of enteral nutrition was from the ICU protocol manual. Conclusion: Information generated from this study can be helpful in identifying nutrition practices that are lacking and may be used to review and revise enteral feeding

Contamination of enteral diets represents a high risk of compromising the patient's medical condition. To assess the microbiological quality and aseptic conditions in the preparation and administration of handmade and industrialized enteral diets offered in a hospital in the Valley of Jequitinhonha, MG, Brazil, we performed a microbiological analysis of 50 samples of diets and 27 samples of surfaces, utensils, and water used in the preparation of the diets. In addition, we assessed the good handling practices of enteral diets according to the requirements specified by the Brazilian legislation. Both kinds of enteral diets showed contamination by coliforms and Pseudomonas spp. No sample was positive for Staphylococcus aureus and Salmonella spp. On the other hand, Listeria spp. was detected in only one sample of handmade diets. Contamination was significantly higher in the handmade preparations (p Nonconformities were detected with respect to good handling practices, which may compromise the diet safety. The results indicate that the sanitary quality of the enteral diets is unsatisfactory, especially handmade diets. Contamination by Pseudomonas spp. is significant because it is often involved in infection episodes. With regard to aseptic practices, it was observed the need of implementing new procedures for handling enteral diets.

The role of enteric glial cells has somewhat changed from that of mere mechanical support elements, gluing together the various components of the enteric nervous system, to that of active participants in the complex interrelationships of the gut motor and inflammatory events. Due to their multiple functions, spanning from supporting elements in the myenteric plexuses to neurotransmitters, to neuronal homeostasis, to antigen presenting cells, this cell population has probably more intriguing abilities than previously thought. Recently,some evidence has been accumulating that shows how these cells may be involved in the pathophysiological aspects of some diseases. This review will deal with the properties of the enteric glial cells more strictly related to gastrointestinal motor function and the human pathological conditions in which these cells may play a role, suggesting the possibility of enteric neurogliopathies.

Nutritional status of patients significantly affects the outcome of surgical treatment, whether it's about being obese or malnutrition with loss of muscle mass. Inadequate nutritional support in the perioperative period compromises surgical procedures even in patients who are adequately nourished. In this paper, particular attention was paid to malnourished patients, and their incidence in population hospitalized in surgical wards can be high up to 30%. Special emphasis was paid to the appropriateness of preoperative fasting and to the acceptance of new knowledge in this area of treatment. The aim of this working group was to make guidelines for perioperative nutritional support with different modalities of enteral nutrition. The development of these guidelines was attended by representatives of Croatian Medical Association: Croatian Society for Digestive Surgery, Croatian Society for Clinical Nutrition, Croatian Society of Surgery, Croatian Society for Endoscopic Surgery, Croatian Trauma Society and the Croatian Society of Anesthesiology and Intensive Care. The guidelines are designed as a set of questions that arise daily in clinical practice when preparing patients for surgery and after the surgical treatment, which relate to the assessment of nutritional status, perioperative nutritional support, duration of preoperative fasting period and the selection of food intake route. Assessment of nutritional status and the use of different modes of enteral nutrition should enter into standard protocols of diagnosis and treatment in the Croatian hospitals.

Enteral versus parenteral nutrition in cancer patients: evidences and controversies.

Science.gov (United States)

Cotogni, Paolo

2016-01-01

The debate over the use of enteral nutrition (EN) and parenteral nutrition (PN) is an old but evergreen and hot topic. Since many years, studies comparing EN and PN have been a pivotal 'leitmotif' in the published literature on artificial nutrition (AN). Actually, there is a background misunderstanding in this debate; specifically, that EN and PN are competitors in the choice of the route for delivering nutrition support in cancer patients. Conversely, EN and PN have specific indications and contraindications. This review has the purpose to discuss the indications and complications as well as pros and cons of EN and PN in cancer patients, the crucial role of nutrition support in oncology patients during anticancer treatments and throughout the course of disease, and, finally, the role of AN in advanced cancer patients. In summary, we have no evidence-based data able to definitively indicate the optimal method for delivering AN in cancer patients. EN and PN have to be considered equally effective in maintaining or improving nutritional status in cancer patients. Besides, this review strongly supports the recommendation that a baseline nutritional assessment should be carried out by a healthcare professional expert in AN for all cancer patients at the time of diagnosis or anticancer treatment plan, taking the nutritional status, estimated duration of AN, AN-related potential benefits and possible complications into consideration on an individual basis. Moreover, the patient symptoms, performance status, estimated life expectancy, and mainly, will or preferences have to be evaluated and incorporated into the nutrition support plan before the definitive choice of the route for delivering nutrients is decided. Finally, applying a decision-making process tailored to patient needs-regardless of whether receiving or not anticancer treatment-allows to choose reasonably the optimal nutritional support strategy.

Entering adulthood in a recession tempers later narcissism.

Science.gov (United States)

Bianchi, Emily C

2014-07-01

Despite widespread interest in narcissism, relatively little is known about the conditions that encourage or dampen it. Drawing on research showing that macroenvironmental conditions in emerging adulthood can leave a lasting imprint on attitudes and behaviors, I argue that people who enter adulthood during recessions are less likely to be narcissistic later in life than those who come of age in more prosperous times. Using large samples of American adults, Studies 1 and 2 showed that people who entered adulthood during worse economic times endorsed fewer narcissistic items as older adults. Study 3 extended these findings to a behavioral manifestation of narcissism: the relative pay of CEOs. CEOs who came of age in worse economic times paid themselves less relative to other top executives in their firms. These findings suggest that macroenvironmental experiences at a critical life stage can have lasting implications for how unique, special, and deserving people believe themselves to be. © The Author(s) 2014.

Enteral feeding via jejunostomy as a cause of intestinal perforation and necrosis

Directory of Open Access Journals (Sweden)

María Victoria Vieiro-Medina

Full Text Available Background: Jejunostomy for enteral feeding is excellent for patients who cannot manage oral intake, with a low complication rate. A Foley catheter, Ryle tube, Kerh tube or needle-catheter (Jejuno-Cath® are commonly used. It is a safe procedure but it can lead to severe complications. Case report: We present two cases: firstly, an 80 year old male who was admitted to the Emergency Room with a bowel perforation secondary to Jejuno-Cath® for enteral feeding after a subtotal gastrectomy with Roux-en-Y reconstruction; and secondly, a 53 year old male who was admitted to the Emergency Room due to gastric perforation developing multiple complications, including bowel necrosis and enteral feeding impaction. Discussion: We have reviewed the recent literature with regard to this rare complication.

Glucose, epithelium, and enteric nervous system: dialogue in the dark.

Science.gov (United States)

Pfannkuche, H; Gäbel, G

2009-06-01

The gastrointestinal epithelium is in close contact with the various components of the chymus, including nutrients, bacteria and toxins. The epithelial barrier has to decide which components are effectively absorbed and which components are extruded. In the small intestine, a nutrient like glucose is mainly absorbed by the sodium linked glucose cotransporter 1 (SGLT1) and the glucose transporter 2 (GLUT2). The expression and activity of both transport proteins is directly linked to the amount of intraluminal glucose. Besides the direct interaction between glucose and the enterocytes, glucose also stimulates different sensory mechanisms within the intestinal wall. The most important types of cells involved in the sensing of intraluminal contents are enteroendocrine cells and neurones of the enteric nervous system. Regarding glucosensing, a distinct type of enteroendocrine cells, the enterochromaffine (EC) cells are involved. Excitation of EC cells by intraluminal glucose results in the release of serotonin (5-HT), which modulates epithelial functions and activates enteric secretomotorneurones. Enteric neurones are not only activated by 5-HT, but also directly by glucose. The activation of different cell types and the subsequent crosstalk between these cells may trigger appropriate absorptive and secretory processes within the intestine.

A quantitative systematic identification and prioritization of unmet needs and research opportunities in relation to enteral nutrition was conducted by means of a tailor-made health research prioritization process. The research objectives were reached by conducting qualitative interviews followed by quantitative questionnaires targeting enteral nutrition key opinion leaders (KOLs). (1) Define disease areas that deserve more research attention; (2) Rank importance of product characteristics of tube feeding (TF) and oral nutritional supplements (ONS); (3) Assess involvement of KOLs in enteral nutrition R&D process. KOLs ranked three product characteristics and three disease areas that deserve additional research attention. From these, overall priority scores were calculated by multiplying ranks for both product characteristics and disease areas. 17 qualitative interviews were conducted and 77 questionnaires (response rate 35%) were completed and returned. (1) Disease areas in ONS and TF with highest priorities are: ONS: general malnutrition & geriatrics, TF: intensive care. (2) TF product characteristics with highest priorities are: composition and clinical evidence from a KOL perspective; tolerance and ease of use from a patient perspective. ONS product characteristics with highest priorities are: composition, clinical evidence and taste from a KOL perspective; taste from a patient perspective. We find a high discrepancy between product characteristic prioritization from a KOL and patient perspective. (3) Although 62% of all KOLs give advice to enteral nutrition companies on patient needs, they under-influence the setting of research priorities by enteral nutrition companies. This study provides a systematic approach to achieve research prioritization in enteral nutrition. In addition to providing new directions for enteral nutrition research and development, this study highlights the relevance of involving KOLs in the identification of research priorities as they

We calculate the heating power of the neutral beam injection (NBI) in the = 4.8% high-beta discharge achieved in the Large Helical Device (LHD). We investigate the difference of the heating efficiency and the heating power profile between with and without the re-entering fast ion effects. When the re-entering fast ion effects are taken into account, the heating efficiency in the co injection of the NBI (co-NBI case) is improved and it is about 1.8 times larger than that without the re-entering effects. In contrast, the heating efficiency with the re-entering effects in the counter injection of the NBI (ctr-NBI case) rarely differs from that without the re-entering ones. We also study the re-entering fast ion effects on the transport properties in the LHD high beta discharges. It is found that the tendency of the thermal conductivities on the beta value is not so much sensitive with and without the re-entering effects. In addition, we investigate the difference in the re-entering fast ion effects caused by the field strength and the magnetic configuration. In the co-NBI case, the re-entering fast ion effects on the heating efficiency increases with the decrease of the field strength. In the contrast, the re-entering fast ion effects in the ctr-NBI case rarely differs by changing the field strength. (author)

Background Low dose aspirin reduces the secondary incidence of myocardial infarction and stroke. Drug resistance to aspirin might result in treatment failure. Despite this concern, no clear definition of “aspirin resistance” has emerged and estimates of its incidence have varied remarkably. We aimed to determine the commonality of a mechanistically consistent, stable and specific phenotype of true pharmacological resistance to aspirin – such as might be explained by genetic causes. Methods and Results Healthy volunteers (n=400) were screened for their response to a single oral dose of 325 mg immediate release or enteric coated aspirin. Response parameters reflected the activity of aspirin's molecular target, cyclooxygenase-1. Individuals who appeared “aspirin resistant” on one occasion underwent repeat testing and if still “resistant” were exposed to low dose enteric coated aspirin (81 mg) and clopidogrel (75 mg) for one week each. Variable absorption caused a high frequency of apparent resistance to a single dose of 325 mg enteric coated aspirin (up to 49%) but not to immediate release aspirin (0%). All individuals responded to aspirin upon repeated exposure, extension of the post dosing interval or addition of aspirin to their platelets ex vivo. Conclusions Pharmacological resistance to aspirin is rare; this study failed to identify a single case of true drug resistance. Pseudoresistance, reflecting delayed and reduced drug absorption, complicates enteric coated but not immediate release aspirin administration.

Transmesocolic double gastro-enteric fistulas due to ingestion of 28 magnets

Directory of Open Access Journals (Sweden)

Adrian Surd

2018-05-01

Full Text Available Introduction: Accidental ingestion of magnetic foreign bodies has become more common due to increased availability of objects and toys with magnetic elements. The majority of them traverse the gastrointestinal system spontaneously without complication. However, ingestion of multiple magnets may require surgical resolution. Magnet ingestion usually does not cause serious complications, but in case of multiple magnet ingestion or ingestion of magnet and a metal object, it could cause intestinal obstruction, fistula formation or even perforation. Case report: We report case of a transmesocolic double gastro-enteric fistula formation following ingestion of 28 small magnets in a 17 months old boy. No history of foreign body ingestion could be obtained from parents therefore the patient was treated conservatively in a pediatric clinic for vomiting, dehydration, upper respiratory tract infection and suspicion of upper digestive tract bleeding. After 48 h he was sent in our clinic for surgical evaluation. Intraoperatively double transmesocolic gastro-enteric fistula was found. After separation of de gastric and enteral walls, resection of gastric wall and intestinal segment containing the two perforations was performed, followed by gastric suture in two layers and entero-enteric anastomosis. A total of 28 magnets were removed from the stomach and small intestine. Conclusion: Single magnet ingestion is treated as non-magnetic foreign body. Multiple magnet ingestion should be closely monitored and surgical approach could be the best option to prevent or to cure its complications. Keywords: Ingestion, Magnetic foreign body, Multiple magnets, Intestinal fistula, Children

Transgastrostomy jejunal intubation for enteric alimentation.

McLean, G K; Rombeau, J L; Caldwell, M D; Ring, E J; Freiman, D B

1982-12-01

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.

Full Text Available Contamination of enteral diets represents a high risk of compromising the patient's medical condition. To assess the microbiological quality and aseptic conditions in the preparation and administration of handmade and industrialized enteral diets offered in a hospital in the Valley of Jequitinhonha, MG, Brazil, we performed a microbiological analysis of 50 samples of diets and 27 samples of surfaces, utensils, and water used in the preparation of the diets. In addition, we assessed the good handling practices of enteral diets according to the requirements specified by the Brazilian legislation. Both kinds of enteral diets showed contamination by coliforms and Pseudomonas spp. No sample was positive for Staphylococcus aureus and Salmonella spp. On the other hand, Listeria spp. was detected in only one sample of handmade diets. Contamination was significantly higher in the handmade preparations (p < 0.05. Nonconformities were detected with respect to good handling practices, which may compromise the diet safety. The results indicate that the sanitary quality of the enteral diets is unsatisfactory, especially handmade diets. Contamination by Pseudomonas spp. is significant because it is often involved in infection episodes. With regard to aseptic practices, it was observed the need of implementing new procedures for handling enteral diets.

The objective of this work was to use hot-melt extrusion (HME) technology to improve the physiochemical properties of lansoprazole (LNS) to prepare stable enteric coated LNS tablets. For the extrusion process, we chose Kollidon ® 12 PF (K12) polymeric matrix. Lutrol ® F 68 was selected as the plasticizer and magnesium oxide (MgO) as the alkalizer. With or without the alkalizer, LNS at 10% drug load was extruded with K12 and F68. LNS changed to the amorphous phase and showed better release compared to that of the pure crystalline drug. Inclusion of MgO improved LNS extrudability and release and resulted in over 80% drug release in the buffer stage. Hot-melt extruded LNS was physically and chemically stable after 12 months of storage. Both formulations were studied for compatibility with Eudragit ® L100-55. The optimized formulation was compressed into a tablet followed by coating process utilizing a pan coater using L100-55 as an enteric coating polymer. In a two-step dissolution study, the release profile of the enteric coated LNS tablets in the acidic stage was less than 10% of the LNS, while that in the buffer stage was more than 80%. Drug content analysis revealed the LNS content to be 97%, indicating the chemical stability of the enteric coated tablet after storage for six months. HME, which has not been previously used for LNS, is a valuable technique to reduce processing time in the manufacture of enteric coated formulations of an acid-sensitive active pharmaceutical ingredient as compared to the existing methods.

mucosal barrier as a key step in enteric pathogen survival. We review key observations relevant to the roles of LT and cholera toxin in protective immunity and the effects of these toxins on innate mucosal defenses. We suggest either that toxin-mediated fluid secretion mechanically disrupts the mucus...... layer or that toxins interfere with innate mucosal defenses by other means. Such a breach gives pathogens access to the enterocyte, leading to binding and pathogenicity by enterotoxigenic E. coli (ETEC) and other organisms. Given the common exposure to LT(+) ETEC by humans visiting or residing...... unexpectedly broad protective effects against LT(+) ETEC and mixed infections when using a toxin-based enteric vaccine.

Physical activity could benefit drug users' physiological and mental health. Previous research has suggested that physical activity levels change when drug users enter prison. Twenty-five class A drug users who were new to prison answered physical activity and drug use cross-sectional questionnaires, took a submaximal fitness test and wore a pedometer for 1 week. Participants' mean aerobic capacity was estimated as 49 mls O2/kg/min (±12 SD). Their mean self-reported walking distance outside of prison was 4.67 miles on an average day (±4.14 SD). Pedometer data suggest they walked a mean of 1.8 miles/day in prison. Many class A drug users entering prison had high levels of fitness and physical activity before admission, often gained from walking. Walking activity reduced when they entered prison, posing a challenge to maintaining healthy activity levels.

Enteral peptide formulas inhibit radiation induced enteritis and apoptosis in intestinal epithelial cells and suppress the expression and function of Alzheimer's and cell division control gene products

Studies have shown that patients receiving enteral peptide formulas prior to irradiation have a significantly reduced incidence of enteritis and express a profound increase in intestinal cellularity. Two conceptual approaches were taken to describe this response. First was the evaluation in changes in programmed intestinal cell death and secondly the evaluation of a gene product controlling cell division cycling. This study provided a relationship between the ratio of cell death to cell formulations. The results indicate that in the canine and murine models, irradiation induces expression of the Alzheimer's gene in intestinal crypt cells, while the incidence of apoptosis in apical cells is significantly increased. The use of peptide enteral formulations suppresses the expression of the Alzheimer's gene in crypt cells, while apoptosis is eliminated in the apical cells of the intestine. Concomitantly, enteral peptide formulations suppress the function of the CK-II gene product in the basal and baso-lateral cells of the intestine. These data indicate that although the mitotic index is significantly reduced in enterocytes, this phenomenon alone is not sufficient to account for the peptide-induced radio-resistance of the intestine. The data also indicate a significant reduction of normal apoptosis in the upper lateral and apical cells of the intestinal villi. Thus, the ratio of cell death to cell replacement is significantly decreased resulting in an increase in villus height and hypertrophy of the apical villus cells. Thus, peptide solutions should be considered as an adjunct treatment both in radio- and chemotherapy

Full Text Available Introducción: la talla baja se ha descrito como característica clínica de niños con retinoblastoma. Esta particularidad puede estar relacionada directamente con la enfermedad de base o con factores externos.  Objetivo: el propósito de esta investigación fue conocer la frecuencia de talla y peso bajos en niños mexicanos con retinoblastoma y correlacionar los valores antropométricos con variables de la enfermedad y ambientales. Materiales y métodos: se analizaron expedientes clínicos de 346 pacientes con retinoblastoma. Se obtuvieron los datos de peso y talla referidos al ingreso; antes del tratamiento. Se comparó el valor de Z con las referencias de la distribución normal de la población mexicana. La asociación de las medidas antropométricas con las variables clínicas, sociales y genéticas se estableció con la prueba de c2. Resultados: la talla y el peso promedio de los niños con retinoblastoma fueron significativamente más bajos que los de la población general (p < 0.001 y p = 0.013, respectivamente. La talla y peso bajos fueron más frecuentes en niños con enfermedad avanzada, provenientes de medio rural y de bajo nivel socioeconómico. Conclusiones: los déficits en peso y talla en niños con retinoblastoma se deben a factores relacionados con enfermedad avanzada al momento del diagnóstico, lo cual a su vez es consecuencia de la situación de marginación de la población rural mexicana.

Full Text Available Abstract Background The objective of this study was to determine whether neonatal nasogastric enteral feeding tubes are colonised by the opportunistic pathogen Cronobacter spp. (Enterobacter sakazakii and other Enterobacteriaceae, and whether their presence was influenced by the feeding regime. Methods One hundred and twenty-nine tubes were collected from two neonatal intensive care units (NICU. A questionnaire on feeding regime was completed with each sample. Enterobacteriaceae present in the tubes were identified using conventional and molecular methods, and their antibiograms determined. Results The neonates were fed breast milk (16%, fortified breast milk (28%, ready to feed formula (20%, reconstituted powdered infant formula (PIF, 6%, or a mixture of these (21%. Eight percent of tubes were received from neonates who were 'nil by mouth'. Organisms were isolated from 76% of enteral feeding tubes as a biofilm (up to 107 cfu/tube from neonates fed fortified breast milk and reconstituted PIF and in the residual lumen liquid (up to 107 Enterobacteriaceae cfu/ml, average volume 250 μl. The most common isolates were Enterobacter cancerogenus (41%, Serratia marcescens (36%, E. hormaechei (33%, Escherichia coli (29%, Klebsiella pneumoniae (25%, Raoultella terrigena (10%, and S. liquefaciens (12%. Other organisms isolated included C. sakazakii (2%,Yersinia enterocolitica (1%,Citrobacter freundii (1%, E. vulneris (1%, Pseudomonas fluorescens (1%, and P. luteola (1%. The enteral feeding tubes were in place between 48 h (13%. All the S. marcescens isolates from the enteral feeding tubes were resistant to amoxicillin and co-amoxiclav. Of additional importance was that a quarter of E. hormaechei isolates were resistant to the 3rd generation cephalosporins ceftazidime and cefotaxime. During the period of the study, K. pneumoniae and S. marcescens caused infections in the two NICUs. Conclusion This study shows that neonatal enteral feeding tubes

Enteral Nutrition for Feeding Severely Underfed Patients with Anorexia Nervosa

2012-09-01

Full Text Available Severe undernutrition nearly always leads to marked changes in body spaces (e.g., alterations of intra-extracellular water and in body masses and composition (e.g., overall and compartmental stores of phosphate, potassium, and magnesium. In patients with severe undernutrition it is almost always necessary to use oral nutrition support and/or artificial nutrition, besides ordinary food; enteral nutrition should be a preferred route of feeding if there is a functional accessible gastrointestinal tract. Refeeding of severely malnourished patients represents two very complex and conflicting tasks: (1 to avoid “refeeding syndrome” caused by a too fast correction of malnutrition; (2 to avoid “underfeeding” caused by a too cautious rate of refeeding. The aim of this paper is to discuss the modality of refeeding severely underfed patients and to present our experience with the use of enteral tube feeding for gradual correction of very severe undernutrition whilst avoiding refeeding syndrome, in 10 patients aged 22 ± 11.4 years and with mean initial body mass index (BMI of 11.2 ± 0.7 kg/m2. The mean BMI increased from 11.2 ± 0.7 kg/m2 to 17.3 ± 1.6 kg/m2 and the mean body weight from 27.9 ± 3.3 to 43.0 ± 5.7 kg after 90 days of intensive in-patient treatment (p < 0.0001. Caloric intake levels were established after measuring resting energy expenditure by indirect calorimetry, and nutritional support was performed with enteral feeding. Vitamins, phosphate, and potassium supplements were administered during refeeding. All patients achieved a significant modification of BMI; none developed refeeding syndrome. In conclusion, our findings show that, even in cases of extreme undernutrition, enteral feeding may be a well-tolerated way of feeding.

Human adenovirus 41 (HAdV-41) causes acute gastroenteritis in young children. The main characteristics of HAdV-41 infection are diarrhea and vomiting. Nevertheless, the precise mechanism of HAdV-41-induced diarrhea is unknown, as a suitable small-animal model has not been described. In this study, we used the human midgut carcinoid cell line GOT1 to investigate the effect of HAdV-41 infection and the individual HAdV-41 capsid proteins on serotonin release by enterochromaffin cells and on enteric glia cell (EGC) activation. We first determined that HAdV-41 could infect the enterochromaffin cells. Immunofluorescence staining revealed that the cells expressed HAdV-41-specific coxsackievirus and adenovirus receptor (CAR); flow cytometry analysis supported these findings. HAdV-41 infection of the enterochromaffin cells induced serotonin secretion dose dependently. In contrast, control infection with HAdV-5 did not induce serotonin secretion in the cells. Confocal microscopy studies of enterochromaffin cells infected with HAdV-41 revealed decreased serotonin immunofluorescence compared to that in uninfected cells. Incubation of the enterochromaffin cells with purified HAdV-41 short fiber knob and hexon proteins increased the serotonin levels in the harvested cell supernatant significantly. HAdV-41 infection could also activate EGCs, as shown in the significantly altered expression of glia fibrillary acidic protein (GFAP) in EGCs incubated with HAdV-41. The EGCs were also activated by serotonin alone, as shown in the significantly increased GFAP staining intensity. Likewise, EGCs were activated by the cell supernatant of HAdV-41-infected enterochromaffin cells. IMPORTANCE The nonenveloped human adenovirus 41 causes diarrhea, vomiting, dehydration, and low-grade fever mainly in children under 2 years of age. Even though acute gastroenteritis is well described, how human adenovirus 41 causes diarrhea is unknown. In our study, we analyzed the effect of human adenovirus 41

Raw vegetables irrigated with groundwater that may contain enteric viruses can be associated with food-borne viral disease outbreaks. In this study, we performed reverse transcription-PCR (RT-PCR) and cell culture-PCR to monitor the occurrence of enteric viruses in groundwater samples and in raw vegetables that were cultivated using that groundwater in South Korea. Samples were collected 10 times from three farms located in Gyeonggi Province, South Korea. RT-PCR and cell culture-PCR were performed to detect adenoviruses (AdVs), enteroviruses (EVs), noroviruses (NoVs), and rotaviruses, followed by sequence analyses of the detected strains. Of the 29 groundwater samples and the 30 vegetable samples, five (17%) and three (10%) were positive for enteric viruses, respectively. AdVs were the most frequently detected viruses in four groundwater and three vegetable samples. EVs and NoVs were detected in only one groundwater sample and one spinach sample, respectively. The occurrence of enteric viruses in groundwater and vegetable samples was not correlated with the water temperature and the levels of indicator bacteria, respectively. Phylogenetic analysis indicated that most of the detected AdVs were temporally distributed, irrespective of sample type. Our results indicate that raw vegetables may be contaminated with a broad range of enteric viruses, which may originate from virus-infected farmers and virus-contaminated irrigation water, and these vegetables may act as a potential vector of food-borne viral transmission.

The consequences at the family level of having a child with enteric stoma have been a matter of deep concern in the nursing practice. This type of stoma is performed in children as an adjunctive procedure in the treatment of a congenital, pathological and traumatic problem but there is evidence to suggest that this functional change has an impact on different aspects of everyday family life.

Objective: To identify evidence in the literature on the impact of enteric stoma (ileostomy and colostomy for the child and for his family.

Method: A literature review of 14 research projects which address the experiences of the Family and the child with ostomy located in the Cinahl, Medline, Ovid, Proquest, Lilacs, and Dedalus databases.

Result: through the analysis it may be concluded that, although health professionals believe that stomata are a technology of low complexity, for child and family they do not have the same meaning, because they alter the lifestyle and the family’s dynamics.

Conclusions: test results indicated there is need for understanding the subject, in order to contribute in building knowledge, aimed at implementing interventions that consider the impact of stoma on the child and on his family.

Scheme for Entering Binary Data Into a Quantum Computer

Science.gov (United States)

Williams, Colin

2005-01-01

A quantum algorithm provides for the encoding of an exponentially large number of classical data bits by use of a smaller (polynomially large) number of quantum bits (qubits). The development of this algorithm was prompted by the need, heretofore not satisfied, for a means of entering real-world binary data into a quantum computer. The data format provided by this algorithm is suitable for subsequent ultrafast quantum processing of the entered data. Potential applications lie in disciplines (e.g., genomics) in which one needs to search for matches between parts of very long sequences of data. For example, the algorithm could be used to encode the N-bit-long human genome in only log2N qubits. The resulting log2N-qubit state could then be used for subsequent quantum data processing - for example, to perform rapid comparisons of sequences.

Objective: To study the relationship between infant rotavirus enteritis and breast feeding, with emphasis on early immuno-protection provided by breast feeding as well as later possible hazards with rotavirus carrier mothers. Methods: Stool specimens from 520 infants with diarrhea were screened for rotavirus with colloid gold method. Positive specimens were confirmed with RT-PCR. Results: In local (Qingdao) infants with enteritis, the over-all incidence of rotavirus infection was 31.2%. Positive rate in breast-feeding infants was only 26.8%, being significantly lower than that in bottle-feeding ones (45.2%). The virus infectivity rate in both groups of breast- feeding infants (below 6 months and 7-12 months) was lower than the corresponding rate in the bottle feeding group. However, infant fed from rotavirus carriers had significantly higher fecal positive rate of rotavirus than that in infants fed from non-carriers. Conclusion: (1) At beginning, especially below 6 months, breast-feeding provided important protection again rotavirus enteritis in the infants. (2) certain infections could be transmitted through breast feedings, which deserved closer observation. (authors)

Clinical review: optimizing enteral nutrition for critically ill patients - a simple data-driven formula

Science.gov (United States)

2011-01-01

In modern critical care, the paradigm of 'therapeutic nutrition' is replacing traditional 'supportive nutrition'. Standard enteral formulas meet basic macro- and micronutrient needs; therapeutic enteral formulas meet these basic needs and also contain specific pharmaconutrients that may attenuate hyperinflammatory responses, enhance the immune responses to infection, or improve gastrointestinal tolerance. Choosing the right enteral feeding formula may positively affect a patient's outcome; targeted use of therapeutic formulas can reduce the incidence of infectious complications, shorten lengths of stay in the ICU and in the hospital, and lower risk for mortality. In this paper, we review principles of how to feed (enteral, parenteral, or both) and when to feed (early versus delayed start) patients who are critically ill. We discuss what to feed these patients in the context of specific pharmaconutrients in specialized feeding formulations, that is, arginine, glutamine, antioxidants, certain ω-3 and ω-6 fatty acids, hydrolyzed proteins, and medium-chain triglycerides. We summarize current expert guidelines for nutrition in patients with critical illness, and we present specific clinical evidence on the use of enteral formulas supplemented with anti-inflammatory or immune-modulating nutrients, and gastrointestinal tolerance-promoting nutritional formulas. Finally, we introduce an algorithm to help bedside clinicians make data-driven feeding decisions for patients with critical illness. PMID:22136305

Enteric Protozoa in the Developed World: a Public Health Perspective

Science.gov (United States)

Fletcher, Stephanie M.; Stark, Damien; Harkness, John

2012-01-01

Summary: Several enteric protozoa cause severe morbidity and mortality in both humans and animals worldwide. In developed settings, enteric protozoa are often ignored as a cause of diarrheal illness due to better hygiene conditions, and as such, very little effort is used toward laboratory diagnosis. Although these protozoa contribute to the high burden of infectious diseases, estimates of their true prevalence are sometimes affected by the lack of sensitive diagnostic techniques to detect them in clinical and environmental specimens. Despite recent advances in the epidemiology, molecular biology, and treatment of protozoan illnesses, gaps in knowledge still exist, requiring further research. There is evidence that climate-related changes will contribute to their burden due to displacement of ecosystems and human and animal populations, increases in atmospheric temperature, flooding and other environmental conditions suitable for transmission, and the need for the reuse of alternative water sources to meet growing population needs. This review discusses the common enteric protozoa from a public health perspective, highlighting their epidemiology, modes of transmission, prevention, and control. It also discusses the potential impact of climate changes on their epidemiology and the issues surrounding waterborne transmission and suggests a multidisciplinary approach to their prevention and control.

El maltrato en las personas con discapacidad

OpenAIRE

Revuelta, Lucerga

2014-01-01

El maltrato no solo se realiza por acción sino también por omisión, la indiferencia hacia la persona con discapacidad es una forma de maltrato muy frecuente. Por ejemplo, ignorar y desatender las necesidades de la persona con discapacidad o, al contrario, la sobreprotección son maneras de maltrato. Cuando a un niño con discapacidad el padre o cuidador le hace todo, el niño se siente agredido pues le están incapacitando más de lo que su enfermedad ya lo hace.

Entering the lesbian world in Japan: debut stories.

Kamano, Saori

2005-01-01

Conceiving of a "lesbian community" as the process and/or the end product of a lesbian's going outside herself or her intimate relationship to connect with other lesbians, this paper explores the experiences of lesbians in entering the community in Tokyo, Japan, which lesbians refer to as "community debut." Based on the personal accounts gathered through interviewing 24 women in 2002 in the Tokyo area, this paper examines the personal contexts in which the women entered a lesbian community, which included searching for and defining themselves, accepting themselves, and acting out the new identity to make changes in their lives. Some of the women interviewed were prompted by a need to understand themselves as lesbians. Others with a lesbian identity searched for further affirmation through connecting with "the world of lesbians" beyond their immediate contexts. For some other women interviewed, entering the community was a way to help them start their lives anew by getting out of their previous (married) lives. The paper also specifically touches on the significance of the Internet as a source of information for individual women and as a way of creating a lesbian community, identifying both positive and negative aspects. Although the research reported in this paper leaves for further exploration how boundaries of the communities are negotiated and drawn, the norms of the communities, and conflicts and negotiations among individuals and groups, it has provided one piece of the mosaic of lesbian communities in Japan. The communities, while still largely invisible in the mainstream society, are nonetheless an important part of life, albeit in different ways, of many lesbians. The research process leads the author to anticipate greater visibility of lesbians and lesbian communities in Japan in the not too distant future.

The gastrointestinal (GI) tract, which hosts hundreds of bacteria species, becomes the most exciting organ for the emerging microbiome research. Some of these GI microbes are hostile and cause a variety of diseases. These bacteria colonize in different segments of the GI tract dependent on the local physicochemical and biological factors. Therefore, selectively locating therapeutic or imaging agents to specific GI segments is of significant importance for studying gut microbiome and treating various GI-related diseases. Herein, we demonstrate an enteric micromotor system capable of precise positioning and controllable retention in desired segments of the GI tract. These motors, consisting of magnesium-based tubular micromotors coated with an enteric polymer layer, act as a robust nanobiotechnology tool for site-specific GI delivery. The micromotors can deliver payload to a particular location via dissolution of their enteric coating to activate their propulsion at the target site toward localized tissue penetration and retention.

Background: The nutritional status of cancer patients is frequently impaired already before any therapy starts and may deteriorate even more by radio(chemo)therapy. Methods: This review describes the possibilities and risks of enteral and parenteral nutrition during radiotherapy. The indications of enteral nutrition will be derived from own results. Results: Enteral nutrition is the most preferable way of artificial long-term nutrition. In a prospective non-randomized trial we demonstrated that enteral nutrition via percutaneous endoscopic gastrostomy (PEG) not only improves the anthropometric and biochemical parameters during radio(chemo)therapy but also the quality of life of patients with advanced cancers of the head and neck. Moreover supportive use of megestrolacetate can improve the nutritional status. Parenteral nutrition is only recommended if enteral nutrition is not possible e.g. during radio(chemo)therapy of tumors of the upper gastrointestinal tract. Conclusions: Today adequate nutritional support is feasible during intensive radio(chemo)therapy. (orig.) [Deutsch] Hintergrund: Der Ernaehrungsstatus von Tumorpatienten ist haeufig bereits vor jeder antitumoroesen Therapie reduziert und kann sich durch die notwendige Radio(chemo)therapie weiter verschlechtern. Methode: Im Rahmen dieses Uebersichtsartikels werden die Moeglichkeiten und Risiken der enteralen und parenteralen Ernaehrung waehrend einer Radiotherapie besprochen. Die Indikationen der enteralen Ernaehrung werden anhand von eigenen Ergebnissen begruendet. Ergebnisse: Die Langzeiternaehrung wird am besten ueber einen enteralen Zugang durchgefuehrt. In einer prospektiven, nichtrandomisierten Studie konnten wir zeigen, dass eine enterale Ernaehrung mittels perkutaner endoskopisch kontrollierter Gastrostomie (PEG) nicht nur die anthropometrischen und biochemischen Parameter waehrend einer Radio(chemo)therapie verbessert, sondern auch die Lebensqualitaet.

2012-08-01

Full Text Available Abstract Background Ageing is associated with gastrointestinal dysfunction, which can have a major impact on quality of life of the elderly. A number of changes in the innervation of the gut during ageing have been reported, including neuronal loss and degenerative changes. Evidence indicates that reactive oxygen species (ROS are elevated in ageing enteric neurons, but that neurotrophic factors may reduce generation of neuronal ROS. Two such factors, glial cell line derived neurotrophic factor (GDNF and neurotrophin-3 (NT-3 have also been found to protect enteric neurons against oxidative stress induced cell death of enteric ganglion cells in vitro. We have investigated the possible roles of neurotrophic factors further, by examining their expression in the gut during ageing, and by analysing their effects on antioxidant enzyme production in cultures of enteric ganglion cells. Results Analysis of the expression of GDNF and its receptors c-Ret and GFR α − 1 in rat gut by RT-PCR showed that expression continues throughout life and into ageing, in both ad libitum(AL and calorically-restricted (CR animals. Levels of expression of GDNF and GFR α − 1 were elevated in 24 month AL animals compared to 24 month CR animals, and to 24 CR and 6 month control animals respectively. The related factor Neurturin and its receptor GFR α − 2 were also expressed throughout life, the levels of the GFR – α-2(b isoform were reduced in 24 m AL animals. Immunolabelling showed that c-Ret and GFR α − 1 proteins were expressed by myenteric neurons in ageing animals. GDNF, but not NT-3, was found to increase expression of Cu/Zn superoxide dismutase and catalase by cultured enteric ganglion cells. Conclusions The neurotrophic factors GDNF and neurturin and their receptors continue to be expressed in the ageing gut. Changes in the levels of expression of GDNF , GFR α-1 and GFR α-2(b isoform occurred in 24 m AL animals. GDNF, but not

In order to improve the bioavailability of rifampicin (RIF) from rifampicin and isoniazid (INH) combination formulations, the physicochemical characteristics of RIF, stability of RIF in different pH buffers in the presence of INH, as well as the effect of particle size of RIF materials on the dissolution rate were investigated. On the basis of the above examinations, enteric-coated tablets for RIF and INH combinations were designed and prepared. RIF showed low solubility and high apparent distribution coefficient in the intestinal pH (pH 4.0-7.4). With the decrease in pH, the degradation of RIF increase and the presence of INH deepen the degradation. Enteric-coated tablets were prepared after grinding the RIF materials by dry granulation technique. The pharmacokinetics of RIF and INH of self-made enteric-coated tablets in dogs were studied by comparing with the reference tablets. The AUC(0-48) of RIF in both reference and test tablets were 304.77 ± 42.27 and 353.79 ± 31.63 µg·h·mL(-1), respectively. The AUC(0-48) of INH in both reference and test tablets were 17.14 ± 8.59 and 19.62 ± 10.57 µg·h·mL(-1), respectively. Enteric-coated tablets may minimize the decomposition of RIF in gastrointestinal tract and improve the bioavailability.

Oleuropein is a phenolic compound of olive leaves. Enteric bacterial flora is very important for human health and diet is a directly affecting factor of enteric bacterial flora composition. In this study, it was hypothesized that oleuropein could reduce total aerobic bacterial count in rat caecal flora. Twenty adult, male, Wistar albino rats were randomly divided into two groups. Group C (n=10) was fed with standard rat chow and water for 30 days. Group O (n=10) received olive leaf extract 20 mg/kg/day by intragastric gavage in addition to standard rat chow and water for 30 days. One gram of caecal content was collected from each rat and then consecutive 10-fold serial dilutions were prepared with a final concentration of 10-8. Then 0.1 ml of each dilution were spread onto the surfaces of Plate Count Agar and Violet Red Bile Glucose Agar to enumerate the aerobic enteric bacteria. Total aerobic bacterial counts of Group O were significantly lower than of Group C in all agar plates inoculated with ceacal samples for every dilution (pbacterial translocation by reducing enteric bacterial counts (Tab. 1, Ref. 32).

La mayor parte de los tumores foliculares son benignos, pero en los últimos años se han publicado casos aislados de tumores anexiales con características de malignidad y con una gran agresividad local siendo en principio tumores que se consideraban benignos. Creemos que este tumor está siendo infradiagnosticado, y como consecuencia, infratratado al ser confundido con otros tumores malignos originados en la piel, como el carcinoma basocelular y sobre todo con el carcinoma epidermoide, en parte por poca documentación y por la dificultad para su diagnóstico anatomopatológico. Presentamos un caso de carcinoma tricofolicular en cuero cabelludo en una mujer de 51 años de edad que rápidamente invade sistema nervioso central y que en solo 3 meses metastatiza a pulmón.

Multidrug resistance in enteric and other gram-negative bacteria.

Science.gov (United States)

George, A M

1996-05-15

In Gram-negative bacteria, multidrug resistance is a term that is used to describe mechanisms of resistance by chromosomal genes that are activated by induction or mutation caused by the stress of exposure to antibiotics in natural and clinical environments. Unlike plasmid-borne resistance genes, there is no alteration or degradation of drugs or need for genetic transfer. Exposure to a single drug leads to cross-resistance to many other structurally and functionally unrelated drugs. The only mechanism identified for multidrug resistance in bacteria is drug efflux by membrane transporters, even though many of these transporters remain to be identified. The enteric bacteria exhibit mostly complex multidrug resistance systems which are often regulated by operons or regulons. The purpose of this review is to survey molecular mechanisms of multidrug resistance in enteric and other Gram-negative bacteria, and to speculate on the origins and natural physiological functions of the genes involved.

A systematic review of zoonotic enteric parasitic diseases among nomadic and pastoral people.

Directory of Open Access Journals (Sweden)

Amber N Barnes

Full Text Available Zoonotic enteric parasites are ubiquitous and remain a public health threat to humans due to our close relationship with domestic animals and wildlife, inadequate water, sanitation, and hygiene practices and diet. While most communities are now sedentary, nomadic and pastoral populations still exist and experience unique exposure risks for acquiring zoonotic enteric parasites. Through this systematic review we sought to summarize published research regarding pathogens present in nomadic populations and to identify the risk factors for their infection.Using systematic review guidelines set forth by PRISMA, research articles were identified, screened and summarized based on exclusion criteria for the documented presence of zoonotic enteric parasites within nomadic or pastoral human populations. A total of 54 articles published between 1956 and 2016 were reviewed to determine the pathogens and exposure risks associated with the global transhumance lifestyle.The included articles reported more than twenty different zoonotic enteric parasite species and illustrated several risk factors for nomadic and pastoralist populations to acquire infection including; a animal contact, b food preparation and diet, and c household characteristics. The most common parasite studied was Echinococcosis spp. and contact with dogs was recognized as a leading risk factor for zoonotic enteric parasites followed by contact with livestock and/or wildlife, water, sanitation, and hygiene barriers, home slaughter of animals, environmental water exposures, household member age and sex, and consumption of unwashed produce or raw, unprocessed, or undercooked milk or meat.Nomadic and pastoral communities are at risk of infection with a variety of zoonotic enteric parasites due to their living environment, cultural and dietary traditions, and close relationship to animals. Global health efforts aimed at reducing the transmission of these animal-to-human pathogens must incorporate

A new, more palatable formulation of 10% enrofloxacin enteric-coated granules was investigated to evaluate the pharmacokinetic effect in plasma, the residue elimination in tissues and the clinical efficacy against Actinobacillus pleuropneumonia (APP) and Mycoplasam suis (MS) in pigs. In this study, the enrofloxacin concentrations in plasma and tissues were detected using high-performance liquid chromatography with phosphate buffer (pH = 3) and acetonitrile. The pharmacokinetics and elimination of enrofloxacin enteric-coated granules were performed after oral administration at a single dose of 10 mg/kg body weight (bw) and 5 mg/kg twice per day for 5 consecutive days, respectively. The in vivo antibacterial efficacy and clinical effectiveness of enrofloxacin enteric-coated granules against APP and MS were assayed at 2.5, 5, 10 mg/kg, compared with tiamulin (8 mg/kg) based on establishment of APP and MS infection models. 56 APP strains were selected and tested for in vitro antibacterial activity of enrofloxacin enteric-coated granules. The main parameters of elimination half-life (t 1/2β ), T max , and area under the curve (AUC) were 14.99 ± 4.19, 3.99 ± 0.10, and 38.93 ± 1.52 μg h/ml, respectively, revealing that the enrofloxacin concentration remained high and with a sustainable distribution in plasma. Moreover, the analysis on the evaluation of enrofloxacin and ciprofloxacin in muscle, fat, liver and kidney showed that the recovery were more than 84% recovery in accordance with the veterinary drug residue guidelines of United States pharmacopeia, and the withdrawal periods were 4.28, 3.81, 4.84, and 3.51 days, respectively, suggesting that the withdrawal period was 5 d after oral administration of 5 mg/kg twice per day. The optimal dosage of enrofloxacin enteric-coated granules against APP and MS was 5 mg/kg, with over 90% efficacy, which was significantly different ( p enrofloxacin enteric-coated granules had significant potential for treating APP and MS

Necrotizing enterocolitis (NEC) remains one of the most common underlying diagnoses of short bowel syndrome (SBS) in children. The relationship between the etiology of SBS and ultimate enteral autonomy has not been well studied. This investigation sought to evaluate the rate of achievement of enteral autonomy in SBS patients with and without NEC. Following IRB approval, 109 patients (2002-2014) at a multidisciplinary intestinal rehabilitation program were reviewed. The primary outcome evaluated was achievement of enteral autonomy (i.e. fully weaning from parenteral nutrition). Patient demographics, primary diagnosis, residual small bowel length, percent expected small bowel length, median serum citrulline level, number of abdominal operations, status of the ileocecal valve (ICV), presence of ileostomy, liver function tests, and treatment for bacterial overgrowth were recorded for each patient. Median age at PN onset was 0 weeks [IQR 0-0]. Median residual small bowel length was 33.5 cm [IQR 20-70]. NEC was present in 37 of 109 (33.9%) of patients. 45 patients (41%) achieved enteral autonomy after a median PN duration of 15.3 [IQR 7.2-38.4]months. Overall, 64.9% of patients with NEC achieved enteral autonomy compared to 29.2% of patients with a different primary diagnosis (p=0.001, Fig. 1). Patients with NEC remained more likely than those without NEC to achieve enteral autonomy after two (45.5% vs. 12.0%) and four (35.7% vs. 6.3%) years on PN (Fig. 1). Logistic regression analysis demonstrated the following parameters as independent predictors of enteral autonomy: diagnosis of NEC (pChildren with SBS because of NEC have a significantly higher likelihood of fully weaning from parenteral nutrition compared to children with other causes of SBS.

Full Text Available We aimed to evaluate the potential virulence of Klebsiella isolates from enteral diets in hospitals, to support nosocomial infection control measures, especially among critical-care patients. Phenotypic determination of virulence factors, such as capsular expression on the external membrane, production of aerobactin siderophore, synthesis of capsular polysaccharide, hemolytic and phospholipase activity, and resistance to antibiotics, which are used therapeutically, were investigated in strains of Klebsiella pneumoniae and K. oxytoca. Modular industrialized enteral diets (30 samples as used in two public hospitals were analyzed, and Klebsiella isolates were obtained from six (20% of them. The hypermucoviscous phenotype was observed in one of the K. pneumoniae isolates (6.7%. Capsular serotypes K1 to K6 were present, namely K5 and K4. Under the conditions of this study, no aerobactin production, hemolytic activity or lecithinase activity was observed in the isolates. All isolates were resistant to amoxicillin and ampicillin and sensitive to cefetamet, imipenem, chloramphenicol, gentamicin and sulfamethoxazole-trimethoprim. Most K. pneumoniae isolates (6/7, 85.7% from hospital B presented with a higher frequency of resistance to the antibiotics tested in this study, and multiple resistance to at least four antibiotics (3/8; 37.5% compared with isolates from Hospital A. The variations observed in the antibiotic resistance profiles allowed us to classify the Klebsiella isolates as eight antibiotypes. No production of broad-spectrum β-lactamases was observed among the isolates. Our data favor the hypothesis that Klebsiella isolates from enteral diets are potential pathogens for nosocomial infections.

Full Text Available Objective: To explore the changes and clinical significance of liver function and myocardial zymogram in children with rotavirus (RV enteritis. Methods: A total of 70 children with RV enteritis who were admitted in our hospital were included in the study and served as the observation group. The liver function and myocardial zymogram before and after treatment were detected. The proportion of RV enteritis children with liver and myocardial damage was calculated. The effect of dehydration on the liver function and myocardial zymogram in children with RV enteritis was analyzed. A total of 65 children with non-RV enteritis who were admitted in our hospital at the same stage were served as the control group. Results: The serum ALT, AST, CK, CK-MB, LDH, and α-HBDH levels, and liver myocardial damage children proportion in the observation group were significantly higher than those in the control group (P<0.05. The serum ALT, AST, CK, CK-MB, LDH, and α-HBDH levels in the observation group were significantly elevated with the acceleration of dehydration degree (P<0.05. In the observation group, 45 children had liver and myocardial damage, whose ALT, AST, CK, CKMB, LDH, and α-HBDH levels after treatment were significantly reduced when compared with before treatment (P<0.05. Conclusions: Early detection of liver function and myocardial zymogram can accurately reflect the condition in children with RV enteritis, which can provide an evidence for the formulation of clinical treatment protocol.

Full Text Available Abstract The mission of the Armed Forces Health Surveillance Center, Division of Global Emerging Infections Surveillance and Response System (AFHSC-GEIS is to support global public health and to counter infectious disease threats to the United States Armed Forces, including newly identified agents or those increasing in incidence. Enteric diseases are a growing threat to U.S. forces, which must be ready to deploy to austere environments where the risk of exposure to enteropathogens may be significant and where routine prevention efforts may be impractical. In this report, the authors review the recent activities of AFHSC-GEIS partner laboratories in regards to enteric disease surveillance, prevention and response. Each partner identified recent accomplishments, including support for regional networks. AFHSC/GEIS partners also completed a Strengths, Weaknesses, Opportunities and Threats (SWOT survey as part of a landscape analysis of global enteric surveillance efforts. The current strengths of this network include excellent laboratory infrastructure, equipment and personnel that provide the opportunity for high-quality epidemiological studies and test platforms for point-of-care diagnostics. Weaknesses include inconsistent guidance and a splintered reporting system that hampers the comparison of data across regions or longitudinally. The newly chartered Enterics Surveillance Steering Committee (ESSC is intended to provide clear mission guidance, a structured project review process, and central data management and analysis in support of rationally directed enteric disease surveillance efforts.

2015-04-01

Full Text Available The aim of this review is to provide a global perspective of Home Enteral Tube Feeding (HETF and to outline some of the challenges of home enteral nutrition (HEN provisions. It is well established that the number of patients on HETF is on the increase worldwide due to advances in technology, development of percutaneous endoscopic gastrostomy techniques, and the shift in care provisions from acute to community settings. While the significance of home enteral nutrition in meeting the nutritional requirements of patients with poor swallowing reflexes and those with poor nutritional status is not in doubt, differences exist in terms of funding, standards, management approaches and the level of infrastructural development across the world. Strategies for alleviating some of the challenges militating against the effective delivery of HETF including the development of national and international standards, guidelines and policies for HETF, increased awareness and funding by government at all levels were discussed. Others, including development of HEN services, which should create the enabling environment for multidisciplinary team work, clinical audit and research, recruitment and retention of specialist staff, and improvement in patient outcomes have been outlined. However, more research is required to fully establish the cost effectiveness of the HEN service especially in developing countries and to compare the organization of HEN service between developing and developed countries.

2011-01-01

Background: Diarrhoea is a serious threat all over the world with great economic implications especially evident in the developing world. This study was aimed at determining in vitro efficacy of Zinc (Zn) against common enteric bacterial pathogens. Method: A total of 100 bacterial enteric pathogens: Salmonellae (n=16), enteropathogenic Escherichia coli (EPEC) (n=26), Shigellae (n=28) and Vibrio cholerae (n=30) were isolated from diarrhoeal stool specimens at Department of Microbiology, Armed Forces Institute of Pathology Rawalpindi during April 2009 to Jan 2010. These isolates were tested against various concentrations of Zn supplemented in Mueller Hinton (MH) agar using a multipoint inoculator. A minimum inhibitory concentration of active Zn in ZnSO/sub 4/.7H/sub 2/O ranging from 0.03 mg/ml to 1 mg/ml was used. Results: Zn completely inhibited the growth of all the tested pathogens and most of them were inhibited at a concentration of 0.06 mg/ml to 0.5 mg/ml of Zn. Conclusions: Zinc has an excellent antibacterial activity against enteric bacterial pathogens common in our setup which may provide basis for treatment of diarrhoea. Clinical study based on these findings is recommended. (author)

Enteric fever in high-income countries is diagnosed mainly in patients returning from endemic countries. We assess the clinical, microbiological, and prognosis aspects of enteric fever in 2 Spanish tertiary hospitals. A retrospective observational study was conducted at Vall d'Hebron University Hospital and Ramón y Cajal University Hospital in Spain. We reviewed medical records of all patients who were diagnosed with enteric fever from January 2000 to January 2014 at these hospitals. We identified 47 patients with enteric fever episodes. According to their travel history, 35 (74.5%) patients had travelled to highly endemic countries. Imported enteric fever was acquired mainly in Asia (70.3%). Imported infections were implicated in travelers (48.6%), visiting friends and relatives (40%) and immigrants (11.4%). We found that 12 patients were diagnosed with enteric fever without a travel history (autochthonous infection). The resistance profile of the isolates showed decreased ciprofloxacin susceptibility in 66.7% of the imported group and 8.3% of the autochthonous group (P = 0.001). Salmonella strains from patients returning from Asia had an increased risk of having decreased ciprofloxacin susceptibility (odds ratio, 52.25; 95% confidence interval: 8.6-317.7). Patients with imported enteric fever are at higher risk for having a Salmonella strain with decreased ciprofloxacin susceptibility, especially in patients returning from Asia. Initial treatment with third-generation cephalosporin or azithromycin is strongly recommended until a drug-susceptibility test is available. Prevention strategies such as pretravel counseling and immunization before travel may be beneficial.

Esquivel, A.; Raga, A. C.; RodrIguez-Gonzalez, A.; Lopez-Camara, D.; Velazquez, P. F.; Canto, J.; De Colle, F.

2010-01-01

We model the cometary structure around Mira as the interaction of an asymptotic giant branch stellar wind from Mira A with a streaming environment. Our simulations introduce the following new element: we assume that after 200 kyr of evolution in a dense environment, Mira entered the Local Bubble (low-density coronal gas). As Mira enters the bubble, the head of the comet expands quite rapidly, while the tail remains well collimated for a >100 kyr timescale. The result is a broad-head/narrow-tail structure that resembles the observed morphology of Mira's comet. The simulations were carried out with our new adaptive grid code WALICXE, which is described in detail.

Arbuckle, Melissa R; Luo, Sean X; Pincus, Harold Alan; Gordon, Joshua A; Chung, Joyce Y; Chavez, Mark; Oquendo, Maria A

2018-06-01

The goal of this study was to identify trends in MD/PhD graduates entering psychiatry, to compare these trends with other specialties, and to review strategies for enhancing the physician-scientist pipeline. Data on 226,588 medical students graduating from Liaison Committee on Medical Education accredited programs between 1999 and 2012 (6626 MD/PhDs) were used to evaluate the number, percentage, and proportion of MD/PhDs entering psychiatry in comparison with other specialties (neurology, neurosurgery, internal medicine, family medicine, and radiation oncology). Linear regression and multiple linear regression determined whether these values increased over time and varied by sex. Over 14 years, an average of 18 MD/PhDs (range 13-29) enrolled in psychiatry each year. The number of MD/PhDs going into psychiatry significantly increased, although these gains were modest (less than one additional MD/PhD per year). The proportion of students entering psychiatry who were MD/PhDs varied between 2.9 and 5.9 per 100 residents, with no significant change over time. There was also no change in the percentage of MD/PhDs entering psychiatry from among all MD/PhD graduates. The rate of increase in the number of MD/PhDs going into psychiatry did not differ significantly from other specialties except for family medicine, which is decreasing. The rate of MD/PhDs going into psychiatry was higher for women, suggesting closure of the sex gap in 17 years. Despite the increase in the number of MD/PhDs entering psychiatry, these numbers remain low. Expanding the cohort of physician-scientists dedicated to translational research in psychiatry will require a multipronged approach.

Silva, Camila F A; de Vasconcelos, Simone G; da Silva, Thales A; Silva, Flávia M

2018-01-26

The aim of this study was to systematically review the effect of permissive underfeeding/trophic feeding on the clinical outcomes of critically ill patients. A systematic review of randomized clinical trials to evaluate the mortality, length of stay, and mechanical ventilation duration in patients randomized to either hypocaloric or full-energy enteral nutrition was performed. Data sources included PubMed and Scopus and the reference lists of the articles retrieved. Two independent reviewers participated in all phases of this systematic review as proposed by the Cochrane Handbook, and the review was reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A total of 7 randomized clinical trials that included a total of 1,717 patients were reviewed. Intensive care unit length of stay and mechanical ventilation duration were not statistically different between the intervention and control groups in all randomized clinical trials, and mortality rate was also not different between the groups. In conclusion, hypocaloric enteral nutrition had no significantly different effects on morbidity and mortality in critically ill patients when compared with full-energy nutrition. It is still necessary to determine the safety of this intervention in this group of patients, the optimal amount of energy provided, and the duration of this therapy. © 2018 American Society for Parenteral and Enteral Nutrition.

Full Text Available Il saggio affronta il tema: quali idee pedagogiche hanno influenzato la progettazione dei laboratori "Giocare con l’arte", ideati da Bruni Munari negli anni Settanta e destinati a trasformare profondamente il modo d’intendere la didattica museale e l’educazione estetico-artistica. L’ipotesi dell’autrice è che questi laboratori riprendano alcuni principi dell’attivismo pedagogico, a cui Munari non fa però esplicito riferimento nei suoi scritti. Per questo motivo, il saggio cerca di ricostruire gli incontri più significativi che possono aver mediato l’approccio alla didattica attiva, soffermandosi in particolare sui rapporti di collaborazione intessuti da Munari con lo scrittore Gianni Rodari e con il pedagogista Giovanni Belgrano. Sia Rodari, sia Belgrano erano legati – seppure con diverse modalità – al Movimento di Cooperazione Educativa, che si proponeva di rinnovare la scuola italiana ispirandosi alla pedagogia deweyana. Attraverso la loro mediazione, Munari può essersi avvicinato all’attivismo, di cui condivideva peraltro molteplici assunti: dall’esigenza di promuovere la creatività del bambino, mediante la sperimentazione di materiali e tecniche, alla concezione dell’educatore come animatore delle attività volte alla padronanza dei saperi. In tal senso, il saggio si propone anche di mostrare la continuità esistente tra questa linea teorica e la riflessione sulla democratizzazione dell’arte intrapresa da Munari già nel 1948, con la fondazione – insieme ad altri artisti – del Movimento Arte Concreta.

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.

Full Text Available Children suffer the highest burden of enteric fever among populations in South Asian countries. The clinical features are non–specific, vary in populations, and are often difficult to distinguish clinically from other febrile illnesses, leading to delayed or inappropriate diagnosis and treatment. We undertook a systematic review to assess the clinical profile and laboratory features of enteric fever across age groups, economic regions, level of care and antibiotic susceptibility patterns.

Ingested glucose is detected by specialized sensors in the enteric/hepatoportal vein, which send neural signals to the brain, which in turn regulates key peripheral tissues. Hence, impairment in the control of enteric-neural glucose sensing could contribute to disordered glucose homeostasis. The aim of this study was to determine the cells in the brain targeted by the activation of the enteric glucose-sensing system. We selectively activated the axis in mice using a low-rate intragastric glucose infusion in wild-type and glucagon-like peptide-1 (GLP-1) receptor knockout mice, neuropeptide Y-and proopiomelanocortin-green fluorescent protein-expressing mice, and high-fat diet diabetic mice. We quantified the whole-body glucose utilization rate and the pattern of c-Fos positive in the brain. Enteric glucose increased muscle glycogen synthesis by 30% and regulates c-Fos expression in the brainstem and the hypothalamus. Moreover, the synthesis of muscle glycogen was diminished after central infusion of the GLP-1 receptor (GLP-1Rc) antagonist Exendin 9-39 and abolished in GLP-1Rc knockout mice. Gut-glucose-sensitive c-Fos-positive cells of the arcuate nucleus colocalized with neuropeptide Y-positive neurons but not with proopiomelanocortin-positive neurons. Furthermore, high-fat feeding prevented the enteric activation of c-Fos expression. We conclude that the gut-glucose sensor modulates peripheral glucose metabolism through a nutrient-sensitive mechanism, which requires brain GLP-1Rc signaling and is impaired during diabetes.

Genetic aspects of enteric methane emission in ruminants livestock

2013-10-01

Full Text Available This review summarizes the importance of enteric methane (CH4 emission in ruminants and relevant to the current on knowledge relevant to genetic aspects of enteric CH4 production, highlighting future research needs and directions. Global average temperature has increased by about 0.7°C in the last century. The Intergovernmental Panel on Climate Change (IPCC reported that anthropogenic greenhouse gases (GHG, including carbon dioxide (CO2, CH4, nitrous oxide (N2O and halocarbons, have been responsible for most of the observed temperature increase since the middle of the twentieth century. Agriculture, particularly livestock, is increasingly being recognized as both a contributor to the process and a potential victim of it. Policy interventions and technical solutions are required to address both the impact of livestock production on climate change and the effects of climate change on livestock production. Food and Agriculture Organization (FAO, declared that in the next 50 years, the world’s farmers will be called upon to produce more food than has been produced in the past 10,000 years, and to do so in environmentally sustainable ways. Therefore, the GHG reduction should be treated as a public good. The United States congress is prospecting to define a price on GHG emissions. Limiting the concentration of CO2 and other GHG in Earth’s atmosphere requires a technological and economic revolution. A cost-effective way could be the genetic improvement of livestock, which produces permanent and cumulative changes in performance. Animal variation in enteric CH4 emission has been reported in the literature, providing potential for improvement through genetic selection.

Full Text Available OBJETIVO: Avaliar a adequação da dieta enteral, em termos de micronutrientes e energia e identificar fatores interferentes na progressão da dieta enteral prescrita a adultos hospitalizados em um hospital geral de alta complexidade. MÉTODOS: Entre junho de 2004 e maio de 2005, adultos internados em um hospital de alta complexidade do sul do Brasil foram avaliados quanto às suas características clínicas e da prescrição da nutrição enteral. As características da nutrição enteral foram avaliadas e comparadas às recomendações diárias de ingestão, obtendo-se o percentual de adequação de nutrientes prescritos na dieta enteral em relação aos valores de recomendação para cada paciente. Os fatores associados à prescrição de energia foram identificados por meio de Regressão Linear Múltipla. RESULTADOS: Foram acompanhados 230 pacientes em uso de nutrição enteral. As recomendações diárias foram alcançadas satisfatoriamente para vitaminas hidrossolúveis (exceto ácido fólico, lipossolúveis (exceto vitamina D e minerais (exceto cálcio. Em média, as prescrições iniciais de nutrição enteral ofereceram 24,0kcal/kg/dia (desvio-padrão=10,8, e valores mínimo e máximo de 4,3 a 69,2, e progrediram até 28,4kcal/kg/dia (desvio-padrão=11,8, valores mínimo e máximo de 1,4 a 69,2. A recomendação de 25 a 35kcal/kg/dia foi prescrita para 32,6% dos pacientes. Para 15,7% dos pacientes foram prescritas acima de 40kcal/kg/dia. Somente o índice de massa corporal e o número de dias de hospitalização, ajustados para a quantidade de energia já inicialmente prescrita, associaram-se de forma independente à prescrição energética final. CONCLUSÃO: Pequena proporção das prescrições esteve adequada em relação à quantidade de energia, e a progressão da dieta enteral ocorreu independentemente das características clínicas dos pacientes.OBJECTIVE: To asses the adequacy of enteral diet, in terms of micronutrients and

Size distribution of air bubbles entering the brain during cardiac surgery.

Directory of Open Access Journals (Sweden)

Emma M L Chung

Full Text Available Thousands of air bubbles enter the cerebral circulation during cardiac surgery, but whether high numbers of bubbles explain post-operative cognitive decline is currently controversial. This study estimates the size distribution of air bubbles and volume of air entering the cerebral arteries intra-operatively based on analysis of transcranial Doppler ultrasound data.Transcranial Doppler ultrasound recordings from ten patients undergoing heart surgery were analysed for the presence of embolic signals. The backscattered intensity of each embolic signal was modelled based on ultrasound scattering theory to provide an estimate of bubble diameter. The impact of showers of bubbles on cerebral blood-flow was then investigated using patient-specific Monte-Carlo simulations to model the accumulation and clearance of bubbles within a model vasculature.Analysis of Doppler ultrasound recordings revealed a minimum of 371 and maximum of 6476 bubbles entering the middle cerebral artery territories during surgery. This was estimated to correspond to a total volume of air ranging between 0.003 and 0.12 mL. Based on analysis of a total of 18667 embolic signals, the median diameter of bubbles entering the cerebral arteries was 33 μm (IQR: 18 to 69 μm. Although bubble diameters ranged from ~5 μm to 3.5 mm, the majority (85% were less than 100 μm. Numerous small bubbles detected during cardiopulmonary bypass were estimated by Monte-Carlo simulation to be benign. However, during weaning from bypass, showers containing large macro-bubbles were observed, which were estimated to transiently affect up to 2.2% of arterioles.Detailed analysis of Doppler ultrasound data can be used to provide an estimate of bubble diameter, total volume of air, and the likely impact of embolic showers on cerebral blood flow. Although bubbles are alarmingly numerous during surgery, our simulations suggest that the majority of bubbles are too small to be harmful.

Full Text Available A new, more palatable formulation of 10% enrofloxacin enteric-coated granules was investigated to evaluate the pharmacokinetic effect in plasma, the residue elimination in tissues and the clinical efficacy against Actinobacillus pleuropneumonia (APP and Mycoplasam suis (MS in pigs. In this study, the enrofloxacin concentrations in plasma and tissues were detected using high-performance liquid chromatography with phosphate buffer (pH = 3 and acetonitrile. The pharmacokinetics and elimination of enrofloxacin enteric-coated granules were performed after oral administration at a single dose of 10 mg/kg body weight (bw and 5 mg/kg twice per day for 5 consecutive days, respectively. The in vivo antibacterial efficacy and clinical effectiveness of enrofloxacin enteric-coated granules against APP and MS were assayed at 2.5, 5, 10 mg/kg, compared with tiamulin (8 mg/kg based on establishment of APP and MS infection models. 56 APP strains were selected and tested for in vitro antibacterial activity of enrofloxacin enteric-coated granules. The main parameters of elimination half-life (t1/2β, Tmax, and area under the curve (AUC were 14.99 ± 4.19, 3.99 ± 0.10, and 38.93 ± 1.52 μg h/ml, respectively, revealing that the enrofloxacin concentration remained high and with a sustainable distribution in plasma. Moreover, the analysis on the evaluation of enrofloxacin and ciprofloxacin in muscle, fat, liver and kidney showed that the recovery were more than 84% recovery in accordance with the veterinary drug residue guidelines of United States pharmacopeia, and the withdrawal periods were 4.28, 3.81, 4.84, and 3.51 days, respectively, suggesting that the withdrawal period was 5 d after oral administration of 5 mg/kg twice per day. The optimal dosage of enrofloxacin enteric-coated granules against APP and MS was 5 mg/kg, with over 90% efficacy, which was significantly different (p < 0.05 to the 2.5 mg/kg group, but not to the 10 mg/kg group or the positive

Therapeutic effects of Glucagon-Like Peptide-2 on experimental radiation enteritis in rat

International Nuclear Information System (INIS)

Torres, S.

2007-01-01

Radiation enteritis in patients treated by abdominal and pelvic radiotherapy is characterized by acute mucosal disruption and chronic intestinal fibrosis. Using a model of localized intestinal irradiation in the rat, we showed remote intestinal dysfunction outside the irradiation field along the whole gut, probably associated with perturbations in the systems regulating intestinal functions. Based on the hypothesis of consequential late effects, acute administration of Glucagon-Like Peptide-2, a growth factor with specific trophic effect on the intestinal mucosa, limited the apparition of both acute and chronic radiation enteritis. This suggests that therapeutic strategies targeting the severity of acute tissue damage may also limit chronic sequelae. The study of GLP-2 effects on epithelial cells in co-culture with either subepithelial myo-fibroblasts or enteric nervous system emphasized the problem of the modelization of complex systems in vitro, and suggested a synergic action from these different actors in vivo.

Malignant gastric outlet obstruction can be treated by means of enteral stenting or surgical gastrojejunalanatomosis. We evaluated in a prospective and multicentre study the efficacy of the enteral stent on food intake, the quality of life impact, and the relationship between efficacy and determined clinical and technical parameters. Seventy one patients affected by symptoms arising from gastroduodenal obstruction due to malignant tumors, with criteria of irresecability, metastatic disease or very high surgical risk, were treated by means of self expanding metal stents. We used the GOOSS index to evaluate efficacy, and the Euro Qol-5D index to evaluate quality of life. Before stenting patients with GOOSS 0 and 1 were 68 (98.5%). After stenting patients with GOOSS 2 and 3 (semisolid and solid food) were 58 (84,1%) (P<.0001). The Euro Qol-5D index measured before and a month after stenting were 10.17 and 10.04 respectively (P=.6). The median survival was 91 days (9-552). The enteral stents for localised tumors in the duodenum and the gastrojejunalanastomosis were effective in 26 patients (70.2%) and 13 patients respectively (86.6%), while the enteral stents of tumors in the antrum were effective in only 5 patients (29.4%). The palliative treatment of malignant gastric outlet obstruction with a uncovered metal stent produces a significant improvement of oral food intake and maintains the overall quality of life index. The antral localization is associated with a lower efficacy of the procedure. Copyright © 2010 Elsevier España, S.L. All rights reserved.

The aim of this scoping literature review was to identify the factors related to nursing students' readiness to enter working life. The literature search was carried out in autumn 2017 in PubMed and CINAHL databases. The studies selected for this review (n = 17) were analyzed thematically with inductive content analysis. Four subthemes that were combined into two main factors related to nursing students' readiness to enter working life were found. The main factors found were 1) educational factors and 2) personal factors. Educational factors consisted of professional competence and clinical practice, while personal factors consisted of nursing students' background and feelings. Some nursing students tend to feel insecure about entering working life as a newly graduated nurse. This literature review also supports the importance of clinical practice periods in nursing education and for readiness for working life. Nurse education needs to ensure clinical practice periods which support nursing students' professional growth. Further research is needed on how the factors related to nursing students' readiness to enter working life correlate with each other. Particularly, the association between competence, readiness and positive feelings towards graduation needs further investigation. Copyright © 2018 Elsevier Ltd. All rights reserved.

A patient aged 8 in whom the clinical and electroencephalographic criteria of epilepsy of childhood with occipital paroxysms are present is studied in this paper. Emphasis is made on the apparently benign evolution of this syndrome.

Roth, Jay E; Coleman, Christopher Lance

2008-01-01

The objective of this literature review is to describe the perceived or real barriers to men seeking a career in nursing, and to suggest strategies for ameliorating barriers. A literature search exploring barriers existing for men pursuing nursing was conducted. Although the literature underscored the structure of nursing has changed substantially over the last fifty years, these changes have not always provoked a change in the public's perception of nursing. Barriers for men entering nursing still exist. Implications for gender diversity in nursing are discussed. Strategies for decreasing barriers experienced by males entering nursing are warranted.
