    2007-01-01

    Introgen and its wholly owned European subsidiary Gendux AB are developing an adenoviral p53 gene therapy as a treatment for cancer in the US and Europe, respectively. Phase III trials in patients with head and neck cancer are ongoing, and a number of clinical trials in other cancer indications have been completed. INGN 201 is being reviewed by the EMEA for approval in Li-Fraumeni syndrome (LFS) under the provisions of exceptional circumstance; the therapy is available on a compassionate use basis to eligible LFS cancer patients under a protocol authorised by the US FDA. The p53 tumour suppressor gene is deleted or mutated in many tumour cells and is one of the most frequently mutated genes in human tumours. The p53 protein is one of the most intricate elements in the apoptotic signalling cascade, and a mutation in the gene encoding it is believed to result in a decreased ability of a cell to apoptose. Thus replacing this gene via adenovirally-mediated p53 gene therapy is hoped to result in increased apoptosis where it is administered.INGN 201 is available for licensing, although Introgen favours retaining partial or full rights to the therapy in the US. Introgen entered into a license agreement with The University of Texas System and MD Anderson Cancer Center in 1994. The technologies licenced include p53 and fus1 (INGN 401). The collaboration has yielded exclusive patent and licensing rights to numerous technologies. Introgen entered into a collaboration with Rhône-Poulenc Rorer Pharmaceuticals (now sanofi-aventis) to develop therapeutics based on p53 inhibition in October 1994. However, in June 2001 this relationship was restructured and Introgen assumed responsibility for the worldwide development of all p53 products including INGN 201, and acquired all marketing and commercialisation rights with respect to those products. Introgen initiated two phase III trials in head and neck cancer (in June 2000 and May 2001) at about 80 sites in the US, Canada and Europe

    2003-01-01

    Introgen's adenoviral p53 gene therapy [INGN 201, ADVEXIN] is in clinical development for the treatment of various cancers. The p53 tumour suppressor gene is deleted or mutated in many tumour cells and is one of the most frequently mutated genes in human tumours. INGN 201 has been shown to kill cancer cells directly. In August 2002, Introgen announced plans to file an application for INGN 201 with the European Agency for the Evaluation of Medicinal Products (EMEA) for the treatment of head and neck cancer; the European filing will be submitted simultaneously with the previously scheduled (planned for 2004) submission of a Biologics License Application (BLA) for ADVEXIN to the US FDA. On 20 February 2003, INGN 201 received orphan drug designation from the US FDA for head and neck cancer. INGN 201 is available for licensing although Introgen favours retaining partial or full rights to the therapy in the US. Introgen Therapeutics and its collaborative partner for the p53 programme, Aventis Gencell, have been developing p53 gene therapy products. The agreement was originally signed by Rhône-Poulenc Rorer's Gencell division, which became Aventis Gencell after Rhône-Poulenc Rorer merged with Hoechst Marion Roussel to form Aventis Pharma. According to the original agreement, Introgen was responsible for phase I and preclinical development in North America, while Aventis Gencell was responsible for clinical trials conducted in Europe and for clinical trials in North America beyond phase I. In April 2001, Aventis Gencell and Introgen restructured their existing collaboration agreement for p53 gene therapy products. Aventis Gencell indicated that p53 research had suffered from internal competition for resources and was pulling back from its development agreement with Introgen for p53 gene therapy products. Introgen will assume responsibility for worldwide development of all p53 programmes and will obtain exclusive worldwide commercial rights to p53-based gene therapy

    Enzymatically modified soy proteins have the amino acid profile and functional properties required for dietary support. The objective of this study was to evaluate the nutritional and technological properties of an enzymatically modified soy protein ultrafiltered fraction with bound methionine (F(1-10)E) to be used as a protein ingredient for infant enteral formulas. F(1-10)E was chemically characterized and biologically evaluated. Thirty-six weaning Wistar rats were fed during 3 weeks with a 4% casein-containing diet. Rats were divided into three groups and recovered for 3 weeks with 18% protein-containing diets based on: (1) F(1-10)E, (2) casein or (3) soy isolate+methionine. Nutritional indicators were weight gain, protein efficiency ratio, plasma proteins, apparent digestibility and protein in the carcass. Additionally, F(1-10)E was added as a protein ingredient of an enteral formula, and its sensory and rheological properties were compared with a hydrolyzed-whey protein commercial formula. F(1-10)E contained 68% protein and 5% sulphur amino acids, with 60% of peptides 0.05) in weight gain (108 g and 118 g, respectively), protein efficiency ratio (2.7), apparent digestibility (93% and 95%), plasma proteins (5.7 mg/100 ml) and carcass protein (61%), and better than soy isolate-based+methionine diet (Pformula and our formula was similar during a 24-h period.

    In this article, it is postulated that the development of a successful training program for women in science, math, engineering, and technology (SMET) disciplines is dependent upon a combination of several factors, including (a) career orientation: commitment to SMET as a career, reasons for pursuing SMET as a career, and opportunity to pursue a SMET career; (b) knowledge of SMET: SMET courses completed, SMET achievement, and hands-on SMET activities; (c) academic and social support: diversity initiatives, role models, cooperative learning, and peer counseling; and (d) self-concept: program emphasis on competence and peer competition. The proposed model is based on the GET SMART (Girls Entering Technology, Science, Math and Research Training) workshop program to prepare and develop female high school students as competitive future SMET professionals. The proposed model is not intended to serve as an elaborate theory, but as a general guide in training females entering SMET disciplines.

    Achieving adoption, use, and integration of information and communication technology by healthcare clinicians in the workplace is recognized as a challenge that requires a multifaceted approach. This article explores community health nurses' engagement with information and communication technology as part of a larger research project that investigated the delivery of self-management support to people with chronic obstructive pulmonary disease. Following a survey of computer skills, participants were provided with computer training to support use of the project information system. Changes in practice were explored using action research meetings and individual semistructured interviews. Results highlight three domains that affected nurses' acceptance, utilization, and integration of information and communication technology into practice; environmental issues; factors in building capacity, confidence, and trust in the technology; and developing competence. Nurses face individual and practice challenges when attempting to integrate new processes into work activities, and the use of participatory models to support adoption is recommended.

    Full Text Available In the absence of immortality, the human species has over the millennia developed rites and rituals to help in the passing of life to honor the person who is dying or has died or in some way demonstrate their “courage” and perseverance as well as duty even in the face of almost certain death. The centuries-old traditions of the gathering of loved ones, the chanting of prayers, the ritual religious blessings are in the process of being replaced by the “miracles” of modern medical technology.

    A large scale program to develop a conceptual design for a demonstration fusion power plant (DEMO) has been initiated in Europe. Central elements are the baseline design points, which are developed by system codes. The assessment of the credibility of these design points is often hampered by missing information. The main physics and technology content of the central European system codes have been published (Kovari et al 2014 Fusion Eng. Des. 89 3054-69, 2016 Fusion Eng. Des. 104 9-20, Reux et al 2015 Nucl. Fusion 55 073011). In addition, this publication discusses key input parameters for the pulsed and conservative design option \\tt{EU DEMO1 2015} and provides justifications for the parameter choices. In this context several DEMO physics gaps are identified, which need to be addressed in the future to reduce the uncertainty in predicting the performance of the device. Also the sensitivities of net electric power and pulse duration to variations of the input parameters are investigated. The most extreme sensitivity is found for the elongation ( Δ {κ95}=10 % corresponds to Δ {{P}\\text{el,\\text{net}}}=125 % ).

  13. Supporting Students with Disabilities Entering the Science, Technology, Engineering, and Mathematics Field Disciplines

    Dishauzi, Karen M.

    Extensive research exists on female, African American, and Hispanic students pursuing Science, Technology, Engineering and Mathematics (STEM) field disciplines. However, little research evaluates students with disabilities and career decision-making relating to STEM field disciplines. This study explored the career decision-making experiences and self-efficacy for students with disabilities. The purpose of this research study was to document experiences and perceptions of students with disabilities who pursue, and may consider pursuing, careers in the STEM field disciplines by exploring the career decision-making self-efficacy of students with disabilities. This study documented the level of influence that the students with disabilities had or may not have had encountered from parents, friends, advisors, counselors, and instructors as they managed their decision-making choice relating to their academic major/career in the STEM or non-STEM field disciplines. A total of 85 respondents of approximately 340 students with disabilities at one Midwestern public university completed a quantitatively designed survey instrument. The Career Decision-Making Self-Efficacy Scale-Short Form by Betz and Hackett was the instrument used, and additional questions were included in the survey. Data analysis included descriptive statistics and analysis of variance. Based upon the results, college students with disabilities are not currently being influenced by individuals and groups of individuals to pursue the STEM field disciplines. This is a cohort of individuals who can be marketed to increase enrollment in STEM programs at academic institutions. This research further found that gender differences at the institution under study did not affect the career decision-making self-efficacy scores. The men did not score any higher in confidence in career decision-making than the women. Disability type did not significantly affect the relationship between the Career Decision-Making Self

    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.

  20. Pediatric enteral nutrition.

    Axelrod, David; Kazmerski, Kimberly; Iyer, Kishore

    2006-01-01

    Common to all pediatric patients receiving enteral nutrition is the inability to consume calories orally. This is often secondary to issues of inadequate weight gain, inadequate growth, prolonged feeding times, weight loss, a decrease in weight/age or weight/height ratios, or a persistent triceps skinfold thickness <5% for age. Enteral nutrition requires enteral access. In the neonatal period the nasoenteric route is usually used. In pediatric patients requiring long-term enteral access, surgically, endoscopically, or radiologically placed percutaneous feeding tubes are common. Jejunal feeding tubes are used in pediatric patients with gastric feeding intolerance or persistent gastroesophageal reflux. Low-profile enteral access devices are preferred by most pediatric patients because of their cosmetic appearance. For most children, a standard pediatric polypeptide enteral formula is well tolerated. There are specialized pediatric enteral formulas available for patients with decreased intestinal length, altered intestinal absorptive capacity, or altered pancreatic function. Weaning patients from tube feeding to oral nutrition is the ultimate nutrition goal. A multidisciplinary approach to patients with short bowel syndrome will maximize the use of enteral nutrition while preserving parenteral nutrition for patients with true enteral nutrition therapy failure.

  1. Loop-mediated isothermal amplification as an emerging technology for detection of Yersinia ruckeri the causative agent of enteric red mouth disease in fish

    Directory of Open Access Journals (Sweden)

    2008-08-01

    Full Text Available Abstract Background Enteric Redmouth (ERM disease also known as Yersiniosis is a contagious disease affecting salmonids, mainly rainbow trout. The causative agent is the gram-negative bacterium Yersinia ruckeri. The disease can be diagnosed by isolation and identification of the causative agent, or detection of the Pathogen using fluorescent antibody tests, ELISA and PCR assays. These diagnostic methods are laborious, time consuming and need well trained personnel. Results A loop-mediated isothermal amplification (LAMP assay was developed and evaluated for detection of Y. ruckeri the etiological agent of enteric red mouth (ERM disease in salmonids. The assay was optimised to amplify the yruI/yruR gene, which encodes Y. ruckeri quorum sensing system, in the presence of a specific primer set and Bst DNA polymerase at an isothermal temperature of 63°C for one hour. Amplification products were detected by visual inspection, agarose gel electrophoresis and by real-time monitoring of turbidity resulted by formation of LAMP amplicons. Digestion with HphI restriction enzyme demonstrated that the amplified product was unique. The specificity of the assay was verified by the absence of amplification products when tested against related bacteria. The assay had 10-fold higher sensitivity compared with conventional PCR and successfully detected Y. ruckeri not only in pure bacterial culture but also in tissue homogenates of infected fish. Conclusion The ERM-LAMP assay represents a practical alternative to the microbiological approach for rapid, sensitive and specific detection of Y. ruckeri in fish farms. The assay is carried out in one hour and needs only a heating block or water bath as laboratory furniture. The advantages of the ERM-LAMP assay make it a promising tool for molecular detection of enteric red mouth disease in fish farms.

    Dietary fibre is a mixture of various substances and is essential for maintaining appropriate intestinal functionality and it is currently considered to be a necessary part of a healthy diet. Current recommendations for fibre consumption by adults range from 20 to 35 g/day. Enteral nutrition is an emerging therapeutic variation in both hospital and domestic settings. To a great extent, this development has been made possible thanks to the design of new formulas that adapt better and better to the clinicla conditions or our patients. The type of fibre used in these preparations varies greatly. Some have only one source of fibre while others use differnet combinations. There are currently 32 formulas available on the Spanish market, without counting the modules or specific preparations of individual types of fibre. Despite the enormous advances in the knowledge of the beneficial effects of fibre, the fact of the matter is that enteral nutrition that we routinely prescribe in normal clinical practice does not contain fibre. The are several explanations for this, perhaps the most plausible is that these formulas may lead to problems in their administration and tolerance. It is necessary to choose the correct calibre of catheter and define the best infusion method and timing. Another difficulty may be the gastrointestinal tolerance of the formulas containing fibre. No large-scale problems of intolerance have however been described in healthy volunteers nor in patients with acute or chronic pathologies, although it is of fundamental importance to monitor the rhythm of depositions in all patients with enteral nutrition (EN) and ensure proper intake of liquids, which would also be useful to prevent occlusion of the catheter. The theoretical benefits of EN with fibre with a view to maintaining or improving normal intestinal structure and function are very varied. Nonetheless, it has noit yet been possible to prove many of these effects in controlled clinical trials. At the

    There is growing evidence that we are now entering a new geological age defined by human influence on the planet, the Anthropocene. Millions of years from now, a stripe in the accumulated layers of rock on Earth's surface will reveal our human fingerprint just as we can see evidence of dinosaurs in rocks of the Jurassic, or the explosion of life that marks the Cambrian. There is now no part of the planet untouched by human influence. The realisation that we wield such planetary power requires a quite extraordinary shift in perception, fundamentally toppling the scientific, cultural and religious philosophies that define our place in the world. This session explores these issues and examines our new relationship with nature now that we so strongly influence the biosphere. And this session will look at what the impacts of our planetary changes mean for us, and how we might deal with the consequences of the Anthropocene we have created.

    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.

    Microscopic enteritis (ME) is an inflammatory condition of the small bowel that leads to gastrointestinal symptoms, nutrient and micronutrient deficiency. It is characterised by microscopic or sub-microscopic abnormalities such as microvillus changes and enterocytic alterations in the absence of definite macroscopic changes using standard modern endoscopy. This work recognises a need to characterize disorders with microscopic and submicroscopic features, currently regarded as functional or non-specific entities, to obtain further understanding of their clinical relevance. The consensus working party reviewed statements about the aetiology, diagnosis and symptoms associated with ME and proposes an algorithm for its investigation and treatment. Following the 5(th) International Course in Digestive Pathology in Bucharest in November 2012, an international group of 21 interested pathologists and gastroenterologists formed a working party with a view to formulating a consensus statement on ME. A five-step agreement scale (from strong agreement to strong disagreement) was used to score 21 statements, independently. There was strong agreement on all statements about ME histology (95%-100%). Statements concerning diagnosis achieved 85% to 100% agreement. A statement on the management of ME elicited agreement from the lowest rate (60%) up to 100%. The remaining two categories showed general agreement between experts on clinical presentation (75%-95%) and pathogenesis (80%-90%) of ME. There was strong agreement on the histological definition of ME. Weaker agreement on management indicates a need for further investigations, better definitions and clinical trials to produce quality guidelines for management. This ME consensus is a step toward greater recognition of a significant entity affecting symptomatic patients previously labelled as non-specific or functional enteropathy.

    OBJECTIVE: All forms of commonly practiced enteral feeding techniques stimulate pancreatic secretion, and only intravenous feeding avoids it. In this study, we explored the possibility of more distal enteral infusions of tube feeds to see whether activation of the ileal brake mechanism can result...... in enteral feeding without pancreatic stimulation, with particular reference to trypsin, because the avoidance of trypsin stimulation may optimize enteral feeding in acute pancreatitis. METHODS: The pancreatic secretory responses to feeding were studied in 36 healthy volunteers by standard double......-lumen duodenal perfusion/aspiration techniques over 6 hours. Subjects were assigned to no feeding (n = 7), duodenal feeding with a polymeric diet (n = 7) or low-fat elemental diet (n = 6), mid-distal jejunal feeding (n = 11), or intravenous feeding (n = 5). All diets provided 40 kcal/kg ideal body weight/d and 1...

    Enteral nutrition (EN) support has proven to be a nutrition intervention that can provide full or partial calories to promote growth and development in infants and children. To supply these nutrients, an enteral access device is required, and the use of these devices is growing. Placement of the proper device for the patient need, along with appropriate care and monitoring, is required for individualized patient management. When complications arise, early identification and management can prevent more serious morbidity. Complication management requires a tiered approach starting with staff nurses and ending with a physician expert. In addition to this, each institution needs to have an approach that is coordinated among disciplines and departments to promote consistency of practice. The formation of an enteral access team is a conduit for clinical experts to provide education to families, patients, and healthcare professionals while serving as a platform to address product and practice issues. © 2016 American Society for Parenteral and Enteral Nutrition.

    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

    2013-07-01

    Canine parvovirus (CPV) enteritis has, since its emergence in 1978, remained a common and important cause of morbidity and mortality in young dogs. The continued incidence of parvoviral enteritis is partly due to the virus' capability to evolve into more virulent and resistant variants with significant local gastrointestinal and systemic inflammatory sequelae. This paper reviews current knowledge on historical-, signalment-, and clinical factors as well as several haematological-, biochemical- and endocrine parameters that can be used as diagnostic and prognostic biomarkers in CPV enteritis. These factors include season of presentation, purebred nature, bodyweight, vomiting, leukopaenia, lymphopaenia, thrombocytopaenia, hypercoagulability, hypercortisolaemia, hypothyroxinaemia, hypoalbuminaemia, elevated C-reactive protein and tumour necrosis factor, hypocholesterolaemia and hypocitrullinaemia. Factors contributing to the manifestations of CPV infection are multiple with elements of host, pathogen, secondary infections, underlying stressors and environment affecting severity and outcome. The availability of several prognosticators has made identification of patients at high risk of death and their subsequent targeted management more rewarding.

    A 76-year-old man had small bowel obstruction and organic small bowel disease following a series of bizarre massive gustatory insults that involved food, medications, and mega-mineral-vitamin supplements. Intestinal obstruction required partial small bowel resection. The dietary indiscretions resulted in severe enteritis (indiscretion enteritis). The sequence has been termed a Rabelaisian syndrome after the great French writer and physician, Francois Rabelais, who vividly described bizarre gustatory habits. Gut injury may result from unwise oral intake of various foods and mineral supplements.

    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

    Radiation enteritis is defined as the loss of absorptive capacity of the intestine following irradiation, which is most commonly seen after radiotherapy for pelvic and abdominal malignancies. It is divided into acute and chronic forms and usually presents with diarrhea and malabsorption. Malnutrition is a common complication of chronic radiation enteritis (CRE). We reviewed the etiology, prevalence, symptoms, diagnosis and management of CRE and CRE with malnutrition in this article. Functional short bowel syndrome as a cause of malnutrition in CRE is also considered. The diagnostic work-up includes serum markers, endoscopy, cross-sectional imaging and the exclusion of alternative diagnoses such as recurrent malignancy. Management options of CRE include dietary manipulation, anti-motility agents, electrolyte correction, probiotics, parenteral nutrition, surgical resection and small bowel transplantation. Treatment may also be required for coexisting conditions including vitamin B12 deficiency, bile acid malabsorption and depression.

    The extracellular secreted mucus and the cell surface glycocalyx prevent infection by the vast numbers of microorganisms that live in the healthy gut. Mucin glycoproteins are the major component of these barriers. In this Review, we describe the components of the secreted and cell surface mucosal barriers and the evidence that they form an effective barricade against potential pathogens. However, successful enteric pathogens have evolved strategies to circumvent these barriers. We discuss the interactions between enteric pathogens and mucins, and the mechanisms that these pathogens use to disrupt and avoid mucosal barriers. In addition, we describe dynamic alterations in the mucin barrier that are driven by host innate and adaptive immune responses to infection.

    1. Medical and surgical stress (major surgery, sepsis, injuries,...) increases requirements of certain essential nutrients and others considered non-essential or semi-essential. 2. Some nutrients such as glutamine, arginine, omega 3 fatty acids nucleotides, ... have a considerable influence on the immune function (delayed hypersensitivity, lymphocyte sub-population counts, immunological tests,..) and improve certain metabolic and nutritional indices (nitrogen balance, medium and short life proteins,...). For this reason, they are called "immunonutrients" or "immunity regulators". 3. The supply of special enteral formulas for situations of immunological compromise, with the addition of one or more of the nutrients considered today as "immunity regulators" has increased since 1988 in both absolute and percentage terms. 4. These nutrient-enriched enteral formulas improve the rate of infections, reduce the number of days on ventilator equipment, the length of hospital stays for critical patients, with a more marked effect on surgical patients. 5. The evidence seems today to support the use of enriched formulas with critical patients. Nonetheless, some caution must be maintained as it has not been possible to show any reduction in the mortality of the cases studied nor, in short, in the prognosis of patients affected by situations of hypercatabolism and reduced immunity. 6. We feel that their use should, therefore, be carried out in accordance with the protocols and in patients expected to survive, where the evolution reveals severe catabolism unhindered by conventional therapy.

    Diarrheal diseases are a major cause of childhood death in resource-poor countries, killing approximately 760,000 children younger than 5 years each year. Although deaths due to diarrhea have declined dramatically, high rates of stunting and malnutrition have persisted. Environmental enteric dysfunction (EED) is a subclinical condition caused by constant fecal-oral contamination with resultant intestinal inflammation and villous blunting. These histological changes were first described in the 1960s, but the clinical effect of EED is only just being recognized in the context of failure of nutritional interventions and oral vaccines in resource-poor countries. We review the existing literature regarding the underlying causes of and potential interventions for EED in children, highlighting the epidemiology, clinical and histologic classification of the entity, and discussing novel biomarkers and possible therapies. Future research priorities are also discussed.

    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 < .0001). All 3 EFS handling techniques displayed low bacterial growth. RTH was superior in bacterial growth, nursing time, and supply costs. Since not all pediatric formulas are available in RTH, we conclude that refrigerating the EFS between uses is the next most efficacious method for handling the EFS between bolus feeds.

    Aortic graft fistula is a rare and life-threatening complication after aortic reconstruction. The incidence ranges from 0.5 to 4%, and even if the diagnosis and treatment is appropriate, the results of surgery are poor: mortality rate ranges from 14 to 70%. The optimal method of treatment is still controversial; prosthetic removal and extra-anatomic bypass has been advocated as the standard method, but more recently, because the high mortality rate associated with this procedure, some have prompted to recommend in situ aortic graft replacement as a more successful treatment. Personal experience with incidence (0.7%) outcome and mortality (57%) in 7 patients treated over a period of 6 years (1990-1996) is reported. Results from this group are compared with another group (6 patients) previously treated (1975-1982) for the same pathology. Our results after 10 years, show the same incidence (0.7 vs 0.6%) and an elevated and unchanged mortality (57 vs 66%). Better results in the management of aorto-enteric fistulas could be achieved with the removal of infected infrarenal aortic prosthetic grafts and in situ homografts replacement.

    Santamaría, Johanna; Toranzos, Gary A

    2003-03-01

    It is known that soil is a recipient of solid wastes able to contain enteric pathogens in high concentrations. Although the role of soil as a reservoir of certain bacterial pathogens is not in question, recent findings show that soil may have a larger role in the transmission of enteric diseases than previously thought. Many of the diseases caused by agents from soil have been well characterized, although enteric diseases and their link to soil have not been so well studied. Gastrointestinal infections are the most common diseases caused by enteric bacteria. Some examples are salmonellosis ( Salmonella sp.), cholera ( Vibrio cholerae), dysentery ( Shigella sp.) and other infections caused by Campylobacter jejuni, Yersinia sp. and Escherichia coli O157:H7 and many other strains. Viruses are the most hazardous and have some of the lowest infectious doses of any of the enteric pathogens. Hepatitis A, hepatitis E, enteric adenoviruses, poliovirus types 1 and 2, multiple strains of echoviruses and coxsackievirus are enteric viruses associated with human wastewater. Among the most commonly detected protozoa in sewage are Entamoeba histolytica, Giardia intestinalis and Cryptosporidium parvum.

    The technology is available to produce fuel ethanol from renewable lignocellulosic biomass. The current challenge is to assemble the various process options into a commercial venture and begin the task of incremental improvement. Current process designs for lignocellulose are far more complex than grain to ethanol processes. This complexity results in part from the complexity of the substrate and the biological limitations of the catalyst. Their work at the University of Florida has focused primarily on the genetic engineering of Enteric bacteria using genes encoding Zymomonas mobilis pyruvate decarboxylase and alcohol dehydrogenase. These two genes have been assembled into a portable ethanol production cassette, the PET operon, and integrated into the chromosome of Escherichia coli B for use with hemicellulose-derived syrups. The resulting strain, KO11, produces ethanol efficiently from all hexose and pentose sugars present in the polymers of hemicellulose. By using the same approach, the authors integrated the PET operon into the chromosome of Klebsiella oxytoca to produce strain P2 for use in the simultaneous saccharification and fermentation (SSF) process for cellulose. Strain P2 has the native ability to ferment cellobiose and cellotriose, eliminating the need for one class of cellulase enzymes.

    During the last twenty five years there have been major changes in the HVAC equipment offered in the marketplace. One of the product lines with the most significant changes is that of centrifugal chillers. It has been impacted by two strong forces: (1) the need for energy efficiency, and (2) regulations against the use of CFC refrigerants. Chiller manufacturers reacted in impressive fashion, furnishing non-CFC chillers with increased efficiency achieved through a variety of technology improvements. These gains continue, under the influence of ongoing market needs and changes. (orig.)

  6. Measurement and prediction of enteric methane emission

    2011-01-01

    The greenhouse gas (GHG) emissions from the agricultural sector account for about 25.5% of total global anthropogenic emission. While CO2 receives the most attention as a factor relative to global warming, CH4, N2O and chlorofluorocarbons (CFCs) also cause significant radiative forcing. With the relative global warming potential of 25 compared with CO2, CH4 is one of the most important GHGs. This article reviews the prediction models, estimation methodology and strategies for reducing enteric CH4 emissions. Emission of CH4 in ruminants differs among developed and developing countries, depending on factors like animal species, breed, pH of rumen fluid, ratio of acetate:propionate, methanogen population, composition of diet and amount of concentrate fed. Among the ruminant animals, cattle contribute the most towards the greenhouse effect through methane emission followed by sheep, goats and buffalos, respectively. The estimated CH4 emission rate per cattle, buffaloe, sheep and goat in developed countries are 150.7, 137, 21.9 and 13.7 (g/animal/day) respectively. However, the estimated rates in developing countries are significantly lower at 95.9 and 13.7 (g/animal/day) per cattle and sheep, respectively. There exists a strong interest in developing new and improving the existing CH4 prediction models to identify mitigation strategies for reducing the overall CH4 emissions. A synthesis of the available literature suggests that the mechanistic models are superior to empirical models in accurately predicting the CH4 emission from dairy farms. The latest development in prediction model is the integrated farm system model which is a process-based whole-farm simulation technique. Several techniques are used to quantify enteric CH4 emissions starting from whole animal chambers to sulfur hexafluoride (SF6) tracer techniques. The latest technology developed to estimate CH4 more accurately is the micrometeorological mass difference technique. Because the conditions under which

    2013-12-01

    Water quality through the presence of pathogenic enteric microorganisms may affect human health. Coliform bacteria, Escherichia coli and coliphages are normally used as indicators of water quality. However, the presence of above-mentioned indicators do not always suggest the presence of human enteric viruses. It is important to study human enteric viruses in water. Human enteric viruses can tolerate fluctuating environmental conditions and survive in the environment for long periods of time becoming causal agents of diarrhoeal diseases. Therefore, the potential of human pathogenic viruses as significant indicators of water quality is emerging. Human Adenoviruses and other viruses have been proposed as suitable indices for the effective identification of such organisms of human origin contaminating water systems. This article reports on the recent developments in the management of water quality specifically focusing on human enteric viruses as indicators.

    Enteric neuropathy is a term indicating an impairment of the innervation supplying the gastrointestinal tract. The clinical phenotypes of the enteric neuropathies are the 'tip of the iceberg' of severe functional digestive diseases, such as intestinal pseudo-obstruction syndromes (e.g., chronic intestinal pseudo-obstruction). Despite progress acquired over the years, the pathogenetic mechanisms leading to enteric neuropathies are still far from being elucidated and the therapeutic approaches to these patients are mainly supportive, rather than curative.The purpose of this chapter is to review the advancements that have been done in the knowledge of enteric neuropathies identified in adult patients ('tomorrow'), going through where we currently are ('today') following a brief history of the major milestones on the pioneering discoveries in the field ('yesterday').

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.

    Hydrogen peroxide is a useful disinfectant that has achieved widespread utility in varied clinical settings. We report an epidemic of hydrogen peroxide enteritis that developed in seven patients in our gastrointestinal endoscopy unit during a 2-week period in early 1988. During endoscopy, using recently sterilized endoscopes that were flushed with 3% hydrogen peroxide after the glutaraldehyde cycle, instantaneous blanching (the "snow white" sign) and effervescence were noted on the mucosal surfaces when the water button was depressed. No patient subsequently suffered morbidity or mortality associated with this peroxide enteritis, and the biopsy specimens revealed nonspecific inflammation. The toxicity of hydrogen peroxide when used in enema form is reviewed, as well as the pathogenesis of peroxide enteritis.

    The gastrointestinal system of horses is affected by a large variety of inflammatory infectious and noninfectious conditions. The most prevalent form of gastritis is associated with ulceration of the pars esophagea. Although the diagnostic techniques for alimentary diseases of horses have improved significantly over the past few years, difficulties still exist in establishing the causes of a significant number of enteric diseases in this species. This problem is compounded by several agents of enteric disease also being found in the intestine of clinically normal horses, which questions the validity of the mere detection of these agents in the intestine.

    Hendricks, C W

    1972-08-01

    Enteric bacteria, including stocked strains of pathogenic species and organisms naturally present in the stream, were capable of growth in a chemostat with autoclaved river water taken 750 m below a sewage outfall. Maximal specific growth rates for all organisms occurred at 30 C, whereas culture generation times ranged between 33.3 and 116 hr. Of the six laboratory strains of enteric species used, Escherichia coli and Enterobacter aerogenes grew at generation times of 34.5 and 33.3 hr, respectively, while the remaining Proteus, Arizona, Salmonella, and Shigella spp. reproduced at a rate two to three times slower than the coliforms. Little or no growth occurred in the water at incubation temperatures of 20 and 5 C, and death was observed for Salmonella senftenberg at 20 and 5 C and for E. aerogenes and Proteus rettgeri at 5 C. When enteric bacteria naturally present in the river water were employed in similar experiments, coliform bacteria demonstrated a generation time of approximately 116 hr, whereas fecal coliforms failed to grow. Growth of the bacteria from the river demonstrated a periodicity of approximately 100 hr, which suggests that much of the growth of these organisms in the chemostat may be on the glass surfaces. This phenomenon, however, was not observed with any of the stocked enteric species. Neither the stock cultures nor the aquatic strains were capable of growth in autoclaved river water taken above the sewage outfall at the three temperatures tested.

    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.

Bacteriol. 87:1389-1396. 1964.-When Saccharomyces carlsbergensis (two strains) and S. cerevisiae (one strain) were grown in static culture and the harvested, washed cells were suspended in a solution of glucose, amino acids were suddenly released and then rapidly reabsorbed in a space of about 2 hr. The phenomenon of amino acid release, which was termed shock excretion, varied in intensity with the strain of yeast and was shown to be dependent on the size of the pool of free amino acids within the cells. Shock excretion was independent of osmotic pressure of the suspending medium, but required the presence of a fermentable sugar. d-Galactose and maltose caused shock excretion only when yeast was previously adapted to these sugars. Limiting glucose concentrations prevented reabsorption of amino acids, and a further decrease in glucose concentration also limited excretion. Shock excretion was strikingly reduced when the temperature of the suspending medium was lowered.

    1992-01-01

    The hypermetabolism that develops in patients with severe polytraumatism has led to the need for an aggressive metabolic-nutritional support from the start. Parenteral Nutrition is the preferred technique in many instances, due to the doubts on the effectiveness of enteral nutrition in the control of the metabolic response and to problems of gastrointestinal tolerance derived from its administration. However, the role of enteral nutrition as an important factor which limits the development of bacterial translocation and the chain of events leading to multiorganic failure appears to be more and more well-established and is an important argument for justifying the early administration of enteral nutrition in these patients. In accordance with the accumulated experience of several authors over the past few years, enteral nutrition may be administered early in polytraumatized patients. This is not only accompanied by the evidence of acceptable gastrointestinal tolerance to the diet, but also by additional advantages compared to parenteral nutrition, such as the maintenance of trophism and immunocompetence of the digestive mucosa, the reduction of septic complications and also greater nutritional effectiveness which can be evaluated by the behaviour of the seric proteins used as nutritional evolution markers. The interest of the different diet formulae which exist at present, for example diets enriched with branched-chain amino acids, diets with added fibre, peptidic diets, specific pulmonary diets or "euglycaemic diets" is evaluated in this review. All these diets may mean an increase in the effectiveness and/or tolerance of enteral nutrition in polytraumatized patients, and also contribute to the handling of specific problems such as "stress" hyperglycaemia or the withdrawal of mechanical ventilation support. The use of specific nutrients for the digestive mucosa, such as glutamine or short chain fatty acids seems to be an important factor in the reduction of

    Beer, W.H.; Fan, A.; Halsted, C.H.

    1985-01-01

    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.

  3. Enteral nutrition of the premature infant

    Full Text Available Early nutritional support for preterm infants is critical because such support influences long-term outcome. Minimal enteral feeding should be initiated as soon as possible if an infant is stable and if feeding advancement is recommended as relevant to the clinical course. Maternal milk is the gold standard for enteral feeding, but fortification may be needed to achieve optimal growth in a rapidly growing premature infant. Erythromycin may aid in promoting gastrointestinal motility in cases that exhibit feeding intolerance. Selected preterm infants need vitamins, mineral supplements, and calorie enhancers to meet their nutritional needs. Despite all that is known about this topic, additional research is needed to guide postdischarge nutrition of preterm infants in order to maintain optimal growth and neurodevelopment.

    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.

    Human immune deficient virus (HIV) is an immunosuppressive virus that targets CD4(+) T-lymphocytes. HIV infections cause increased susceptibility to opportunistic infections and cancer. HIV infection can also alter central nervous system (CNS) function causing cognitive impairment. HIV does not infect neurons but it does infect astrocytes and microglia in the CNS. HIV can also infect enteric glia initiating an intestinal inflammatory response which causes enteric neural injury and gut dysfunction. Part of the inflammatory response is HIV induced production of proteins including, Transactivator of transcription (Tat) which contribute to neuronal injury after release from HIV infected glial cells. A risk factor for HIV infection is intravenous drug use with contaminated needles and chronic opiate use can exacerbate neural injury in the nervous system. While most research focuses on the actions of Tat and other HIV related proteins and opiates on the brain, recent data indicate that Tat can cause intestinal inflammation and disruption of enteric neuron function, including alteration of Na(+) channel activity and action potential generation. A paper published in this issue of Neurogastroenterology and Motility extends these findings by identifying an interaction between Tat and morphine on enteric neuron Na(+) channels and on intestinal motility in vivo using a Tat expressing transgenic mouse model. These new data show that Tat protein can enhance the inhibitory actions of morphine on action potential generation and propulsive motility. These findings are important to our understanding of how HIV causes diarrhea in infected patients and for the use of opioid drugs to treat HIV-induced diarrhea.

    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.

    2017-06-01

    Neurointestinal diseases are increasingly recognized as causes of significant gastrointestinal morbidity in children. This review highlights the most common pediatric enteric neuropathies and their diagnosis and management, emphasizing insights and discoveries from the most recent literature available. The embryologic and histopathologic causes of enteric neuropathies are varied. They range from congenital aganglionosis in Hirschsprung disease, to autoimmune-mediated loss of neuronal subtypes in esophageal achalasia and Chagas disease, to degenerative neuropathies in some cases of chronic intestinal pseudo-obstruction and gastroparesis. Increased awareness of the clinical presentation and diagnostic evaluation of these conditions is essential as it allows for earlier initiation of treatment and improved outcomes. Most current therapies, which include medical management, neurostimulation, and operative intervention, aim to minimize the symptoms caused by these conditions. The evidence base for many of these treatments in children is poor, and multiinstitutional prospective studies are needed. An innovative therapy on the horizon involves using neuronal stem cell transplantation to treat the underlying disorder by replacing the missing or damaged neurons in these diseases. Although recent advances in basic and clinical neurogastroenterology have significantly improved our awareness and understanding of enteric neuropathies, the efficacy of current treatment approaches is limited. The development of novel therapies, including pharmacologic modulators of neurointestinal function, neurostimulation to enhance gut motility, and neuronal cell-based therapies, is essential to improve the long-term outcomes in children with these disorders.

    2003-10-02

    The influence of subcoat application and micro-environmental pH on the dissolution properties of enteric coated sodium valproate pellets was investigated. The pellets were prepared by solution-layering or wet-mass extrusion-spheronization methods. In order to pass the USP enteric test, the solution-layered and wet-mass extruded pellets required 35 and 25% weight gain of Eudragit L 30D-55, respectively. The application of a subcoat of either Methocel-E5 (HPMC) or Opadry AMB to the pellets resulted in a delay in sodium valproate release in 0.1N HCl. Further delay in drug release was observed when citric acid was present in a HPMC subcoat or when added to the core pellet formulation. The amount of drug released from coated pellets was a function of the level of citric acid in the pellet core or subcoat and subsequent micro-environmental pH of the pellets. Citric acid exerted a plasticizing effect on the enteric polymer film and improved film formation and polymer coalescence. When greater than 10% (w/w) citric acid was present in the pellets, a decrease in drug content was observed due to the conversion of sodium valproate to the volatile compound, valproic acid. Pellets containing less than 10% (w/w) citric acid maintained potency during processing.

    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.

    2014-09-01

    Full Text Available In this review, diagnostic techniques and viral agents involved in enteric diseases affecting turkeys are described. Data from field observations and laboratory researches have been reported in turkey flocks for over 70 years, and several viruses have been identified. After a period of 30 years of inoculation experiments and neutralization studies, adequate visualization of the viruses was achieved using electronic microscopy. During the following years, several studies were then conducted to isolate and classify those viruses using cell-culture, embryo-propagation, serological tests, genome electropherotyping by polyacrylamide gel electrophoresis of double-stranded RNA viruses, and recently, nucleic acid studies. Thus, since the 1990s, the nucleic-acid technology has focused on genomic surveys and on the detection of specific segments of the genome of each virus using the polymerase-chain reaction, resulting in several prevalence studies and phylogenetic analyses of different isolates and proper classification of the viruses.

    2009-10-01

    Full Text Available Abstract Background Pregnancies complicated by abnormal umbilical artery Doppler blood flow patterns often result in the baby being born both preterm and growth-restricted. These babies are at high risk of milk intolerance and necrotising enterocolitis, as well as post-natal growth failure, and there is no clinical consensus about how best to feed them. Policies of both early milk feeding and late milk feeding are widely used. This randomised controlled trial aims to determine whether a policy of early initiation of milk feeds is beneficial compared with late initiation. Optimising neonatal feeding for this group of babies may have long-term health implications and if either of these policies is shown to be beneficial it can be immediately adopted into clinical practice. Methods and Design Babies with gestational age below 35 weeks, and with birth weight below 10th centile for gestational age, will be randomly allocated to an "early" or "late" enteral feeding regimen, commencing milk feeds on day 2 and day 6 after birth, respectively. Feeds will be gradually increased over 9-13 days (depending on gestational age using a schedule derived from those used in hospitals in the Eastern and South Western Regions of England, based on surveys of feeding practice. Primary outcome measures are time to establish full enteral feeding and necrotising enterocolitis; secondary outcomes include sepsis and growth. The target sample size is 400 babies. This sample size is large enough to detect a clinically meaningful difference of 3 days in time to establish full enteral feeds between the two feeding policies, with 90% power and a 5% 2-sided significance level. Initial recruitment period was 24 months, subsequently extended to 38 months. Discussion There is limited evidence from randomised controlled trials on which to base decisions regarding feeding policy in high risk preterm infants. This multicentre trial will help to guide clinical practice and may also

    Agriculture has a key role in food production worldwide and it is a major component of the gross domestic product of several countries. Livestock production is essential for the generation of high quality protein foods and the delivery of foods in regions where animal products are the main food source. Environmental impacts of livestock production have been examined for decades, but recently emission of methane from enteric fermentation has been targeted as a substantial greenhouse gas source. The quantification of methane emissions from livestock on a global scale relies on prediction models because measurements require specialized equipment and may be expensive. The predictive ability of current methane emission models remains poor. Moreover, the availability of information on livestock production systems has increased substantially over the years enabling the development of more detailed methane prediction models. In this study, we have developed and evaluated prediction models based on a large database of enteric methane emissions from North American dairy and beef cattle. Most probable models of various complexity levels were identified using a Bayesian model selection procedure and were fitted under a hierarchical setting. Energy intake, dietary fiber and lipid proportions, animal body weight and milk fat proportion were identified as key explanatory variables for predicting emissions. Models here developed substantially outperformed models currently used in national greenhouse gas inventories. Additionally, estimates of repeatability of methane emissions were lower than the ones from the literature and multicollinearity diagnostics suggested that prediction models are stable. In this context, we propose various enteric methane prediction models which require different levels of information availability and can be readily implemented in national greenhouse gas inventories of different complexity levels. The utilization of such models may reduce errors

    Enteral feedings are safely tolerated by most patients. When complications occur, gastrointestinal disturbances are most frequently encountered, followed by mechanical and metabolic complications. Nurses can prevent many of the problems associated with enteral feeding through careful monitoring. Based on the current literature, the authors make the following recommendations: 1. All patients receiving tube feedings should be placed on a protocol that provides guidelines for (a) confirming correct tube placement; (b) preventing/managing tube obstruction; (c) handling and selecting formulas; (d) administering formulas; and (e) monitoring patients. 2. Fine-bore tubes are easily misplaced or dislodged; ensure correct positioning both before and during feeding. Food coloring should be added to all feedings to help detect aspiration/tube displacement. 3. Multiple factors can cause diarrhea in tube-fed patients and, therefore, require periodic assessment. These factors include concomitant drug therapy; malnutrition/hypoalbuminemia; formula-related factors (for example, lactose content, osmolality); and bacterial contamination. 4. Urine sugar and acetone levels should be checked every 6 hours (until stable). Vital signs and fluid intake and output should be determined every 8 hours, and weight should be measured on a daily basis. Serum electrolytes, blood urea nitrogen, and glucose levels should be determined daily, until serum levels stabilize. Weekly measurements of trace elements should be made to ensure adequate mineral replacement. 5. Use a controller pump to administer continuous feedings at a constant rate or to administer formulas that are viscous. Flush feeding tubes with water every 4 hours during continuous feedings, after giving intermittent feedings, after giving medications, and after checking for gastric residuals. If tube obstruction occurs, attempt to irrigate the tube with either water or cola. 6. Select feedings that contain appropriate nutrient sources

    Infections of the gastrointestinal tract still are numerous, ranging on the second place after infections of the respiratory tract. Some of them show quite severe or prolonged course. In contrast to other infections, especially those of the urinary tract, laboratory diagnostic of enteritis is only scarcely ordered. During the last ten years new methods and knowledge of etiologic germs like Campylobacter, Yersinia, various types of E. coli, Clostridium difficile, Rotavirus, Adenovirus, Giardia, Blastomyces and Cryptosporidia have been accumulated. A better etiologic diagnosis of these infections should enable the clinician to start a more precise and therefore more effective therapy.

    Full Text Available Since about the 1950s nerves in the wall of the intestine have been postulated to play a role in the pathogenesis of inflammatory bowel disease (IBD. Human and animal studies examining the role of nerves in intestinal inflammation are the focus of this review. Consideration is given to two possible ways that nerves are involved in IBD. First, nerves may play a role in the development or maintenance of inflammation through local release of transmitters. Second, once initiated (by whatever means, the processes of inflammation may disrupt the normal pattern of innervation and the interactions of nerves and their target tissues. Many of the functional disturbances observed in IBD are likely due to an alteration in the enteric nervous system either structurally through disruptions of nerve-target relationships or by modifications of neurotransmitters or their receptors. Finally, it appears that the enteric nervous system may be a potential therapeutic target in IBD and that neuroactive drugs acting locally can represent useful agents in the management of this disease.

    Twenty-two flocks of turkeys affected by enteric problems, with ages between 10 and 104 days and located in the Southern region of Brazil, were surveyed for turkey by PCR for turkey astrovirus type 2 (TAstV-2), turkey coronavirus (TCoV), hemorrhagic enteritis virus (HEV), rotavirus, reovirus, Salmonella spp., and Lawsonia intracellularis (Li) infections. Eleven profiles of pathogen combination were observed. The most frequently encountered pathogen combinations were TCoV-Li, followed by TCoV-TAstV-2-Li, TCoV-TastV-2. Only TCoV was detected as the sole pathogen in three flocks. Eight and 19 flocks of the 22 were positive for TAstV-2 and TCoV, respectively. Six were positive for Salmonella spp. and L. intracellularis was detected in 12 turkey flocks. Reovirus and HEV were not detected in this survey. These results throw new light on the multiple etiology of enteritis in turkeys. The implications of these findings and their correlation with the clinical signs are comprehensively discussed, illustrating the complexity of the enteric diseases.

    Full Text Available Infections with Salmonella serotypes are a major cause of food-borne diseases worldwide. Animal models other than the mouse have been employed for the study of nontyphoidal Salmonella infections because the murine model is not suitable for the study of Salmonella-induced diarrhea. The microbe has developed mechanisms to exploit the host cell machinery to its own purpose. Bacterial proteins delivered directly into the host cell cytosol cause cytoskeletal changes and interfere with host cell signaling pathways, which ultimately enhance disease manifestation. Recently, marked advances have been made in our understanding of the molecular interactions between Salmonella serotypes and their hosts. Here, we discuss the molecular basis of the pathogenesis of Salmonella-induced enteritis.

Subjects and methods. Forty-three patients with different causes of inadequate GIT function of various origin and ACS (disseminated peritonitis (45%, pancreatitis (24%, and severe concomitant injury (31% were examined. Group 1 (control received complete parenteral nutritional feeding (n=23; APACHE II scores, 21±4; calculated probability of fatal outcome, 33.5%. In Group II (study, complete parenteral feeding in the first 24 hours after stabilization was supplemented with GIT function support with Pepsisorb (Nutricia in doses of 500, 1000, and 1500 ml on days 1, 2, and 3, respectively (n=20; APACHE II scores, 20±6; calculated probability of fatal outcome, 37.1%. During early enteral nutritional support, the SOFA score was significantly less than that in Group 1 on days 2—3; the oxygenation index significantly increased on day 3; the value of intra-abdominal hypertension decreased to the control values. The positive effect of the GIT function support regimen on regression of the multiple organ dysfunction syndrome (MODS was confirmed by the lowered levels of biological markers (von Willebrand factor (WF and endothelin-1 as markers of endothelial damage of MODS. Correlation analysis showed a direct correlation between the markers of endothelial damage and the SOFA scores (r=0.34; p=0.05 for WF and r=0.49;p=0.03 for endothelin. Conclusion. The GIT function support regimen via early enteral alimentation with Peptisorb, which was initiated in the first 24 hours after admission, is able to level off the manifestations of the early stages of the abdominal compartment syndrome, with the acceptable values of oxygen balance and water-electrolyte and osmotic homeostasis being achieved.

  8. Mechanosensitivity in the enteric nervous system

    Directory of Open Access Journals (Sweden)

    Gemma eMazzuoli-Weber

    2015-10-01

    Full Text Available The enteric nervous system (ENS autonomously controls gut muscle activity. Mechanosensitive enteric neurons (MEN initiate reflex activity by responding to mechanical deformation of the gastrointestinal wall. MEN throughout the gut primarily respond to compression or stretch rather than to shear force. Some MEN are multimodal as they respond to compression and stretch. Depending on the region up to 60% of the entire ENS population responds to mechanical stress. MEN fire action potentials after mechanical stimulation of processes or soma although they are more sensitive to process deformation. There are at least two populations of MEN based on their sensitivity to different modalities of mechanical stress and on their firing pattern. 1 Rapidly, slowly and ultra-slowly adapting neurons which encode compressive forces. 2 Ultra-slowly adapting stretch-sensitive neurons encoding tensile forces. Rapid adaptation of firing is typically observed after compressive force while slow adaptation or ongoing spike discharge occurs often during tensile stress (stretch. All MEN have some common properties: they receive synaptic input, are low fidelity mechanoreceptors and are multifunctional in that some serve interneuronal others even motor functions. Consequently, MEN possess processes with mechanosensitive as well as efferent functions. This raises the intriguing hypothesis that MEN sense and control muscle activity at the same time as servo-feedback loop. The mechanosensitive channel(s or receptor(s expressed by the different MEN populations are unknown. Future concepts have to incorporate compressive and tensile-sensitive MEN into neural circuits that controls muscle activity. They may interact to control various forms of a particular motor pattern or regulate different motor patterns independently from each other.

    To evaluate the efficacy of sequential enteral nutrition support in patients with severe cerebral stroke. Forty-nine patients with severe cerebral stroke met the inclusion criteria were randomly divided into sequential enteral nutrition group (Group A, n=24) and conventional enteral nutrition group (Group B, n=25). Patients in Group A received short-peptide-based enteral nutrition support first, then gradually transferred to intact protein enteral nutrition. Meanwhile, patients in Group B constantly received intact protein enteral nutrition support. The nutritional indexes and the rate of complications were compared between two groups. The nutritional indexes were decreased in both groups within 4 weeks after admission, but the decreasing levels of hemoglobin and albumin in Group A were significantly lower than those in Group B (P0.05). Sequential enteral nutritional support can improve the nutritional status and decrease the incidence of complications in critical patients with cerebral stroke.

    Over the last 20 years, there has been increasing focus on the development of novel stem cell based therapies for the treatment of disorders and diseases affecting the enteric nervous system (ENS) of the gastrointestinal tract (so-called enteric neuropathies). Here, the idea is that ENS progenitor/stem cells could be transplanted into the gut wall to replace the damaged or absent neurons and glia of the ENS. This White Paper sets out experts’ views on the commonly used methods and approaches to identify, isolate, purify, expand and optimize ENS stem cells, transplant them into the bowel, and assess transplant success, including restoration of gut function. We also highlight obstacles that must be overcome in order to progress from successful preclinical studies in animal models to ENS stem cell therapies in the clinic. PMID:27059883

    Full Text Available Pancreaticoduodenectomy (PD is considered the gold standard treatment for periampullory carcinomas. This procedure presents 30%–40% of morbidity. Patients who have undergone pancreaticoduodenectomy often present perioperative malnutrition that is worse in the early postoperative days, affects the process of healing, the intestinal barrier function and the number of postoperative complications. Few studies focus on the relation between enteral nutrition (EN and postoperative complications. Our aim was to perform a review, including only randomized controlled trial meta-analyses or well-designed studies, of evidence regarding the correlation between EN and main complications and outcomes after pancreaticoduodenectomy, as delayed gastric emptying (DGE, postoperative pancreatic fistula (POPF, postpancreatectomy hemorrhage (PPH, length of stay and infectious complications. Several studies, especially randomized controlled trial have shown that EN does not increase the rate of DGE. EN appeared safe and tolerated for patients after PD, even if it did not reveal any advantages in terms of POPF, PPH, length of stay and infectious complications.

    Full Text Available Intestinal bacteria can contribute to cell proliferation and cancer development, particularly in chronic infectious diseases in which bacteria and/or bacterial components might interfere with cell function. The number of microbial cells within the gut lumen is estimated to be 100 trillion, which is about 10-times larger than the number of eukaryotic cells in the human body. Because of the complexity of the gut flora, identifying the specific microbial agents related to human diseases remains challenging. Recent studies have demonstrated that the stemness of colon cancer cells is, in part, orchestrated by the microenvironment and is defined by high Wnt activity. In this review article, we will discuss recent progress with respect to intestinal stem cells, cancer stem cells, and the molecular mechanisms of enteric bacteria in the activation of the Wnt pathway. We will also discuss the roles of other pathways, including JAK-STAT, JNK, and Notch, in regulating stem cell niches during bacterial infections using Drosophila models. Insights gained from understanding how host-bacterial interaction during inflammation and cancer may serve as a paradigm for understanding the nature of self-renewal signals.

    Full Text Available Campylobacter enteritis is a common form of acute gastroenteritis. Among children, especially in developing countries, Campylobacter infections can cause sever life-threatening diarrheal disease. The incidence of Campylobacter infection among children is age related with a higher incidence among younger children in the developing world whereas in industrialized countries the incidence is highest in older children. In a study of American children, Campylobacter was isolated in 4.8% of diarrheal stools in aged 1-4 years. In 1985 the prevalence of Campylobacter diarrheal was 4.4%, whereas in current report 6% of stool samples from children aged<5 years with diarrhea grew Campylobacter jejuni. There were no significant differences between age groups of patients. All thirteen isolated strains of Campylobacter were resistance to Bactrim, Colistin and Polymyxin B and were sensitive to Neomycin, Erythromycin, Gentamicin and Nalidixic acid. The incidence of human campylobacteriosis is increasing worldwide. Thus, public health awareness about the problem is necessary, with a view towards setting up national surveillance programs.

    Solutions of Clinifeed ISO, Triosorbon, Vivonex Standard (full- and half-strength) and Vivonex HN were experimentally contaminated with two strains each of Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella aerogenes, Escherichia coli and Enterobacter cloacae at concentrations of 10(2)-10(3) organisms/ml. Samples were incubated at 4, 25 or 37 degrees C and viable counts were made at 0, 4, 8 and 24 h. No increase in numbers of any of the organisms was observed in any of the feeds during 24 h at 4 degrees C. All organisms multiplied rapidly in Clinifeed ISO and in Triosorbon at 25 and 37 degrees C. There was less rapid growth in half-strength Vivonex Standard at 25 degrees C, although at 37 degrees C all strains multiplied rapidly except for the two S. aureus strains, the growth of which was inhibited in half-strength Vivonex Standard at both 25 and 37 degrees C. In full-strength Vivonex Standard at 25 degrees C, only P. aeruginosa showed any increase in numbers during 24 h, whereas P. aeruginosa, K. aerogenes and E. cloacae all multiplied at 37 degrees C. None of the test organisms multiplied in full strength Vivonex HN at any of the temperatures studied. The results of the study show that bacteria survive and may multiply even in feeds with low pH and high osmolarity, and emphasise the importance of strict hygiene during the preparation and handling of all enteral feeds.

    Twenty-four patients with severe radiation injury to the small bowel seen over a 4-year period were randomized to four treatment groups: 1) methylprednisolone 80 mg intravenously plus Vivonex-HN, 2 L/day po, 2) methylprednisolone 80 mg intravenously plus total parenteral nutrition, 2.5 L/day, 3) total parenteral nutrition, 2.5 L/day, and 4) Vivonex-HN, 2 L/day po. Patients received nothing by mouth except water in groups II and III, and only Vivonex-HN in groups I and IV. Patients were treated for 8-wk periods. Improvement was gauged by overall nutritional assessment measurements, nitrogen balance data and by radiological and clinical parameters. No significant difference between groups I, II, III, and IV could be found for age, sex, mean radiation dosage, time of onset after radiation therapy, or initial nutritional assessment data. Differences statistically could be found between groups II and III and I and IV regarding nutritional assessment data, nitrogen balance, radiographic and clinical parameters after therapy, with marked improvement noted in groups II and III. We conclude that a treatment regimen consisting of total parenteral nutrition and bowel rest is beneficial in the treatment of radiation enteritis. Methylprednisolone appears to enhance this effect and indeed, may be responsible for a longer lasting response.

    Full Text Available An enteric syndrome observed in semi-intensively reared quails is described. The affected birds showed depression, severe diarrhoea and dehydration. The mortality occurred particularly in young birds. At necropsy, the prominent lesion was catarrhal enteritis. Laboratory investigations demonstrated the presence of coronavirus in the gut of dead animals. No additional pathogens were detected. To our knowledge, this is the first evidence for the presence of CoVs in quail with enteritis.

    Full Text Available Abstract Background Water contamination with human enteric viruses has posed human health risks all over the world. Reasonable and facile methodologies for recovering and quantifying infectious enteric viruses in environmental samples are needed to address the issues of waterborne viral infectious diseases. In this study, a bacterial protein that has a binding capability with several enteric viruses is discovered, and its binding characteristics were investigated for utilizing it as a viral adsorbent in virus recovery and detection technologies. Results A gene of an enteric virus-binding protein (EVBP, derived from a monomer of a bacterial chaperon protein GroEL, was successfully acquired from a genomic DNA library of activated sludge microorganisms with nested PCR. Equilibrium dissociation constants between EVBP and norovirus-like particles (NoVLPs of genotypes GI.7 and GII.4, estimated with quartz crystal microbalance method, were 240 and 210 nM, respectively. These values of equilibrium dissociation constant imply that the binding affinity between EVBP and NoVLPs is 1 to 3-log weaker than that in general antigen-antibody interactions, but about 2-log stronger than that in weak specific interactions of proteins with cations and organic polymers. The adsorptions of EVBP to norovirus, group A rotavirus and poliovirus type 1 were found to be significant in enzyme-linked immunosorbent assay. Meanwhile, the binding of native GroEL tetradecamer to viral particles was weaker than that of EVBP, presumably because of a steric hindrance. The small molecule of EVBP could have an advantage in the access to the surface of viral particles with rugged structure. Conclusions EVBP that has a broad binding spectrum to enteric viruses was newly discovered. The broad binding characteristic of EVBP would allow us to utilize it as a novel adsorbent for detecting diverse enteric viruses in clinical and environmental samples.

    Enteral nutrition (EN) is indicated in patients who, although they may not eat enough food, maintain a sufficient function to receive, digest and absorb nutrients digestive system. Oral Nutritional Supplements (SON) are nutritionally complete or incomplete formulas (depending on whether or not provide all the nutrients needed to serve as the sole source of nutrients), which supplement inadequate oral diet. This study aims to evaluate the organoleptic characteristics of hyperproteic, normoproteic and fiber-enriched oral SON. SON test, carried out at the Department of Endocrinology and Nutrition Consortium Hospital General Universitario de Valencia from October 2012 to February 2013. 137 SON were evaluated in total, of which 47 were hyperproteic, 46 normoproteic and 44 enriched in fiber. Of the SON evaluated in the group of hyperproteic the following 3 SON obtained the best scores: Fresenius Prot Energy Drink® (21,27, vanilla flavor), Avant Standard Nut® (20.3 , strawberry flavor) and Resource® Protein (20.01, chocolate flavor) In the group of normoproteic SON the 3 best rated were: Ensure Plus® (22.3, banana flavor), Ensure Plus® (21.9, peach flavor) and Fresubin Energy Drink® (21, strawberry flavor) In the group of fiber-enriched the 3 SON most appreciated were: 2 Kcal Fresubin Fibre Drink® (23.78, vanilla flavor), Ensure Plus® TwoCal (22.9, banana flavor) and Fortimel Compact® (21.5, strawberry flavor) The study aims to guide clinicians on what SON may be more acceptable to the patient, so that the SON serve their purpose and restore or improve nutritional status, as the SON intervention is safe and cost - effective, since they improve both the functionality and quality of life.

    Rotaviruses (RVs) are among the leading causes of enteritis and diarrhea in a number of mammalian and avian species, and impose colossal loss to livestock and poultry industry globally. Subsequent to detection of rotavirus in mammalian hosts in 1973, avian rotavirus (AvRV) was first reported in turkey poults in USA during 1977 and since then RVs of group A (RVA), D (RVD), F (RVF) and G (RVG) have been identified around the globe. Besides RVA, other AvRV groups (RVD, RVF and RVG) may also contribute to disease. However, their significance has yet to be unraveled. Under field conditions, co-infection of AvRVs occurs with other infectious agents such as astroviruses, enteroviruses, reoviruses, paramyxovirus, adenovirus, Salmonella, Escherichia coli, cryptosporidium and Eimeria species prospering severity of disease outcome. Birds surviving to RV disease predominantly succumb to secondary bacterial infections, mostly E. coli and Salmonella spp. Recent developments in molecular tools including state-of-the-art diagnostics and vaccine development have led to advances in our understanding towards AvRVs. Development of new generation vaccines using immunogenic antigens of AvRV has to be explored and given due importance. Till now, no effective vaccines are available. Although specific as well as sensitive approaches are available to identify and characterize AvRVs, there is still need to have point-of-care detection assays to review disease burden, contemplate new directions for adopting vaccination and follow improvements in public health measures. This review discusses AvRVs, their epidemiology, pathology and pathogenesis, immunity, recent trends in diagnostics, vaccines, therapeutics as well as appropriate prevention and control strategies.

    Syndromic diarrhea/Tricho-hepato-enteric syndrome (SD/THE) is a rare and severe bowel disorder caused by mutation in SKIV2L or in TTC37, 2 genes encoding subunits of the putative human SKI complex. The estimated prevalence is 1/1,000,000 births and the transmission is autosomal recessive. The classical form is characterized by 5 clinical signs: intractable diarrhea of infancy beginning in the first month of life, usually leading to failure to thrive and requiring parenteral nutrition; facial dysmorphism characterised by prominent forehead and cheeks, broad nasal root and hypertelorism; hair abnormalities described as woolly and easily removable; immune disorders resulting from defective antibody production; intrauterine growth restriction. The aetiology is a defect in TTC37, a TPR containing protein, or in the RNA helicase SKIV2L, both constituting the putative human ski complex. The ski complex is a heterotetrameric cofactor of the cytoplasmic RNA exosome which ensures aberrants mRNAs decay. The diagnosis SD/THE is initially based on clinical findings and confirmed by direct sequencing of TTC37 and SKIV2L. Differential diagnosis with the other causes of intractable diarrhea is easily performed by pathologic investigations. During their clinical course, most of the children require parenteral nutrition and often immunoglobulin supplementation. With time, some of them can be weaned off parenteral nutrition and immunoglobulin supplementation. The prognosis depends on the management and is largely related to the occurrence of parenteral nutrition complications or infections. Even with optimal management, most of the children seem to experience failure to thrive and final short stature. Mild mental retardation is observed in half of the cases.

    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

    Home enteral nutrition is the administration of enteral formulae into the digestive tract using a tube, with the objective of preventing or correcting malnutrition patients who are seen at home. Home enteral nutrition is a type of nutritional support that is growing, that improves the nutritional status of the patient with a lower cost and with a greater quality of life of the family unit than enteral nutrition in the hospital. The prevalence is clearly increasing although the data of the national registers of patients with at home enteral nutrition are under estimated. Patients who are candidates for home enteral nutrition can be all those with an indication for enteral nutrition and whose underlying disease is stabilized or does not require all the technical means of the hospital in a permanent and essential manner. Neoplasias and neurological diseases are those that benefit most from at home enteral nutrition and in all registries each group varies between 30 and 40%. All access routes and all enteral nutrition formulae can be used in patients with home enteral nutrition. The use of percutaneous endoscopic gastrostomies is ever more recommended in patients who need at home enteral nutrition for a period longer than 4 weeks. Since the publication of the Ministerial Order of June 2nd 1998, home enteral nutrition is considered a health care service that can be covered by the Social Security. This order lists a series of disease that are likely to be treated with at home enteral nutrition (in our opinion the list is not complete but it is likely to be changed in the future by an Assessing Committee), and it presents some basic norms that all patients must comply with, regardless of the autonomous community in which they live. Before beginning at home enteral nutrition the training of the patient and/or the family with regard to the management of at home enteral nutrition is essential.

    Full Text Available Perioperative nutrition has during the last century been transformed from a tool to provide calorie and nitrogen support to a tool to boost the immune system and increase resistance to complications. Despite all progress in medicine and surgery has perioperative morbidity, rate of infections, thrombosis and development of serosal adhesions remained the same as long as can be judged or at least during the last eighty years. Most prone to develop complications are persons above the age of 65 and persons with depressed immunity. About cighty percent of the immune system is localised in the gastrointestinal tract, which offers great opportunities for modulation through enterar nutrition. As the stomach has a tendency to develop postoperative paralysis, tube feeding is often necessary. Andresen demonstrated already in 1918 the advantages of enteral nutrition, which starts already on the table. Mulholland et al and Rhoads and co-workers demonstrated during the 1940s certain advantages of enteral tube feeding. Also works by Alexander, Fischer, Ryan and their co-workers supported the value of early enteral feeding, and suggested enteral feeding as an effective tool to boost the immune system. it was, however, works published in the early nineties by Moore et al and by Kudsk et al, which made surgeons more aware of the advantages of early enteral nutrition. Major surgery is known to have a high rate of complications. Uninterrupted perioperative nutrition, eg nutrition during the night before, during surgery and immediately after offers a strong tool to prevent complications. lt is essential that the nutrition provides food also for the colon, e.g. fibres and healthy bacteria (probiotics to ferment the fibre and boost the immune system.Durante el último siglo la nutrición perioperatoria ha pasado de ser un mero instrumento para proporcionar calorías y soporte nitrogenado a una herramienta reforzadora del sistema inmunológico aumentando la resistencia

    Cats with feline leukemia virus (FeLV)-associated enteritis (FAE), enteritis of other known viral etiology (parvovirus [PV], enteric coronavirus [CoV]), and enteritis of unknown etiology with histologic features similar to those of FAE and PV enteritis (EUE) and FeLV-negative and FeLV-positive cats without enterocyte alterations were examined. Amount and types of infiltrating leukocytes in the jejunum and activity and cellular constituents of mesenteric lymph nodes, spleen, and bone marrow were determined. PV and CoV infections were confirmed by immunohistologic demonstration of PV and CoV antigen, ultrastructural demonstration of viral particles in the intestinal content, and in situ hybridization for PV genome. FeLV infection was detected by immunohistology for gp70, p27, and p15E. Latent FeLV infection was excluded by polymerase chain reaction methods for exogenous FeLV DNA. Enterocyte lesions involved the crypts in cats with PV enteritis, FAE, and EUE and the villous tips in cats with CoV enteritis. Inflammatory infiltration was generally dominated by mononuclear cells and was moderate in the unaltered intestine and in cats with PV enteritis and marked in cats with FAE, CoV enteritis, and EUE. In cats with EUE, myeloid/histiocyte antigen-positive macrophages were relatively numerous, suggesting recruitment of peripheral blood monocytes. Lymphoid tissues were depleted in cats with PV enteritis and with EUE but were normal or hyperplastic in cats with FAE. Bone marrow activity was decreased in cats with PV enteritis; in cats with FAE or EUE and in FeLV-positive cats without enterocyte alterations, activity was slightly increased. In cats with FAE and PV enteritis, a T-cell-dominated response prevailed. EUE showed some parallels to human inflammatory bowel disease, indicating a potential harmful effect of infiltrating macrophages on the intestinal epithelium.

    The NADYA-SENPE Working Group analyzed the registered data of patients on Home Enteral Nutrition (HEN) in our country, during year 2001. The data were collected through a closed questionnaire included on our web site (www.nadya-senpe.com). Apart from epidemiological information, the form includes the indication to prescribe this treatment, the specific nutritional treatment used and its duration, access path, complications and readmission rate in hospital, follow-up of the treatment, patient's quality of life and progress. All data were processed and analyzed by the coordinating team. Twenty two hospitals participated and 3,458 patients, aged 5.6 +/- 4.0 y for those younger than 14 y, and 67.1 +/- 19.5 y for those older than 14 y, were enrolled. Of these patients, 43.4% were diagnosed with neurological diseases and 33.5% with cancer. The mean time on HEN was 6.5 +/- 4.5 months. Oral nutrition was the preferential route (54.5%), followed by nasoenteral tube (32.3%), and in 13.3% ostomy tubes were placed. Polymeric was the formula composition mainly used (85.9%). Patients were followed (71.1%) by the hospital reference Nutritional Support Unit. The complications related to nutrition included mainly the gastrointestinal (0.16 complications/patient), and the mechanical one (0.15 complications/patient). At the end for the year, 48.3% of the patients were in the HEN program, and in 33.3% HEN was finish due to different reasons. In 22.9% of the patients no, o light, discapacity degree was found. Neurological diseases and cancer were the more frequent diagnoses in HEN patients. Oral access was the higher feeding route due, probably, to the high prevalence of cancer patients. In spite of the elevated prevalence of neurological diseases, a few number of patients, as previous years, were feed with ostomy tube. Due to the few complications observed, HEN is a safe treatment in our country.

    Frank, Daniel N; Pace, Norman R

    2008-01-01

    Advances in DNA sequence-based technologies now permit genetic analysis of complex microbial populations without the need for prior cultivation. This review summarizes the molecular methods of culture-independent microbiology ('metagenomics') and their recent application to studies of the human gastrointestinal tract in both health and disease. Culture-independent metagenomic surveys reveal unprecedented microbial biodiversity in the human intestine. Upwards of 40,000 bacterial species are estimated to comprise the collective gastrointestinal microbiome, most of which have not been characterized by culture. Diverse conditions such as antibiotic-associated diarrhea, Crohn's disease, ulcerative colitis, obesity, and pouchitis have been correlated with large-scale imbalances in gastrointestinal microbiota, or 'dysbiosis'. These findings demonstrate the importance of commensal microorganisms in maintaining gastrointestinal health. Through technological and conceptual innovations in metagenomics, the complex microbial habitat of the human gastrointestinal tract is now amenable to detailed ecological analysis. Large-scale shifts in gut commensal populations, rather than occurrence of particular microorganisms, are associated with several gastroenterological conditions; redress of these imbalances may ameliorate the conditions.

  16. A Comparison of Postoperative Early Enteral Nutrition with Delayed Enteral Nutrition in Patients with Esophageal Cancer

    Full Text Available We examined esophageal cancer patients who received enteral nutrition (EN to evaluate the validity of early EN compared to delayed EN, and to determine the appropriate time to start EN. A total of 208 esophagectomy patients who received EN postoperatively were divided into three groups (Group 1, 2 and 3 based on whether they received EN within 48 h, 48 h–72 h or more than 72 h, respectively. The postoperative complications, length of hospital stay (LOH, days for first fecal passage, cost of hospitalization, and the difference in serum albumin values between pre-operation and post-operation were all recorded. The statistical analyses were performed using the t-test, the Mann-Whitney U test and the chi square test. Statistical significance was defined as p < 0.05. Group 1 had the lowest thoracic drainage volume, the earliest first fecal passage, and the lowest LOH and hospitalization expenses of the three groups. The incidence of pneumonia was by far the highest in Group 3 (p = 0.019. Finally, all the postoperative outcomes of nutritional conditions were the worst by a significant margin in Group 3. It is therefore safe and valid to start early enteral nutrition within 48 h for postoperative esophageal cancer patients.

  20. A novel subset of enteric neurons revealed by ptf1a:GFP in the developing zebrafish enteric nervous system.

    Science.gov (United States)

    Uribe, Rosa A; Gu, Tiffany; Bronner, Marianne E

    2016-03-01

    The enteric nervous system, the largest division of the peripheral nervous system, is derived from vagal neural crest cells that invade and populate the entire length of the gut to form diverse neuronal subtypes. Here, we identify a novel population of neurons within the enteric nervous system of zebrafish larvae that express the transgenic marker ptf1a:GFP within the midgut. Genetic lineage analysis reveals that enteric ptf1a:GFP(+) cells are derived from the neural crest and that most ptf1a:GFP(+) neurons express the neurotransmitter 5HT, demonstrating that they are serotonergic. This transgenic line, Tg(ptf1a:GFP), provides a novel neuronal marker for a subpopulation of neurons within the enteric nervous system, and highlights the possibility that Ptf1a may act as an important transcription factor for enteric neuron development.

  2. Enteric microbiota leads to new therapeutic strategies for ulcerative colitis.

    2014-11-14

    Ulcerative colitis (UC) is a leading form of inflammatory bowel disease that involves chronic relapsing or progressive inflammation. As a significant proportion of UC patients treated with conventional therapies do not achieve remission, there is a pressing need for the development of more effective therapies. The human gut contains a large, diverse, and dynamic population of microorganisms, collectively referred to as the enteric microbiota. There is a symbiotic relationship between the human host and the enteric microbiota, which provides nutrition, protection against pathogenic organisms, and promotes immune homeostasis. An imbalance of the normal enteric microbiota composition (termed dysbiosis) underlies the pathogenesis of UC. A reduction of enteric microbiota diversity has been observed in UC patients, mainly affecting the butyrate-producing bacteria, such as Faecalibacterium prausnitzii, which can repress pro-inflammatory cytokines. Many studies have shown that enteric microbiota plays an important role in anti-inflammatory and immunoregulatory activities, which can benefit UC patients. Therefore, manipulation of the dysbiosis is an attractive approach for UC therapy. Various therapies targeting a restoration of the enteric microbiota have shown efficacy in treating patients with active and chronic forms of UC. Such therapies include fecal microbiota transplantation, probiotics, prebiotics, antibiotics, helminth therapy, and dietary polyphenols, all of which can alter the abundance and composition of the enteric microbiota. Although there have been many large, randomized controlled clinical trials assessing these treatments, the effectiveness and safety of these bacteria-driven therapies need further evaluation. This review focuses on the important role that the enteric microbiota plays in maintaining intestinal homeostasis and discusses new therapeutic strategies targeting the enteric microbiota for UC.

  3. Enteral Nutrition for Adults in the Hospital Setting.

    Kozeniecki, Michelle; Fritzshall, Rebecca

    2015-10-01

    In patients unable to tolerate oral intake, multiple options of nutrient delivery are available to the clinician. Administration of enteral nutrition (EN) has long been considered the standard of care for nutrition support among patients unable to meet energy and protein requirements orally. Healthcare practitioners must make careful decisions related to ordering, administering, and monitoring EN therapy. In the hospital setting, the registered dietitian is a key resource in enteral formula selection and method of administration, monitoring for and troubleshooting EN-related complications, and transitioning to oral feeding. The hospital setting also presents many unique challenges in providing optimal nutrition to the enterally fed patient.

  4. Conservative management of eosinophilic enteritis presenting with acute abdominal syndrome

    2013-04-01

    Full Text Available Eosinophilic enteritis, an increasing recognized condition, is rare and often presents with non-specific symptoms. We report a case of a 46-year old female who presented with acute onset abdominal pain and nausea associated with ascites, small bowel thickening and peripheral eosinophilia. Diagnosis was confirmed by biopsies taken at esophagogastroduodenoscopy demonstrating diffuse infiltration by inflammatory cells, mainly eosinophils. Appropriate therapy was instituted. The patient recovered well and was symptom-free at 1-month follow up. In this report, we discuss the clinical presentation and the diagnostic criteria of the eosinophilic enteritis, and examine the pathophysiological theories and therapeutic strategies. The relevant literature on eosinophilic enteritis is summarized.

    Neural crest cells comprise a multipotent, migratory cell population that generates a diverse array of cell and tissue types, during vertebrate development. Enteric Nervous System controls the function of the gastrointestinal tract and is mainly derived from the vagal and sacral neural crest cells. Deregulation on self-renewal and differentiation of the enteric neural crest cells is evident in enteric nervous system disorders, such as Hirschsprung disease, characterized by the absence of ganglia in a variable length of the distal bowel. Here we show that Geminin is essential for Enteric Nervous System generation as mice that lacked Geminin expression specifically in neural crest cells revealed decreased generation of vagal neural crest cells, and enteric neural crest cells (ENCCs). Geminin-deficient ENCCs showed increased apoptosis and decreased cell proliferation during the early stages of gut colonization. Furthermore, decreased number of committed ENCCs in vivo and the decreased self-renewal capacity of enteric progenitor cells in vitro, resulted in almost total aganglionosis resembling a severe case of Hirschsprung disease. Our results suggest that Geminin is an important regulator of self-renewal and survival of enteric nervous system progenitor cells. Copyright © 2015 Elsevier Inc. All rights reserved.

    The aim of the study was to investigate the effect of microbial immune enteral nutrition by microecopharmaceutics and deep sea fish oil and glutamine and Peptisorb on the patients with acute radiation enteritis in bowel function and immune status. From June 2010 to January 2013, 46 acute radiation enteritis patients in Liaocheng People's Hospital were randomized into the microbial immune enteral nutrition group and the control group: 24 patients in treatment group and 22 patients in control group. The immune microbial nutrition was given to the study group, but not to the control group. The concentration of serum albumin and prealbumin and the number of CD3 (+) T cell, CD4 (+) T cell, CD8 (+) T cell, CD4 (+)/CD8 (+) and natural killer cell of the two groups were detected on the 1, 7 and 14 days after treatment. The arm muscle circumference and triceps skinfold thickness (TSF) were recorded, and the tolerance of the two groups for enteral nutrition and intestinal symptoms was collected and then comparing the two indicators and get results. The tolerance of microbial immune enteral nutrition group about abdominal pain, bloating and diarrhea was better than the control group (P values were 0.018, 0.04 and 0.008 after 7 days; P values were 0.018, 0.015 and 0.002 after 14 days); and the cellular immune parameters were better than the control group((△) P = 0.008,([Symbol: see text]) P = 0.039, (☆) P = 0.032); No difference was found in nutrition indicators. To the patients with acute radiation enteritis, microbial immune enteral nutrition could improve the patient's immune status, and the tolerance of enteral nutrition could be better for the bowel function and the patients' rehabilitation.

    1985-09-01

    The two-hour Rapid SST strip (DMS Laboratories, Inc.) was compared with our standard screening system (triple sugar iron agar, lysine iron agar, and urea) for enteric pathogens. We tested 50 stock cultures of enteric pathogens and 213 stool cultures received in the Barnes Hospital Clinical Microbiology Laboratory over a two-month period. All enteric pathogens from the stock cultures and clinical specimens were identified correctly with the Rapid SST system. More false-positive reactions were observed with the Rapid SST system (34%) than with the conventional system (23%). However, the costs associated with using both systems were equivalent and the test results were available one day faster with the Rapid SST system. Thus, the Rapid SST is a rapid, accurate, and cost-effective method for screening stool specimens for enteric pathogens.

    Kornowski, A; Cosnes, J; Gendre, J P; Quintrec, Y

    1992-02-01

    Nutritional recovery was studied during continuous enteral nutrition in 29 patients who had developed malnutrition after gastric surgery. Patients were divided into three groups according to the type of surgery involved: total gastrectomy (n = 10), partial gastrectomy (n = 12), or cephalic pancreaticoduodenectomy (n = 7). The evolution of anthropometric and biological nutritional parameters in each group was compared with that observed in a control group of 10 nonoperated anorectic patients. Significant gains in body weight, arm muscle circumference, triceps skinfold, serum transferrin and global nutritional status were observed after 3 to 4 weeks of enteral nutrition in each group, while serum albumin, serum cholesterol, hemoglobin, and total lymphocyte count did not change significantly. No significant difference was observed between the groups. However, weight gain tended to be slower in patients with cephalic pancreaticoduodenectomy. This study confirms that enteral nutrition is an effective method of nutritional repletion after gastrectomy. Enteral nutrition can be used in undernourished gastrectomized patients when dietary measures alone have proven inadequate.

  15. [Enteral Nutritional Support in Gastrointestinal and Liver Diseases].

    Science.gov (United States)

    Kim, Eun Ran

    2015-06-01

    Nutritional support is important because malnutrition is a major contributor to increased morbidity and mortality, decreased quality of life, increased length of hospital stay, and higher healthcare costs. Patients with gastrointestinal disease are at an increased risk of nutritional deterioration due to therapeutic dietary restriction, fasting for the diagnostic tests, loss of appetite due to anorexia or altered nutritional requirement caused by the disease itself. Therefore, it is important that gastroenterologists are aware of the nutritional status of patients and plan a treatment strategy considering patient's nutritional status. Enteral nutrition is preferred to parenteral nutrition as it is more physiologic, has fewer complications, help to prevent mucosal atrophy and maintain gut barrier function, which decrease intestinal bacterial translocation. Hence, enteral nutrition has been considered to be the most effective route for nutritional support. In this article, we will review enteral nutrition (oral nutritional supplements, enteral tube feeding) as a treatment for the patients with gastrointestinal, liver and pancreatic disease at risk of malnutrition.

    To communicate the results from the registry of Home-Based Enteral Nutrition of the NADYASENPE group in 2007. We included every patient in the registry with home enteral nutrition any time from January 1st to December 31st of 2007. The number of patients with home enteral nutrition in 2007 was 5,107 (52% male) from 28 different hospitals. 95.4% of them were 15 yr or older, with a mean age of 67.96 +/- 18.12, and 4.2 +/- 3.38 among patients aged 14 yr or less. The most common underlying diseases were neurological (37.8%) and neoplastic diseases (29.3%). Enteral nutrition was administered p.o. in most patients (63.5%), followed by nasogastric tube (25.9%), while gastrostomy was only used in 9.2%. The mean time in enteral nutrition support was 9.4 months and the most common reasons for withdrawal were death (58.7%) and switching to oral intake (32%). Activity was limited in 31.4% of patients and 36.01% were house-bound. Most patients needed partial (26.51%) or total (37.68%) care assistance. Enteral formula was provided by hospitals to 69.14% of patients and by pharmacies to 30.17% of them, while disposable material was provided by hospitals to 81.63% and by Primary Care to the remaining patients. In 2007, there has been an increase of more than 30% of patients registered with home enteral nutrition comparing with 2006, without any big difference in other data, but a higher proportion of patients with enteral nutrition p.o.

  5. Necrotic enteritis in broilers: an updated review on the pathogenesis.

    2011-08-01

    Clostridium perfringens-induced necrotic enteritis and related subclinical disease have become economically significant problems for the broiler industry. Fortunately, scientific interest in this topic has grown: new C. perfringens virulence factors have been discovered and new insight gained about the pathogenesis of necrotic enteritis. It has been shown that alpha toxin, for a long time thought to be the key virulence factor, is not essential for the development of the disease. Moreover, it is now clearly established that only certain C. perfringens strains are capable of inducing necrotic enteritis under specific conditions that predispose to the disease and they constitute only a minority in the intestinal tract of healthy chickens. A novel pore-forming toxin, NetB, has been identified in these virulent avian C. perfringens strains. Using a gene knockout mutant, it has been shown that NetB is a critical virulence factor in the pathogenesis of necrotic enteritis in broilers. In addition to toxin production, other factors have been described that contribute to the ability of certain C. perfringens strains to cause necrotic enteritis in broilers. It has been suggested that proteolytic enzymes play an important role in the initial stages of necrotic enteritis since the villi are first affected at the level of the basement membrane and the lateral domain of the enterocytes. In field outbreaks of necrotic enteritis, a single clone of C. perfringens is dominant in intestines of all affected birds, as opposed to the mixture of different C. perfringens strains that can be isolated from healthy bird intestines. It has been proposed that bacteriocin production is responsible for the dominance of a single strain in necrotic enteritis cases. Furthermore, it has been shown that virulent strains are more able to adhere to extracellular matrix molecules than non-virulent strains. The current knowledge on the pathogenesis of the disease has been summarized in this short review.

From January 2009 to December 2012 the data of all burn patients with the diagnosis of sepsis who were placed on enteral nutrition were analyzed. Septic patients were divided into two groups: group A, septic patients who developed feeding intolerance; group B, septic patients who did not develop feeding intolerance. Demographic and clinical characteristics of patients were analyzed and compared. The diagnosis of sepsis was applied to 29% of all patients. Of these patients 35% developed intolerance to enteral feeding throughout the septic period. A statistically significant increase in mean PCT level and a decrease in prealbumin level was observed during the sepsis period. Group A patients had statistically significant lower mean caloric intake, higher PCT:prealbumin ratio, higher pneumonia incidence, higher Sequential Organ Failure Assessment Maximum Score, a longer duration of mechanical ventilation, and a higher mortality rate in comparison with the septic patients without gastric feeding intolerance. The authors concluded that a high percentage of septic burn patients developed enteral feeding intolerance. Enteral feeding intolerance seems to have a negative impact on the patients' nutritional status, morbidity, and mortality.

    Cell therapy has the potential to treat gastrointestinal motility disorders caused by diseases of the enteric nervous system. Many studies have demonstrated that various stem/progenitor cells can give rise to functional neurons in the embryonic gut; however, it is not yet known whether transplanted neural progenitor cells can migrate, proliferate, and generate functional neurons in the postnatal bowel in vivo. We transplanted neurospheres generated from fetal and postnatal intestinal neural crest–derived cells into the colon of postnatal mice. The neurosphere-derived cells migrated, proliferated, and generated neurons and glial cells that formed ganglion-like clusters within the recipient colon. Graft-derived neurons exhibited morphological, neurochemical, and electrophysiological characteristics similar to those of enteric neurons; they received synaptic inputs; and their neurites projected to muscle layers and the enteric ganglia of the recipient mice. These findings show that transplanted enteric neural progenitor cells can generate functional enteric neurons in the postnatal bowel and advances the notion that cell therapy is a promising strategy for enteric neuropathies.

    Because municipal solid waste may contain fecal material from a variety of sources, there is concern that the leachate discharged from some solid waste landfills may contain enteric pathogens, including enteric viruses. In this study, 22 leachate samples from 21 different landfills in the United States and Canada were examined for enteric viruses. The sites represented a broad range of conditions for solid waste landfills and the leachate samples ranged from 10.3 to 18 liters in volume. Enteric viruses were found in only one of the 22 leachate samples examined. Two viruses, identified as poliovirus types 1 and 3, were found in an 11.8 liter sample obtained from a site where solid waste landfill practice was deficient. The low levels of enteric viruses detected in field samples of raw leachate and the opportunities for further reductions in the virus concentration of leachates by such processes as thermal inactivation, removal by soil and dilution in ground and surface waters, suggest that leachates from properly operated solid waste landfills do not constitute an environmental or public health hazard due to enteric viruses.

    Full Text Available Systemic lupus erythematosus (SLE is an autoimmune disorder which can affect multiple organs and clinical presentation is often a myriad of symptoms; therefore, the index of suspicion should rise when evaluating patients with multiorgan symptomatology. Lupus enteritis is a distinct subset of SLE, defined as either vasculitis or inflammation of the small bowel, with supportive image and/or biopsy findings. The clinical picture of lupus enteritis is often nonspecific, with mild to severe abdominal pain, diarrhea, and vomiting being the cardinal manifestations. Although considered a form of visceral or serosal vasculitis, lupus enteritis is seldom confirmed on histology, making computerized tomography (CT the gold standard for diagnosis. Lupus enteritis is generally steroid-responsive, and the route of administration is based on clinical status and organ involvement, with preference for intravenous (IV route in flares with significant tissue edema. The following case describes a young woman presenting with lupus enteritis and lupus panniculitis as an initial manifestation of SLE, the utilization of abdominal CT in diagnosis, and current treatment protocols used for lupus enteritis.

    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.

    2004-10-15

    The environmental condition called vacuum is created any time the pressure of a gas is reduced compared to atmospheric pressure. On earth we typically create a vacuum by connecting a pump capable of moving gas to a relatively leak free vessel. Through operation of the gas pump the number of gas molecules per unit volume is decreased within the vessel. As soon as one creates a vacuum natural forces (in this case entropy) work to restore equilibrium pressure; the practical effect of this is that gas molecules attempt to enter the evacuated space by any means possible. It is useful to think of vacuum in terms of a gas at a pressure below atmospheric pressure. In even the best vacuum vessels ever created there are approximately 3,500,000 molecules of gas per cubic meter of volume remaining inside the vessel. The lowest pressure environment known is in interstellar space where there are approximately four molecules of gas per cubic meter. Researchers are currently developing vacuum technology components (pumps, gauges, valves, etc.) using micro electro mechanical systems (MEMS) technology. Miniature vacuum components and systems will open the possibility for significant savings in energy cost and will open the doors to advances in electronics, manufacturing and semiconductor fabrication. In conclusion, an understanding of the basic principles of vacuum technology as presented in this summary is essential for the successful execution of all projects that involve vacuum technology. Using the principles described above, a practitioner of vacuum technology can design a vacuum system that will achieve the project requirements.

  15. Role of FODMAP content in enteral nutrition-associated diarrhea.

    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.

Los avances tecnológicos, el mejor conocimiento de la fisiopatología de la desnutrición, y su participación en la evolución de diferentes entidades clínicas han hecho posible mejorar el cuidado nutricional de nuestros pacientes. La utilización de la NE se ha extendido como una práctica de primera elección en pacientes desnutridos o en riesgo de desnutrición que tienen un intestino minimamente funcionante y no son capaces de cubrir con la alimentación natural o suplementación, el total de sus requerimientos calórico-proteicos. Términos como "alimento-medicamento" o "nutrición órgano o sistema-específica o nutrición patología-específica" han revolucionado el campo de la NE en los últimos 20 años con la eclosión de fórmulas específicamente definidas .La NE ha demostrado ser coste-efectiva en los pacientes desnutridos cuando se establece la indicación con precocidad. La Nutrición Artificial Domiciliaria y Ambulatoria es una técnica regulada administrativamente muy extendida en nuestro país que permite reducir el coste de algunos procesos.

  18. Recent advances in measurement and dietary mitigation of enteric methane emissions in ruminants

    Directory of Open Access Journals (Sweden)

    2016-05-01

    Full Text Available Methane (CH4 emission, which is mainly produced during normal fermentation of feeds by the rumen microorganisms, represents a major contributor to the greenhouse gas (GHG emissions. Several enteric CH4 mitigation technologies have been explored recently. A number of new techniques have also been developed and existing techniques have been improved in order to evaluate CH4 mitigation technologies and prepare an inventory of GHG emissions precisely. The aim of this review is to discuss different CH4 measuring and mitigation technologies, which have been recently developed. Respiration chamber technique is still considered as a gold standard technique due to its greater precision and reproducibility in CH4 measurements. With the adoption of recent recommendations for improving the technique, the SF6 method can be used with a high level of precision similar to the chamber technique. Short-term measurement techniques of CH4 measurements generally invite considerable within- and between animal variations. Among the short-term measuring techniques, Greenfeed and methane hood systems are likely more suitable for evaluation of CH4 mitigation studies, if measurements could be obtained at different times of the day relative to the diurnal cycle of the CH4 production. Carbon dioxide and CH4 ratio, sniffer and other short-term breath analysis techniques are more suitable for on farm screening of large number of animals to generate the data of low CH4 producing animals for genetic selection purposes. Different indirect measuring techniques are also investigated in recent years. Several new dietary CH4 mitigation technologies have been explored, but only a few of them are practical and cost-effective. Future research should be directed towards both the medium- and long-term mitigation strategies, which could be utilized on farms to accomplish substantial reductions of CH4 emissions and to profitably reduce carbon footprint of livestock production systems.

    To communicate the information available by the NADYA-SENPE Working Group from patients on Home Enteral Nutrition (HEN) in our country during the year 2003. The data were collected through a closed questionnaire included in the web site of the Working Group (www.nadya-senpe.com) available only by the authorized users. Variable included were: epidemiological information, the indication to prescribe this treatment, the access path, the specific nutritional formula used, the treatment duration, the complications and hospital readmission related to the nutritional treatment, the follow-up and the quality of life. We register 3,858 patients that belong to twenty-one hospitals. Mean age from those adults 66.2 +/- 18.9 years, and from those younger than 14, 6.0 +/- 4.3 years. Neurological and neoplasic diseases were the diagnostics more frequents (38.9% and 37.4%, respectively). Oral nutrition was the preferential rout used for the enteral nutrition (54.7%) followed by naso-enteral tube (26.6%), and only in 17.6% we used ostomy tubes. Polymeric was the enteral formula mainly utilized (80.1%). The mean time on HEN was 6.6 +/- 4.3 months; the 28.8% of patients stayed in the treatment for less than 3 months, 21.2 % between 3 and 6 months, and 50.0% more than 6 months. Patients were followed mainly by Nutritional Support Unit from the reference hospital (73.1%).

    This article discusses the use of enteral nutrition in the management of stroke. Stroke is a major source of disability, including dysphagia. The clinical manifestation of swallowing difficulties in stroke patients may lead to malnutrition which has implications for health status and clinical outcomes including morbidity, mortality and cost to the health service. The prevalence of malnutrition following an acute stroke could range from 8% to 34%. Therefore, the need to develop and implement the use of enteral nutrition support in stroke patients becomes pertinent. A range of enteral feeding tubes and feeding methods may be used to support stroke patients who are unable to meet their nutritional requirements through oral intake alone, although each of these approaches has its merits and limitations. Based on this review, there is evidence that enteral nutrition support is a useful method of providing nutrition for patients with dysphagia following a stroke in order to enhance their nutritional status and promote their health. However, there are challenges in the use of enteral tube feeding in these patients.

    Objective To evaluate the safety of enteral rehabilitative therapy in rat small bowel transplantation. Methods Forty-eight rat recipients of allogeneic heterotopic small bowel transplantation (SD and Wistar) were randomly divided into 4 groups according to the application or not of enteral rehabilitative therapy and cyclosporine A (CsA). The pathological changes of the graft, IL-2 receptor expression in lamina propria lymphocytes, serum IL-2 concentrations, results of spleen lymphocytes transformation test and the IL-2 secretion capacity were determined and compared. Results Enteral rehabilitative therapy could promote the immune function of the recipient so as to augment the acute rejection. But such effects could be blocked by the commonly used immunosuppressant CsA. Under the immunosuppression of CsA (10 mg*kg-1*d-1, i.m.), application of enteral rehabilitative therapy did not induce or aggravate acute rejection.Conclusion Under effective immunosuppression, application of enteral rehabilitative therapy is safe in rat small bowel transplantation.

Difficulties in feeding patients with dementia may arise at any stage of the disease and may include malnutrition, weight loss, decreased quality of life, among others. Enteral tube feeding by tube may be a way of mitigating the effects, but its benefits are under discussion. Methods: Eight qualitative studies were included: 5 primary sources, 3 systematic literature reviews, published in the 2008-2013 period. Results: Enteral tube feeding in patients with dementia may affect survival/mortality rate (no evidence of benefit, nutritional status (no improvement, functional status and cognitive development (no improvement, aspiration (does not reduce the risk of aspiration, pressure ulcers (no evidence of benefit in ulcers incidence and progression, and quality of life (without hard data in most studies. Conclusion: Evidence on benefits of enteral tube feeding in patients with dementia was not conclusive and may even have the opposite effect. We lack data on the adverse effects of these interventions. Keywords: Palliative care; Dementia; Enteral feeding; Therapeutic use.

    Oral medications are often administered through enteral feeding tubes in patients with complex chronic diseases. It is important to consider possible interactions between drugs and enteral nutrition that might lead to unsuccessful treatment or tube occlusion. These patients become subjects for higher risk of problems and errors such as drug incompatibility with enteral nutrition and inappropriate dosage form selection. It is possible to minimize the risk of tube occlusion and incompatibilities problems by recognizing potential medication errors, selecting the most appropriate drug and dosage form and using appropriate administration techniques. In this context, high-alert medications for patients with chronic diseases deserve special attention. Furthermore, risk exposure should be considered among healthcare professionals and patient caregivers handling hazardous drugs. Therefore, main incompatibility problems between drugs and enteral nutrition have been reviewed, including general recommendations for administration of oral medications through enteral feeding tubes and safe handling of hazardous drugs. Specific recommendations for administration of high-alert medications for patients with chronic diseases are also included.

    This paper, written for the symposium in honour of more than 40 years' contribution to autonomic research by Professor Geoffrey Burnstock, highlights the progress made in understanding the organisation of the enteric nervous system over this time. Forty years ago, the prevailing view was that the neurons within the gut wall were post-ganglionic neurons of parasympathetic pathways. This view was replaced as evidence accrued that the neurons are part of the enteric nervous system and are involved in reflex and integrative activities that can occur even in the absence of neuronal influence from extrinsic sources. Work in Burnstock's laboratory led to the discovery of intrinsic inhibitory neurons with then novel pharmacology of transmission, and precipitated investigation of neuron types in the enteric nervous system. All the types of neurons in the enteric nervous system of the small intestine of the guinea-pig have now been identified in terms of their morphologies, projections, primary neurotransmitters and physiological identification. In this region there are 14 functionally defined neuron types, each with a characteristic combination of morphological, neurochemical and biophysical properties. The nerve circuits underlying effects on motility, blood flow and secretion that are mediated through the enteric nervous system are constructed from these neurons. The circuits for simple motility reflexes are now known, and progress has been made in analysing those involved in local control of blood flow and transmucosal fluid movement in the small intestine.

    We present a case of a 30-year-old postpartum woman who delivered by caesarean section at 34 weeks. On postoperative day 9, she was admitted to our hospital in shock. Emergency abdominal surgery was performed. Massive purulent ascites collected in the abdominal cavity and was associated with intestinal necrosis, which extended from the ascending colon to one-third of the descending colon. The necrotic lesion was excised, and an artificial anus was constructed at the ileum end. A histological finding on the 15th day indicated the possibility of amoebic enteritis, and the patient was started on metronidazole therapy. The diarrhoea improved dramatically after metronidazole treatment was started. The patient was able to walk unassisted on the 45th day and was subsequently discharged. Amoebic enteritis has been thought to be epidemic in developing countries, but today, the incidence of amoebic enteritis as a sexually transmitted disease is increasing in developed countries.

    Clostridium perfringens is one of the major causes of intestinal disease in humans and animals. Its pathogenicity is contributed to by the production of a variety of toxins. In addition, predisposing environmental factors are important for the induction of C. perfringens-associated enteritis as shown by infection models. Environmental contamination, gastric and intestinal pH, intestinal microflora, nutrition, concurrent infections, and medical interventions may influence the intestinal colonization, growth, and toxin production by C. perfringens. Prevention of C. perfringens-associated enteritis may be mediated by the use of feed additives like probiotics, prebiotics, organic acids, essential oils, bacteriophages, lysozymes, bacteriocins, and antimicrobial peptides. Here we summarize and discuss published data on the influence of different environmental predisposing factors and preventive measures. Further research should focus on feed composition and feed additives in order to prevent C. perfringens-associated enteritis.

    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,

    Full Text Available PINs are one of the most popular methods to perform simple and fast user authentication. PIN stands for Personal Identification Number, which may have any number of digits or even letters. Nevertheless, 4-digit PIN is the most common and is used for instance in ATMs or cellular phones. The main advantage of the PIN is that it is easy to remember and fast to enter. There are, however, some drawbacks. One of them - addressed in this paper - is a possibility to steal PIN by a technique called `shoulder surfing'. To avoid such problems a novel method of the PIN entering was proposed. Instead of using a numerical keyboard, the PIN may be entered by eye gazes, which is a hands-free, easy and robust technique. References:

    Early enteral nutrition is an important adjunct in the care of critically ill patients. A double-lumen gastrostomy tube with a duodenal extension has been reported to enable early enteral feeding with simultaneous gastroduodenal decompression. We tested the ability of this device to achieve these goals in critically ill patients. Noncomparative, descriptive case series. Surgical intensive care unit in a university hospital. Fifteen consecutive critically ill patients, who, at the time of laparotomy, were assessed likely to need long-term nutritional support and gastric decompression, underwent tube placement. Mean age was 47 +/- 21 yrs. Mean Acute Physiology and Chronic Health Evaluation (APACHE II) and Therapeutic Intervention Scores were 15 +/- 7.3 (SD) and 29 +/- 10.2, respectively, and the mean Injury Severity Score of 11 trauma patients in the group was 27 +/- 7.4. Correct tube positioning was verified by radiograph or endoscopy. Caloric and protein requirements, nutritional parameters, and problems encountered with the device were recorded. The correlation between the volume of feeding port input and suction port output was noted, and this correlation was considered significant if r2 was > or = .5. Only three (20%) of 15 patients reached full enteral nutritional support via the enteral route. None of these patients achieved this level of nutritional support within the first postoperative week. In 67% of the patients, large quantities of enteral feeding solution appeared in the gastroduodenal suction port effluent. When feeding port input was plotted against effluent volume, a correlation coefficient of > .71 (r2 = > or = .5) was found in 40% of the patients. Other complications included: a) excessive gastroduodenal drainage requiring fluid/electrolyte replacement in eight (53.3%) patients; and b) skin ulceration at the tube entrance site in seven (46.7%) patients. These data do not support the use of this device for early enteral feeding and simultaneous

    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.

    Objective: To investigate the antibacterial activities of green vegetables(pennywort,mint, garlic, parsley and celery) against four common enteric bacteria [Salmonella enterica(ATCC 25957)(S. enterica), Shigella flexneri(ATCC 12022)(S. flexneri),Escherichia coli(ATCC 43889)(E. coli) and Enterobacter cloacae(ATCC 13047)(E. cloacae)] as an alternative medicine for controlling food borne diarrhea disease and the synergistic effect of green vegetables against those bacteria.Methods: Five common vegetables(pennywort, mint, garlic, parsley and celery) were purchased and extracted. The antimicrobial activities of these extracts were tested against four common enteric bacteria(S. enterica, S. flexneri, E. coli and E. cloacae). Ten different concentrations of the extracts(from 640 to 1.25 mg/m L) were prepared and used for the study. The minimal inhibitory concentration(MIC) was determined by the broth dilution method. The antimicrobial activities were assessed by using both well diffusion and disc diffusion methods.Results: Garlic extract showed excellent inhibitory effects on all enteric bacteria. Other plants(parsley, celery, mint and pennywort) were not effective against enteric bacteria.The MIC of garlic against S. flexneri and E. cloacae was 40 mg/m L. The MIC of S. enterica and E. coli were 20 and 10 mg/m L, respectively. The performance of the well diffusion method was better than that of the disc diffusion method with clear and sharp inhibition zones of tested bacteria against plant extracts.Conclusions: Garlic had excellent antimicrobial effects against enteric bacteria and was recommended to be given to patients with gastroenteritis. The other vegetables(pennywort, mint, parsley and celery) showed no inhibitory effects on enteric bacteria but still can be used for its richness in vitamins and fibers. The performance of the well diffusion method was better than that of the disc diffusion method in detecting the antibacterial effects of green vegetables.

    Exclusive enteral nutrition involves the use of a complete liquid diet, with the exclusion of normal dietary components for a defined period of time, as a therapeutic measure to induce remission in active Crohn's disease (CD). This very efficacious approach leads to high rates of remission, especially in children and adolescents newly diagnosed with CD. This intervention also results in mucosal healing, nutritional improvements and enhanced bone health. Whilst several recent studies have provided further elaboration of the roles of exclusive enteral nutrition in the management of CD, other reports have provided new understanding of the mechanisms by which this intervention acts.

    Plant extracts and associated polyphenols are known for their varied health benefits that include antioxidant effects and antimicrobial properties. The increasing consumer demand for cost-effective and natural alternatives to chemically-synthesized antimicrobials and therapeutics that are also sustainable makes the field of phytochemical research rather intriguing and challenging. Human enteric viruses are increasingly recognized worldwide as significant causes of human disease in adults and children, alike. In the absence of available vaccines for the human noroviruses, plant extracts are gaining popularity for the prevention and treatment of viral diseases. Research on plant extracts (particularly polyphenols derived from fruits) for human enteric virus control will be briefly summarized in this article.

    2012-06-01

    Inhibitory gamma-aminobutyric-acid-containing interneurons play important roles in the functions of the neocortex. During rodent development, most neocortical interneurons are generated in the subpallium and migrate tangentially toward the neocortex. They migrate through multiple pathways to enter the neocortex. Failure of interneuron migration through these pathways during development leads to an abnormal distribution and abnormal functions of interneurons in the postnatal brain. Because of recent discoveries regarding the novel origins and migratory pathways of neocortical interneurons, in this article we review the literature on the migratory pathways of interneurons when they enter the neocortex.

  20. Darwinism determines technological survivors

    1996-10-01

    In an industry where new power plant planning and budgeting cycles stretch from one to three years, where a typical new generation product takes from five to 10 years to successfully enter the market and where some plants have a 30- to 50-year economic life, change is an evolutionary process. However, that change, driven by the application of new technologies, is inevitable. Twenty-five years ago, in 1971, gas turbines were perceived to have limited applications and were primarily used for part-time peaking duty. Today, they are the baseload, new power generation technology of choice. Nevertheless, more than 55% of the US`s electricity is still generated by coal-fired steam turbine plants, the technology of choice 25 years ago. Power generation technologies will evolve further, but it`s doubtful there will be any new concepts that are not evident in today`s laboratories. Twenty-five years from now, today`s coal-fires team turbine plants will still provide the majority of the electricity generated in the US. However, new natural gas or syngas-fired combined-cycle plants will make up the majority of the new additions, perhaps as much as 20% of the overall installed capacity in 2021. Still, during the next 25 years, a number of new generation technologies should become economically competitive and enter the market. Technologies moving from today`s demonstrations to widespread applications include: gasification, pressurized fluidized bed combustion, fuel cell hybrid cycles, and solar photovoltaics.

    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.

    Full Text Available Abstract Introduction Systemic lupus erythematosus (SLE is a multisystem disorder that may present with various symptoms. It may involve the gastrointestinal tract in a variety of ways; some of the most well-known ones are transaminitis, lupus mesenteric vasculitis, lupus enteritis and mesenteric vascular leakage. We describe a case of a patient with SLE who presented with a five-month history of diarrhea caused by eosinophilic enteritis. To the best of our knowledge, there are few cases reported in the literature of patients with SLE who initially present with chronic diarrhea due to eosinophilic enteritis. Case presentation A 38-year-old Persian Iranian woman was admitted with a five-month history of diarrhea and abdominal pain. A physical examination showed nothing abnormal. Initially, she had only lymphopenia and mild eosinophilia. No autoimmune or infectious etiology was detected to justify these abnormalities. A thorough evaluation was not helpful in finding the etiology, until she developed a scalp lesion similar to discoid lupus erythematosus. Computed tomography showed small bowel wall thickening. Briefly, she manifested full-blown SLE, and it was revealed that the diarrhea was caused by eosinophilic enteritis. Conclusion Considering SLE in a patient who presents with chronic diarrhea and lymphopenia may be helpful in earlier diagnosis and therapy. This is an original case report of interest to physicians who practice internal medicine, family medicine and gastroenterology.

    The group of standardization and protocols of the Spanish Society of Parenteral and Enteral Nutrition (SENPE) published in 2011 a consensus document SENPE/SEGHNP/ANECIPN/SECP on enteral access for paediatric nutritional support. Along the lines of this document, we have developed another document on adult patients to homogenize the clinical practice and improve the quality of care in enteral access in this age group. The working group included health professionals (nurses, dietitians and doctor) with extensive experience in enteral nutrition and access. We tried to find scientific evidence through a literature review and we used the criteria of the Agency for Health-care Research and Quality (AHRQ) to classify the evidence (Grade of Recommendation A, B or C). Later the document was reviewed by external experts to the group and requested the endorsement of the Scientific and Educational Committee (CCE) and the group of home artificial nutrition (NADYA) of the SENPE. The full text will be published as a monograph number in this journal.

    Diarrhea is a major clinical problem affecting foals up to 3 months of age. The aim of this study was to identify enteric microorganisms involved in monoinfections and coinfections and the associated virulence factors in healthy and diarrheic foals. Diarrheic (D) (n = 56) and nondiarrheic (ND) foals (n = 60) up to three months of age were studied. Fecal samples were analyzed for identification of infectious agents (microbiological culturing, molecular techniques, and microscopic analyses). Escherichia coli fimH (30% versus 25%), Salmonella spp. (25% versus 7%), Strongyloides westeri (25% versus 25%), Clostridium perfringens type A (21% versus 10%), E. coli ag43 (20% versus 35%), Strongylus (11% versus 18%), and vapA-positive Rhodococcus equi (5% versus 2%) were the most frequent enteric pathogens detected in D and ND foals, respectively. The frequency of toxin A-positive C. perfringens was significantly increased in the D (p = 0.033) compared with the ND animals. R. equi strains harboring virulent plasmids were also identified (VapA 85-kb type I and VapA 87-kb type I) in D and ND foals. Coinfections were observed in 46% of the D and 33% of the ND foals. Our results demonstrate the great diversity of enteric pathogens, virulence factors, and coinfections involved in enteric infections of foals.

    2014-01-01

    The objective of this study was to investigate the effect of feed restriction on the intestinal ecosystem and on the pathogenesis of experimental necrotic enteritis in broiler chicks. To induce subclinical necrotic enteritis, an experimental challenge model using a specific diet formulation, Gumboro vaccination, oral inoculation of broilers with a 10-fold dose of attenuated anticoccidial vaccine and multiple oral inoculations with a specific strain of Clostridium perfringens was adopted. Two hundred and forty 1-day-old Cobb 500 broilers were randomly allocated to four groups: feed restricted, challenged, both feed restricted and challenged, and negative control. At 21, 22, 23 and 24 days of age, the intestines, gizzard and liver were collected from 15 birds in each group and scored for gross lesions. The intestinal digesta was collected for pH and viscosity determination. One caecum from each bird was taken for microbiological analysis. The application of feed restriction in birds challenged with C. perfringens reduced the necrotic enteritis lesion score significantly (P ≤ 0.05) and feed restriction significantly reduced (P ≤ 0.05) pH in the small intestine, the viscosity of the jejunum digesta as well as the C. perfringens counts in the caeca compared with the controls. In conclusion, feed restriction of broilers has a positive effect on the intestinal ecosystem and a significant protective effect against necrotic enteritis in the subclinical experimental model.

    Full Text Available Diarrhea is a major clinical problem affecting foals up to 3 months of age. The aim of this study was to identify enteric microorganisms involved in monoinfections and coinfections and the associated virulence factors in healthy and diarrheic foals. Diarrheic (D (n=56 and nondiarrheic (ND foals (n=60 up to three months of age were studied. Fecal samples were analyzed for identification of infectious agents (microbiological culturing, molecular techniques, and microscopic analyses. Escherichia coli fimH (30% versus 25%, Salmonella spp. (25% versus 7%, Strongyloides westeri (25% versus 25%, Clostridium perfringens type A (21% versus 10%, E. coli ag43 (20% versus 35%, Strongylus (11% versus 18%, and vapA-positive Rhodococcus equi (5% versus 2% were the most frequent enteric pathogens detected in D and ND foals, respectively. The frequency of toxin A-positive C. perfringens was significantly increased in the D (p=0.033 compared with the ND animals. R. equi strains harboring virulent plasmids were also identified (VapA 85-kb type I and VapA 87-kb type I in D and ND foals. Coinfections were observed in 46% of the D and 33% of the ND foals. Our results demonstrate the great diversity of enteric pathogens, virulence factors, and coinfections involved in enteric infections of foals.

    2012-01-01

    In a NICU early enteral feeding is usually possible only when the newborn clinical conditions permit it. Because of the frequent need of umbilical/central catheters, they usually start with parenteral feeding and/or with minimal enteral feeding (trophic feeding). This kind of management is even more frequent in VLBWIs, in which the risk of NEC is very high. In this work we describe a model of early enteral exclusive feeding (EEEF) based on the use of banking human milk followed by mother milk. In the Centre of Neonatology of Trento, as in other Centers, the newborns weighing less than 750g or with a GE 26 weeks define a group in which we find critical neonates, who can not be treated with enteral feeding, and neonates whose clinical conditions permit EEEF. In particular, in a period of 16 years (1994-2009) in Trento, 308 newborns weighing 750-1249 g and GE > than 26 weeks were admitted. The 90,9 % has been treated with prenatal steroids, the 91,9 % was inborn, the 96,1% survived. In the 59,1 % of the cases (175) we gave EEEF. We could continue with a complete EEEF in the 40,2 % of the total (119 cases). The characteristics of these neonates and our centre management, based mainly on early use of banking human milk and mother milk, are detailed described.

    One of the clearest indications for enteral nutrition is made up by patients who underwent treatment for orofacial pathology. In this way, we have reviewed retrospectively, 321 clinical histories of patients who underwent treatment (orofacial surgery), dividing these according to the pathology; neoplasia or non-neoplasia (173/148), with enteral nutrition 24 hours after the intervention. Data are collected with regard to the tolerance (vomiting, diarrhea), time needed to reach 1.500 kcal/day, need of parenteral nutritional support, transferrin, prealbumin, and albumin quantification at the start of the nutritional therapy, as well as the total duration there of. Globally, the good enteric tolerance of both groups of patients is noted, despite the fact that the oncological group showed a greater degree of protein malnutrition (statistically significant). As for the total duration of the nutrition, this is greater in the neoplasias, probably due to a more aggressive surgery. The results obtained permit modification of the basic enteral nutrition protocol (reduction of the time used to reach the maximum volume), as well as stressing the preoperative and postoperative regulated nutritional evaluation.

    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

    Full Text Available Campylobacter es un importante agente causante de enfermedad en el ser humano en nuestro medio. Los casos de bacteriemia ocurren principalmente en pacientes inmunosuprimidos y son debidos frecuentemente a C. fetus. Sin embargo la bacteriemia es un episodio que también se ha observado en pacientes con enteritis por C. jejuni. Referimos dos pacientes con enteritis grave y bacteriemia, ambos con enfermedades concomitantes compatibles con inmunodepresión: uno con síndrome nefrótico de larga data y otro con hepatopatía crónica con cirrosis. Destacamos que los dos casos presentaron hematemesis y uno de ellos, enterorragia. Sugerimos prestar atención a la coloración de Gram durante el subcultivo de los caldos con hemocultivos, en busca de formas características de esta especie, y en ese caso emplear medios de cultivo en microaerofilia a 37 y 42 °C.Campylobacter is an important agent of illness in human beings.

    2012-01-01

    This is a case report of a patient who presented to the Aga Khan University Hospital with generalized abdominal lymphadenopathy and high-grade fever. Due to ambiguous clinical findings, which were suggestive of either abdominal tuberculosis, or a lymphoma, the patient was started on empirical anti-tuberculous treatment due to the endemicity of tuberculosis in this region. The blood culture reports, however, were reported to grow colonies of Salmonellaparatyphi A; thus the diagnosis of the patient was changed to enteric fever, and the patient improved on the subsequently started therapy of ceftriaxone 2 000 mg bid. To the best of our knowledge, this is the first reported case of a patient suffering from enteric fever whose primary clinical findings were abdominal lymphadenopathy and fever.

  19. Entering adulthood in a recession tempers later narcissism.

    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.

  20. Scheme for Entering Binary Data Into a Quantum Computer

    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.

    2016-06-01

    Enteric fever (typhoid and paratyphoid) remains a threat to British troops overseas and causes significant morbidity and mortality. We report the case of a soldier who developed typhoid despite appropriate vaccination and field hygiene measures, which began 23 days after returning from a deployment in Sierra Leone. The incubation period was longer than average, symptoms started 2 days after stopping doxycycline for malaria chemoprophylaxis and initial blood cultures were negative. The Salmonella enterica serovar Typhi eventually isolated was resistant to amoxicillin, co-amoxiclav, co-trimoxazole and nalidixic acid and had reduced susceptibility to ciprofloxacin. He was successfully treated with ceftriaxone followed by azithromycin, but 1 month later he remained fatigued and unable to work. The clinical and laboratory features of enteric fever are non-specific and the diagnosis should be considered in troops returning from an endemic area with a febrile illness. Multiple blood cultures and referral to a specialist unit may be required.

    We treated 17 patients with severe small-bowel radiation enteritis surgically. Fourteen patients were female. Gynecologic malignant lesions (cervical, ovarian, and endometrial) were the most frequent sites of the primary tumors for which radiation was given. Thirteen patients had bowel obstruction, and the remainder had enterovaginal fistulae. Intestinal bypass, rather than resection, was the preferred approach in the treatment of these patients, and was used in 11 cases. Successful palliation was provided in nine patients, with minimal morbidity and no operative deaths. Follow-up at eight to 60 months has shown no further sequelae of radiation injury or of blind loop syndrome. This supports the relative safety of intestinal bypass for the surgical management of small-bowel radiation enteritis.

    Actions of ANG II on electrical and synaptic behavior of enteric neurons in the guinea pig small intestine were studied. Exposure to ANG II depolarized the membrane potential and elevated neuronal excitability. The number of responding neurons was small, with responses to ANG II in 32% of submucosal neurons and 25% of myenteric neurons. Hyperpolarizing responses were evoked by ANG II in 45% of the neurons. The hyperpolarizing responses were suppressed by alpha2-noradrenergic receptor antagonists, which suggested that the hyperpolarizing responses reflected stimulation of norepinephrine release from sympathetic neurons. Exposure to ANG II enhanced the amplitude and prolonged the duration of noradrenergic inhibitory postsynaptic potentials and suppressed the amplitude of both fast and slow excitatory postsynaptic potentials. The selective ANG II(1) receptor (AT1R) antagonists, ZD-7115 and losartan, but not a selective AT2R antagonist (PD-123319), suppressed the actions of ANG II. Western blot analysis and RT-PCR confirmed expression of AT1R protein and the mRNA transcript for the AT1R in the enteric nervous system. No expression of AT2R protein or mRNA was found. Immunoreactivity for AT1R was expressed by the majority of neurons in the gastric antrum and small and large intestine. AT1R immunoreactivity was coexpressed with calbindin, choline acetyltransferase, calretinin, neuropeptide Y, and nitric oxide synthase in subpopulations of neurons. The results suggest that formation of ANG II might have paracrine-like actions in the enteric nervous system, which include alterations in neuronal excitability and facilitated release of norepinephrine from sympathetic postganglionic axons. The enhanced presence of norepinephrine is expected to suppress fast and slow excitatory neurotransmission in the enteric microcircuits and to suppress neurogenic mucosal secretion.

  6. The role of carbohydrates in infection strategies of enteric pathogens.

    2015-03-01

    Enteric pathogens cause considerable public health concerns worldwide including tropical regions. Here, we review the roles of carbohydrates in the infection strategies of various enteric pathogens including viruses, bacteria and protozoa, which infect the epithelial lining of the human and animal intestine. At host cell entry, enteric viruses, including norovirus, recognize mainly histo-blood group antigens. At the initial step of bacterial infections, carbohydrates also function as receptors for attachment. Here, we describe the function of carbohydrates in infection by Salmonella enterica and several bacterial species that produce a variety of fimbrial adhesions. During invasion by enteropathogenic protozoa, apicomplexan parasites utilize sialic acids or sulfated glycans. Carbohydrates serve as receptors for infection by these microbes; however, their usage of carbohydrates varies depending on the microbe. On the surface of the mucosal tissues of the gastrointestinal tract, various carbohydrate moieties are present and play a crucial role in infection, representing the site of infection or route of access for most microbes. During the infection and/or invasion process of the microbes, carbohydrates function as receptors for various microbes, but they can also function as a barrier to infection. One approach to develop effective prophylactic and therapeutic antimicrobial agents is to modify the drug structure. Another approach is to modify the mode of inhibition of infection depending on the individual pathogen by using and mimicking the interactions with carbohydrates. In addition, similarities in mode of infection may also be utilized. Our findings will be useful in the development of new drugs for the treatment of enteric pathogens.

    Lawrence, G; Walker, P D

    1976-01-17

    It is suggested that enteritis necroticans occurs in the people of the Highlands of Papua New Guinea because they have low levels of digestive proteases in the intestinal lumen. These low protease levels are the result of a low-protein diet and the presence of heat-stable trypsin inhibitors in sweet potatato, the dietary staple. Low proteolytic activity allows the B toxin of Clostridium welchii type C, which is extremely susceptible to proteolysis, to initiate the disease.

    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.

  14. Seasonality in human zoonotic enteric diseases: a systematic review.

    Directory of Open Access Journals (Sweden)

    Aparna Lal

    Full Text Available BACKGROUND: Although seasonality is a defining characteristic of many infectious diseases, few studies have described and compared seasonal patterns across diseases globally, impeding our understanding of putative mechanisms. Here, we review seasonal patterns across five enteric zoonotic diseases: campylobacteriosis, salmonellosis, vero-cytotoxigenic Escherichia coli (VTEC, cryptosporidiosis and giardiasis in the context of two primary drivers of seasonality: (i environmental effects on pathogen occurrence and pathogen-host associations and (ii population characteristics/behaviour. METHODOLOGY/PRINCIPAL FINDINGS: We systematically reviewed published literature from 1960-2010, resulting in the review of 86 studies across the five diseases. The Gini coefficient compared temporal variations in incidence across diseases and the monthly seasonality index characterised timing of seasonal peaks. Consistent seasonal patterns across transnational boundaries, albeit with regional variations was observed. The bacterial diseases all had a distinct summer peak, with identical Gini values for campylobacteriosis and salmonellosis (0.22 and a higher index for VTEC (Gini  0.36. Cryptosporidiosis displayed a bi-modal peak with spring and summer highs and the most marked temporal variation (Gini = 0.39. Giardiasis showed a relatively small summer increase and was the least variable (Gini = 0.18. CONCLUSIONS/SIGNIFICANCE: Seasonal variation in enteric zoonotic diseases is ubiquitous, with regional variations highlighting complex environment-pathogen-host interactions. Results suggest that proximal environmental influences and host population dynamics, together with distal, longer-term climatic variability could have important direct and indirect consequences for future enteric disease risk. Additional understanding of the concerted influence of these factors on disease patterns may improve assessment and prediction of enteric disease burden in temperate

  15. Enteral Nutrition for Feeding Severely Underfed Patients with Anorexia Nervosa

    Directory of Open Access Journals (Sweden)

    Maria Gabriella Gentile

    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.

  19. Public hospitals: the legal obstacles of entering into joint ventures.

    Science.gov (United States)

    Miller, J N

    1986-03-01

    Public hospitals, as public entities, are limited in many of their activities by state constitutions and statutes. One area where activity can be particularly limited is the joint venture. Constitutional and statutory limitations can influence several aspects of the joint venture: scope of activities, geographic boundaries, authority to enter into joint ventures, gift of public funds prohibition, and stock ownership. Therefore, public hospitals must be aware of possible legal obstacles and carefully consider their options.

    To describe the results of the home enteral nutrition (HEN) registry of the NADYA-SENPE group in 2010. We retrieved the data of the patients recorded from January 1st to December 31st 2010. We registered 6,591 patients (51% males) with 6,688 episodes of HEN, from 32 hospitals. Mean age in those younger than 14 yr (4%) was 1 ± 2 yrs (m ± SD) and 69,9 ± 17,8 yrs in those older than 14 yr. The length of HEN was longer than 2 yrs in 76% of the patients. The most frequent underlying disease was neurological disorders 42%, followed by cancer 28% (mostly head and neck cancer 18%). We had information related to the enteral access route in only 626 cases (9,4%), 51% of them used nasogastric tubes, 27% gastrostomies, 10% oral route and 3% jejunostomies. Only 251 episodes were closed during the year, mostly due to patient death 57% and progress to oral diet 14%. The activity level was limited in 29% of the patients and 39% of them were bed- or chairridden. Total or partial help was needed by 68% of the patients. The hospitals and the private pharmacies delivered the enteral formula in 63% and 34% of the cases, respectively. The hospitals and the primary care centres delivered the disposables in 83% and 16% of the cases, respectively. The results of the 2010 HEN registry are similar to those published in previous years regarding the number and characteristics of the patients. We continue finding problems in the entrance of data referred to the enteral access route and the closing of the episodes.

  8. 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.

    2014-06-01

    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

    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

    An outbreak of enteric listeriosis in steers that were fed spoiled silage is reported. The outbreak started 2 days after ~200 animals in a single paddock were given a supplement of spoiled silage. Forty animals (20%) were affected, and 13 (6.5%) died over a period of 10 days. Affected animals were recumbent, depressed, and had diarrhea with mucus and fibrin. Gross and microscopic findings in 3 animals that were subjected to autopsy included excess peritoneal fluid, congestion and edema of abomasum, suppurative enteritis and colitis, and suppurative mesenteric lymphadenitis. Two strains of Listeria monocytogenes were isolated, one of serotype 1/2c from the gallbladder and one of serotype 1/2b from the spoiled silage. Listeria monocytogenes was detected in the mesenteric lymph nodes and intestinal wall of 1 animal by immunohistochemistry (IHC). Clinical history and signs, gross and microscopic findings, bacterial isolation, and IHC results confirmed a diagnosis of enteric listeriosis. The source of infection was likely the spoiled silage.

  12. Ion channel expression in the developing enteric nervous system.

    Directory of Open Access Journals (Sweden)

    Full Text Available The enteric nervous system arises from neural crest-derived cells (ENCCs that migrate caudally along the embryonic gut. The expression of ion channels by ENCCs in embryonic mice was investigated using a PCR-based array, RT-PCR and immunohistochemistry. Many ion channels, including chloride, calcium, potassium and sodium channels were already expressed by ENCCs at E11.5. There was an increase in the expression of numerous ion channel genes between E11.5 and E14.5, which coincides with ENCC migration and the first extension of neurites by enteric neurons. Previous studies have shown that a variety of ion channels regulates neurite extension and migration of many cell types. Pharmacological inhibition of a range of chloride or calcium channels had no effect on ENCC migration in cultured explants or neuritogenesis in vitro. The non-selective potassium channel inhibitors, TEA and 4-AP, retarded ENCC migration and neuritogenesis, but only at concentrations that also resulted in cell death. In summary, a large range of ion channels is expressed while ENCCs are colonizing the gut, but we found no evidence that ENCC migration or neuritogenesis requires chloride, calcium or potassium channel activity. Many of the ion channels are likely to be involved in the development of electrical excitability of enteric neurons.

    Enteral nutrition (EN) misconnections have been identified as a serious and potential deadly problem. An international effort led by EN industry leaders has developed a small-bore enteral connector (ENFit) that in theory will reduce the frequency of misconnections. Despite the potential benefit of preventing misconnections, the full impact of adoption of the ENFit connector is unknown. To assess the impact of transitioning to ENFit on our home EN (HEN) patients, the current study evaluated gravity feeding comparing 2 proposed small-bore connectors to the legacy (current connector) using various commercial formulas. Six commonly used enteral formulas in our facility with varying density and viscosity were tested in triplicate. Forty milliliters of formula was poured into a syringe connected to an ENFit or legacy (current) feeding connector attached to varying French size tubes. The time it took formula to flow through the connectors was recorded, and the test was repeated in triplicate. All formulas took significantly longer to flow through the first ENFit connector compared with the legacy connector ( P gravity flow, as ENFit tubes are being developed and adopted.

  15. Vaccines against enteric infections for the developing world

    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

    It is the position of the American College of Clinical Pharmacy (ACCP) that formal postgraduate residency training, or equivalent experience, is required to enter direct patient care practice. Therefore, it is important to align professional degree educational outcomes with the knowledge, skills, and attitudes needed to enter residency training. This position statement addresses the outcomes necessary in the professional degree program curriculum to ensure the ability of pharmacy graduates to transition effectively into postgraduate year one residency training. Five key outcome areas are identified: communication, direct patient care, professionalism, research, and practice management. The position statement examines how performance in each of the five outcome areas should be addressed by professional degree programs. The ACCP believes that for the student to achieve the clinical proficiency necessary to enter residency training, the professional degree program should emphasize, assess, and provide adequate opportunities for students to practice: communication with patients, caregivers, and members of the health care team in direct patient care environments; provision of direct patient care in a wide variety of practice settings, especially those involving patient-centered, team-based care; professionalism under the supervision and guidance of faculty and preceptors who model and teach the traits of a health care professional; application of principles of research that engender an appreciation for the role of research and scholarship in one's professional development; and application of practice management, including documentation of direct patient care activities that affect drug-related outcomes.

    Rood, Julian I; Keyburn, Anthony L; Moore, Robert J

    2016-06-01

    Clostridium perfringens is the primary causative agent of avian necrotic enteritis. Our understanding of the pathogenesis of this economically important disease has been enhanced by the discovery of C. perfringens NetB toxin, which belongs to the α-haemolysin family of β-pore-forming toxins. In a chicken disease model, the analysis of an isogenic set of strains comprising the wild type, a netB mutant, and its complemented derivative, fulfilled molecular Koch's postulates and revealed that NetB was essential for disease. These results were consistent with epidemiological surveys, which generally found that there was a higher prevalence of netB carriage in C. perfringens isolates from diseased poultry compared to healthy birds. The netB gene has been shown to be located on large conjugative plasmids that are closely related to other toxin plasmids from C. perfringens, which has potential implications for the epidemiology of necrotic enteritis infections. The crystal structures of both monomeric NetB and the heptameric NetB pore have been determined, the latter revealed a central pore diameter of approximately 26 Å. Finally, it has been shown that vaccine preparations that include NetB can protect chickens against disease and a series of single amino acid substitution derivatives of NetB that have potential value for vaccine formulations have been isolated and analysed. It is likely that NetB will be an important antigen to include in an effective, commercially viable, necrotic enteritis vaccine.

    To examine the prevalence of physical health problems among youth entering residential treatment. The sample included 1744 youth (mean age: 14.6 ± 1.8 years) entering a large residential treatment program between 2000 and 2010. Youth received an intake medical evaluation, including a review of available records, detailed medical history, and physical examination. Medical conditions present at the time of the evaluation were recorded by the examining physician and later coded by the research team. Only diagnoses recognized by the International Classification of Diseases, 10th Revision, were included in the analyses. To maintain the focus on physical health problems, behavioral and emotional disorders listed in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision were excluded. Obesity, acne, and allergies were also excluded. Approximately one-third (33.7%) of youth had a physical health diagnosis at the time of intake. Asthma was the most prevalent condition diagnosed (15.3% of the sample). Girls were significantly more likely to have a diagnosis than were boys (37.1% vs 31.5%). Age was not associated with diagnostic status. Rates of physical health conditions differed significantly by ethnicity: black (36.4%) and white (35.4%) youth had the highest rates, and Hispanic youth (23.2%) had the lowest. Youth who enter residential treatment have high rates of physical health conditions. These problems could complicate mental health treatment and should be considered in multidisciplinary treatment planning.

    Eosinophilic enteritis is a rather rare condition characterized by infiltration of the gastrointestinal tract by eosinophils; as a casue of acute abdomen it is really exceptional. The etiology is unclear and its description in the literature is sparse, but associations have been made with collagen vascular disease, inflammatory bowel disease, food allergy and parasitic infections as it was confirmed in one of our pathologic studies. From 1997 to 2011 six cases of eosinophilic enteritis that involved a small bowel segment were diagnosed. A partial resection by an irreversible necrosis was necessary in three of them; in the other three only a biopsy was necessary due to the inflammatory aspect of the affected loop causing the acute abdomen. Eosinophilic enteritis can originate acute abdomen processes where an urgent surgical treatment is necessary. The intraoperative aspect can be from a segment of small bowel with inflammatory signs up to a completely irrecoverable loop, where removing of the affected segment is the correct treatment, which can be done laparoscopically.

  1. Ipilimumab-Induced Enteritis without Colitis: A New Challenge

    Directory of Open Access Journals (Sweden)

    Marcus Messmer

    2016-11-01

    Full Text Available Introduction: Ipilimumab is an immune checkpoint inhibitor targeting cytotoxic T-lymphocyte associated antigen 4 (CTLA4, approved to treat metastatic melanoma. It was the first therapy shown to prolong survival in a large, randomized clinical trial. However, immune-related adverse events are common and can be severe. Enterocolitis is a common adverse event with ipilimumab, but enteritis without colitis has not been previously described. Case Report: An 83-year-old man presented to our hospital with grade 3 diarrhea for 5 days. One month prior, he had started treatment with ipilimumab for metastatic melanoma. On presentation, he was found to have severe electrolyte disturbances, including hyponatremia, hypokalemia, and acute kidney injury. Causes of infectious diarrhea were excluded, and he was treated with corticosteroids for presumed ipilimumab-associated enterocolitis. However, colonoscopy revealed normal mucosa, both grossly and on pathology of random biopsies. Steroids were weaned but his symptoms recurred. He then underwent upper endoscopy with enteroscopy. Biopsy of the duodenum was notable for acute inflammation, villous blunting, and other changes consistent with ipilimumab-associated injury. He was restarted on high-dose steroids and his symptoms resolved. Discussion: Ipilimumab-induced enteritis is a serious and potentially life-threatening immune related adverse event that warrants prompt recognition and aggressive management. As in cases of ipilimumab-associated enterocolitis, steroids are an effective therapy. Enteritis without colitis should be suspected in patients on ipilimumab who present with severe diarrhea but have a normal colonoscopy.

    Rosacea is a chronic inflammatory dermatosis affecting the face and eyes. An association between systemic comorbidities and rosacea has been reported, but the link to enteral microbiota is uncertain. We aimed to investigate the link between rosacea and enteral microbiota. A cross-sectional study was performed in a sample of Korean women who participated in a health check-up programme at the Kangbuk Samsung Hospital Health Screening Center between 23 June 2014 and 5 September 2014. The gut microbiome was evaluated by 16S rRNA gene and metagenome sequence analyses. A total of 12 rosacea patients and 251 controls were enrolled. We identified links between rosacea and several changes in gut microbiota: reduced abundance of Peptococcaceae family unknown genus, Methanobrevibacter (genus), Slackia (genus), Coprobacillus (genus), Citrobacter (genus), and Desulfovibrio (genus), and increased abundance of Acidaminococcus (genus), Megasphaera (genus), and Lactobacillales order unknown family unknown genus. A link between rosacea and enteral microbiota was observed in this metagenomic study. A large and elaborate study is needed to confirm these findings and to elucidate the mechanisms involved. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  3. Bacteriophages as indicators of faecal pollution and enteric ...

    Science.gov (United States)

    Bacteriophages are an attractive alternative to fecal indicator bacteria (FIB), particularly as surrogates of enteric virus fate and transport due to their closer morphological and biological properties compared to FIB. Based on a meta-analysis of published data, we summarize concentrations of coliphages (F+ and somatic), Bacteroides spp. and enterococci bacteriophages (phages) in human waste, non-human waste, fresh and marine waters as well as removal through wastewater treatment processes. We also provide comparisons with FIB and enteric viruses whenever possible. Lastly, we examine fate and transport characteristics in the environment and provide an overview of the methods available for detection and enumeration of bacteriophages. In summary, concentrations of FIB bacteriophages in various sources were consistently lower than FIB, but more reflective of infectious enteric virus levels. Our investigation supports use of bacteriophages as viral surrogates especially for wastewater treatment processes, while additional research is needed to clarify their utility as indicators of viral fate and transport in the ambient water. Describes concentrations and removal through environmental and engineered systems of bacteriophages, fecal indicator bacteria and viral pathogens.

    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.

    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.

    Experimental evidence indicates that chronic mechanical sub-occlusion of the intestine may damage the enteric nervous system (ENS), although data in humans are lacking. We here describe the first case of enteric degenerative neuropathy related to a congenital obstruction of the gut. A 3-year and 9-mo old girl began to complain of vomiting, abdominal distension, constipation with air-fluid levels at plane abdominal radiology.Her subsequent medical history was characterized by 3 operations: the first showed dilated duodeno-jejunal loops in the absence of occlusive lesions; the second (2 years later) was performed to obtain full-thickness biopsies of the dilated intestinal loops and revealed hyperganglionosis at histopathology; the third (9 years after the hyperganglionosis was identified) disclosed a Ladd's band which was removed and the associated gut malrotation was corrected. Repeated intraoperative full-thickness biopsies showed enteric degenerative neuropathy along with reduced interstitial cells of Cajal network in dilated loops above the obstruction and a normal neuromuscular layer below the Ladd's band. One year after the latest surgery the patient tolerated oral feeding and did well, suggesting that congenital (partial) mechanical obstruction of the small bowel in humans can evoke progressive adaptive changes of the ENS which are similar to those found in animal models of intestinal mechanical occlusion. Such ENS changes mimic neuronal abnormalities observed in intestinal pseudoobstruction.

    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.

    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.

    Awareness of antibiotics in wastewaters and aquatic ecosystems is growing as investigations into alternate pollutants increase and analytical techniques for detecting these chemicals improve. The presence of three antibiotics (ciprofloxacin, norfloxacin and cephalexin) was evaluated in both sewage effluent and environmental waters downstream from a sewage discharge. Bacteria cultured from the sewage bioreactor and receiving waters were tested for resistance against six antibiotics (ciprofloxacin, tetracycline, ampicillin, trimethoprim, erythromycin and trimethoprim/sulphamethoxazole) and effects of short term exposure (24 h) to antibiotics on bacterial denitrification rates were examined. Antibiotics were detected entering the sewage treatment plant with varying levels of removal during the treatment process. Antibiotics were also detected in effluent entering receiving waters and detectable 500 m from the source. Among the bacteria cultured from the sewage bioreactor, resistance was displayed against all six antibiotics tested and bacteria cultured from receiving waters were resistant against two of the antibiotics tested. Rates of denitrification were observed to decrease in response to some antibiotics and not to others, though this was only observed at concentrations exceeding those likely to be found in the environment. Findings from this preliminary research have indicated that antibiotics are entering our aquatic systems and pose a potential threat to ecosystem function and potentially human health.

    Radiation therapy has been widely used as one of several therapies for malignant disease of the lower abdomen. However, radiation enteritis was a severe side effect, and it was very difficult to treat and care. We report the cases of radiation enteritis that we encountered, especially ileum injuries. There were 27 regions in 23 patients: 10 obstipation, 8 fistula 6 perforation, 2 obstipation and perforation, 1 obstipation and fistula to urinary tract, and 1 perforation and bleeding of sigmoid colon. We treated these by combined bypass, resection of the bowels, external fistula, and others. Radiation enteritis is considered a progressive and irreversible disease, and many patients would experience recurrences over their lifetime, and in some cases would need multiple operations. The leakage and the short bowel after resection were severe problems, and in addition, we found that the abdominal wall was one of the difficult problems to treat and care, such as many external fistula and hardening of abdominal wall after polysurgery and radiation therapy.

    Full Text Available Market environment is currently characterised by a constant dynamic development and changing conditions. The wine sector in the Czech Republic has passed and still passes through a number of changes which affect the decisions of business entities that are considering whether to enter the industry or not. The importance of strategic management is on the rise in this area as well as the significance of a company strategies creation which give the company the instructions how to use their distinctive ability and transform it into a competitive advantage. With regard to the distribution of market shares of each of the companies in the market, it is considered that the market will enter two different size firms, i.e. company A and B, in which the fundamental assumptions have been chosen so that they simulate two extreme examples of enterprises that might emerge in the market. The two chosen types of businesses are proposed recommendations focused on the most effective entry with the use of a methodological tool – GE Matrix (General Electric. For the micro-enterprise (company B it was a careful entry with minimising the entry investment, differentiation of production and subsequent gradual increase of the market share. For medium-sized enterprise (company A it means the need of high investments, primarily to the purchase of technology and marketing.

  13. Natural Bioactive Food Components for Improving Enteral Tube Feeding Tolerance in Adult Patient Populations.

    Kuchnia, Adam J; Conlon, Beth; Greenberg, Norman

    2017-08-01

    Tube feeding (TF) is the most common form of nutrition support. In recent years, TF administration has increased among patient populations within and outside hospital settings, in part due to greater insurance coverage, reduced use of parenteral nutrition, and improved formularies suitable for sole source nutrition. With increasing life expectancy and improved access to TFs, the number of adults dependent on enteral nutrition is expected to grow. However, enteral TF intolerance (ETFI) is the most common complication of TFs, typically presenting with at least 1 adverse gastrointestinal event, including nausea, diarrhea, and constipation. ETFI often leads to reductions in TF volume with associated energy and protein deficits. Potentially ensuing malnutrition is a major public health concern due its effects on increased risk of morbidity and mortality, infections, prolonged hospital length of stay, and higher healthcare costs. As such, there is a need for intervention strategies to prevent and reduce ETFI. Incorporating whole foods with bioactive properties is a promising strategy. Emerging research has elucidated bioactive properties of whole foods with specific benefits for the prevention and management of adverse gastrointestinal events commonly associated with TFs. However, lack of evidence-based recommendations and technological challenges have limited the use of such foods in commercial TF formulas. This review addresses research gaps by discussing 5 whole foods (rhubarb, banana, curcumin, peppermint oil, and ginger) with bioactive attributes identified through literature searches and clinical experience as having substantial scientific rationale to consider their application for ETFI in adult populations.

    Liu, Fang; Basit, Abdul W

    2010-10-15

    The in vivo performance of a novel enteric double-coating technology designed to accelerate release in the proximal small intestine of humans was investigated. Tablet cores were coated with a double layer formulation consisting of an inner layer of EUDRAGIT L 30 D-55 neutralised to pH 6.0 in the presence of 10% citric acid, and an outer layer of standard EUDRAGIT L 30 D-55. A conventional single coating of EUDRAGIT L 30 D-55 was also applied to tablets for comparison purposes, with the identical coating formulation and thickness (5mg/cm(2)) as the outer layer of the double coating. Eight fasted volunteers received the double-coated and single-coated tablets in a two-way crossover study. The formulations were radiolabelled and followed by gamma scintigraphy; the disintegration times and positions were recorded. After leaving the stomach, tablets coated with the single-coating formulation showed a significant time delay before disintegration occurred in the mid to distal small intestine, with a mean disintegration time of 66 ± 22 min post gastric emptying. The double-coated tablets disintegrated earlier at 28 ± 6min post gastric emptying with consistent disintegration in the proximal small intestine. The accelerated in vivo disintegration of the double-coating system can overcome the limitations of conventional enteric coatings.

    Background Early enteral feeding (EF) may result in fever, elevated white blood cell count, increased serum levels of liver enzymes, and diarrhea. We name the complications "enteral refeeding syndrome", as a subtype of refeeding syndrome, because they are likely to result from long-term lack of lumen nutrition. The aim of this study was to investigate the characteristics of enteral refeeding syndrome after long-term total parenteral nutrition(TPN), and the solution for the disease.Methods We collected the clinical data of 100 patients with gastrointestinal fistula, who were cured from Apirl2001 to July 2002. Their fasting time, daily stool frequency, body temperature, heart rate, respiratory rate, levels of transaminases, alkaline phosphatase (AKP), and γ-glutamylcyclotransferase (γ-GT), white blood cell count,and systemic inflammatory reaction syndrome (SIRS) score were recorded before and 1, 3, 5, 10, and 15 days after EF. Student's t test and analysis of variance were used to analyze the data.Results Of the 100 patients, 56 were cured after selective resection of intestinal fistula, 15 were cured by emergency operation, and 29 recovered spontaneously. The levels of AKP and γ-GT increased significantly on the 3rd day after EF [On the 3rd day after EF, (243.0± 121.6) U/L and (177.2± 109.9) U/L vs. before EF (181.5± 127.5) U/L and (118.4±94.2) U/L, P<0.05], and decreased gradually afterwards. The SIRS scores on the 1st day (1.05±1.08) and 3rd day (0.96± 1.11) after EF were significantly higher than that before EF (0.72±0.84),then decreased to 0.83±0.91, 0.49±0.73 and 0.32±0.60 on the 5th, 10th and 15th days after EF. The number of patients with diarrhea at 1, 3, 5, 10 and 15 days post-EF were 31, 26, 12, 13, and 7, respectively.Conclusions The longer the TPN lasts, the more severe the enteral refeeding syndrome becomes. Continuous EF is effective for the syndrome. Early enteral nutrition is useful in preventing it.

    Ventricular pacing is most commonly performed at the right ventricular (RV) apex. This is not without risk as placement requires crossing the tricuspid valve (TV) and may cause valvular dysfunction and dyssynchronous activation of the ventricles. The fact that the tricuspid valve lies more apically than the mitral valve allows for the possibility of pacing the ventricles from the right atrium (RA) via the “atrio-ventricular septum” without crossing the TV or entering the coronary sinus (CS). In order to mitigate far field activation inherent to current pacing technology, we constructed a novel lead in which the cathode and anode are both intra-myocardial. We demonstrate safety and efficacy of this novel lead for ventricular pacing at the atrio-ventricular septum in canines, including improved synchronous activation of both ventricles, improved differentiation in ventricular versus atrial sensing, while providing reliable ventricular capture, opening novel and a potentially safer alternative to human cardiac resynchronization therapy.

This report version adds documentation of an additional three month low boom test task. The key technical objective of this effort was to validate integrated airframe and propulsion technologies and design methodologies. These capabilities aspired to produce a viable supersonic vehicle design with environmental and performance characteristics. Supersonic testing of both airframe and propulsion technologies (including LM3: 97-023 low boom testing and April-June nozzle acoustic testing) verified LM s supersonic low-boom design methodologies and both GE and RRLW's nozzle technologies for future implementation. The N+2 program is aligned with NASA s Supersonic Project and is focused on providing system-level solutions capable of overcoming the environmental and performance/efficiency barriers to practical supersonic flight. NASA proposed "Initial Environmental Targets and Performance Goals for Future Supersonic Civil Aircraft". The LM N+2 studies are built upon LM s prior N+3 100 passenger design studies. The LM N+2 program addresses low boom design and methodology validations with wind tunnel testing, performance and efficiency goals with system level analysis, and low noise validations with two nozzle (GE and RRLW) acoustic tests.

  2. Morphine decreases enteric neuron excitability via inhibition of sodium channels.

    Directory of Open Access Journals (Sweden)

    Tricia H Smith

    Full Text Available Gastrointestinal peristalsis is significantly dependent on the enteric nervous system. Constipation due to reduced peristalsis is a major side-effect of morphine, which limits the chronic usefulness of this excellent pain reliever in man. The ionic basis for the inhibition of enteric neuron excitability by morphine is not well characterized as previous studies have mainly utilized microelectrode recordings from whole mount myenteric plexus preparations in guinea pigs. Here we have developed a Swiss-Webster mouse myenteric neuron culture and examined their electrophysiological properties by patch-clamp techniques and determined the mechanism for morphine-induced decrease in neuronal excitability. Isolated neurons in culture were confirmed by immunostaining with pan-neuronal marker, β-III tubulin and two populations were identified by calbindin and calretinin staining. Distinct neuronal populations were further identified based on the presence and absence of an afterhyperpolarization (AHP. Cells with AHP expressed greater density of sodium currents. Morphine (3 µM significantly reduced the amplitude of the action potential, increased the threshold for spike generation but did not alter the resting membrane potential. The decrease in excitability resulted from inhibition of sodium currents. In the presence of morphine, the steady-state voltage dependence of Na channels was shifted to the left with almost 50% of channels unavailable for activation from hyperpolarized potentials. During prolonged exposure to morphine (two hours, action potentials recovered, indicative of the development of tolerance in single enteric neurons. These results demonstrate the feasibility of isolating mouse myenteric neurons and establish sodium channel inhibition as a mechanism for morphine-induced decrease in neuronal excitability.

  3. Enteral nutrition for feeding severely underfed patients with anorexia nervosa.

    2012-09-01

    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/m(2). The mean BMI increased from 11.2 ± 0.7 kg/m(2) to 17.3 ± 1.6 kg/m(2) 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 refeeding syndrome. In conclusion, our findings show that, even in cases of extreme undernutrition, enteral feeding may be a well-tolerated way of feeding.

    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.

    2008-03-01

    Full Text Available Clostridium perfringens (C. perfringens is a normal inhabitant of the intestinal tract of chickens as well as a potential pathogen causing necrotic enteritis. C. perfringens only causes necrotic enteritis when it transforms from non-toxin producing type to toxin producing type. The alpha toxin, (phospholipase C is believed to be a key to the occurrence of Clostridial necrotic enteritis (CNE. The best known predisposing factor is mucosal damage, caused by coccidiosis that damages the intestinal lining, making the gut susceptible to infections including C. perfringens. The purpose of this study was to observe the chicken performance in experimental CNE and field cases of CNE. Diagnosis of CNE were made by latex agglutination test, isolation and identification of the agent. Pathological and histopathological changes were also observed. Experimentally, NE could be reproduced when Eimeria sp and C. perfringens spores are inoculated in chicken. Signs of an NE are wet litter and diarrhea, and an increase in mortality is not often obvious. The depression of growth rate and feed efficiency of chicken become noticeable by week 5 because of damage to the intestine and the subsequent reduction in digestion and absorption of food. Subclinical form of CNE was also frequently found in the field, leading to significant decreases in performance. Chicken gut samples examinations revealed that subclinical form of CNE causes damage to the intestinal mucosa caused by C. perfringens leads to decreased digestion and absorption, increased feed conversion ratio and reduced weight gain. Dual infection with C. perfringens and Eimeria sp. was frequently found in field. The results of these studies provide evidence for C. perfringens as a causative bacteria for growth depression.

    We investigated the occurrence and attenuation of several human enteric viruses (i.e., norovirus, adenovirus, Aichi virus 1, polyomaviruses, and enterovirus) as well as a plant virus, pepper mild mottle virus (PMMoV), at two surface flow wetlands in Arizona. The retention time in one of the wetlands was seven days, whereas in the other wetland it could not be defined. Water samples were collected at the inlet and outlet from the wetlands over nine months, and concentration of viral genomes was determined by quantitative polymerase chain reaction (qPCR). Of the human enteric viruses tested, adenovirus and Aichi virus 1 were found in the greatest prevalence in treated wastewater (i.e., inlet of the wetlands). Reduction efficiencies of enteric viruses by the wetlands ranged from 1 to 3 log10. Polyomaviruses were generally removed to below detection limit, indicating at least 2 to 4 log10 removal. PMMoV was detected in a greater concentration in the inlet of both wetlands for all the viruses tested (10(4) to 10(7) genome copies/L), but exhibited little or no removal (1 log10 or less). To determine the factors associated with virus genome attenuation (as determined by qPCR), the persistence of PMMoV and poliovirus type 1 (an enterovirus) was studied in autoclaved and natural wetland water, and deionized water incubated under three different temperatures for 21 days. A combination of elevated water temperature and biological activities reduced poliovirus by 1 to 4 log10, while PMMoV was not significantly reduced during this time period. Overall, PMMoV showed much greater persistence than human viruses in the wetland treatment.

    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.

    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.

    A blended diet for enteral nutrition is defined as home-made everyday food blended to a smooth 'single cream' consistency. At present, blended food is not recommended as a first choice. However, the wishes of parents who prefer to use blended food for their child need to be respected, and hospice policy for Children's Hospice South West is to replicate home conditions as far as possible. Therefore guidelines have been created for use of a blended diet. However, benefits in physical and emotional health need to be balanced against risks of tube blockage, contamination and digestive upsets.

    Slow transit constipation has been traditionally considered and classified as a functional disorder.However, clinical and manometric evidence has been accumulating that suggests how most of the motility alterations in STC might be considered of neuropathic type. In addition, further investigations showed that subtle alterations of the enteric nervous system, not evident to conventional histological examination, may be present in these patients. In the present article we will discuss these evidences, and will try to put them in relation with the abnormal motor function of the large bowel documented in this pathological condition.

  19. Microbial enhanced oil recovery: Entering the log phase

    Bryant, R.S.

    1995-12-31

    Microbial enhanced oil recovery (MEOR) technology has advanced internationally since 1980 from a laboratory-based evaluation of microbial processes to field applications. In order to adequately support the decline in oil production in certain areas, research on cost-effective technologies such as microbial enhanced oil recovery processes must focus on both near-term and long-term applications. Many marginal wells are desperately in need of an inexpensive improved oil recovery technology today that can assist producers in order to prevent their abandonment. Microbial enhanced waterflooding technology has also been shown to be an economically feasible technology in the United States. Complementary environmental research and development will also be required to address any potential environmental impacts of microbial processes. In 1995 at this conference, the goal is to further document and promote microbial processes for improved oil recovery and related technology for solving environmental problems.

    World's Biggest Astronomy WWW-Event Attracts Thousands of Students The Astronomy On-line Programme (See ESO Press Release 09/96 of 18 June 1996) began officially on 1 October and is now about to enter its most intense phase, known as the Hot Week . On 18 - 22 November, an estimated 4000 astronomy-interested, mostly young people in Europe and on four other continents will get together during five days in what - not unexpected - has become the world's biggest astronomy event ever organised on the World Wide Web. This carefully structured Programme is carried out in collaboration between the European Association for Astronomy Education (EAAE), the European Southern Observatory and the European Commission, under the auspices of the Fourth European Week for Scientific and Technological Culture. The Programme has already had a most visible impact on the school education of natural sciences in various countries; for instance, the Internet-connection of schools has been advanced in some, in order to allow groups to participate. There have been numerous contacts among the groups across the borders and there are clear signs that many Astronomy On-line participants have progressed to use the impressive possibilities of the Web in an efficient and structured way. There has been a lively media interest in Astronomy On-line all over Europe and it is expected to increase during the next week. The current status of Astronomy On-line It is obvious that the pilot function of the Astronomy On-line Programme in the use of the Web has been very effective and that the associated dissemination of astronomical knowledge has been successful. At this time, more than 650 groups have registered with Astronomy On-line. Most come from 31 different European countries and a few dozen groups are located in North and South America as well as in Asia and Australia. Together they have experienced the steady build-up of Astronomy On-line over the past weeks, by means of numerous contributions from a

    Children with intestinal failure suffer from insufficient intestinal length or function, making them dependent on parenteral nutrition (PN) for growth and survival. PN and its components are associated with many complications ranging from simple electrolyte abnormalities to life-threatening PN-associated liver disease, which is also called intestinal failure-associated liver disease (ILALD). From a nutrition perspective, the ultimate goal is to provide adequate caloric requirements and make the transition from PN to full enteral Nutrition (EN) successful. Upon review of the literature, we have summarized the most effective and innovative PN and EN therapies for this patient population. Antibiotic-coated catheters and antibiotic or ethanol locks can be implemented, as they appear effective in reducing catheter-related infection and thus further reduce the risk of IFALD. Lipid emulsions should be given judiciously. The use of an omega-3 fatty acid-based formulation should be considered in patients who develop IFALD. Trophic feeding is important for intestinal adaptation, and EN should be initiated early to help wean patients from PN. Long term management of children with IF continues to be an emerging field. We have entered uncharted territory as more children survive complications of IF, including IFALD. Careful monitoring and individualized management to ensure maintenance of growth with avoidance of complications are the keys to successful patient outcomes. PMID:20123271

    Feline coronaviruses (FCoV) comprise two biotypes: feline enteric coronaviruses (FECV) and feline infectious peritonitis viruses (FIPV). FECV is associated with asymptomatic persistent enteric infections, while FIPV causes feline infectious peritonitis (FIP), a usually fatal systemic disease in domestic cats and some wild Felidae. FIPV arises from FECV by mutation. FCoV also occur in two serotypes, I and II, of which the serotype I viruses are by far the most prevalent in the field. Yet, most of our knowledge about FCoV infections relates to serotype II viruses, particularly about the FIPV, mainly because type I viruses grow poorly in cell culture. Hence, the aim of the present work was the detailed study of the epidemiologically most relevant viruses, the avirulent serotype I viruses. Kittens were inoculated oronasally with different doses of two independent FECV field strains, UCD and RM. Persistent infection could be reproducibly established. The patterns of clinical symptoms, faecal virus shedding and seroconversion were monitored for up to 10 weeks revealing subtle but reproducible differences between the two viruses. Faecal virus, i.e. genomic RNA, was detected during persistent FECV infection only in the large intestine, downstream of the appendix, and could occasionally be observed also in the blood. The implications of our results, particularly our insights into the persistently infected state, are discussed.

    Porcine enteric sapovirus (PES) has been shown to cause diarrhea under experimental conditions in gnotobiotic piglets. However, the role of PES as enteric pathogens in porcine farms remains unclear. To further understand the PES-host interactions under field conditions, a serological survey was carried out. To this end the capsid gene of a PES isolate was cloned in the baculovirus expression system and an ELISA was developed based on virus-like particles from the baculovirus-expressed PES capsid protein. A total of 85 serum samples collected from pigs ranging from 8 weeks to over 54 weeks of age were analyzed. An overall seroprevalence to PESs of 62% was found, with significant differences (p<0.05) found between ages. Pigs younger than 10 weeks old and older than 12 weeks old showed high seroprevalences (70-100%), while pigs aged 10-12 weeks showed no detectable serum antibodies levels. Our results suggest that PES infections are common in pigs and that passively acquired maternal antibodies are soon replaced by actively acquired antibodies, whose titers increase gradually with age and that probably are maintained during lifetime.

    2015-01-01

    Full Text Available Introduction. The number of Salmonella isolated from clinical samples that are resistant to multiple antibiotics has increased worldwide. The aim of this study was to determine the prevalence of resistant Salmonella enterica isolated in Bangui. Methods. All enteric Salmonella strains isolated from patients in 2008 were identified and serotyped, and the phenotypes of resistance were determined by using the disk diffusion method. Nine resistance-associated genes, blaTEM, blaOXA, blaSHV, tetA, aadA1, catA1, dhfrA1, sul I, and sul II, were sought by genic amplification in seven S.e. Typhimurium strains. Results. The 94 strains isolated consisted of 47 S.e. Typhimurium (50%, 21 S.e. Stanleyville (22%, 18 S.e. Enteritidis (19%, 4 S.e. Dublin (4%, 4 S.e. Hadar (4%, and 1 S.e. Papuana (1%. Twenty-five (28% were multiresistant, including 20 of the Typhimurium serovar (80%. Two main phenotypes of resistance were found: four antibiotics (56% and to five antibiotics (40%. One S.e. Typhimurium isolate produced an extended-spectrum β-lactamase (ESBL. Only seven strains of S.e. Typhimurium could be amplified genically. Only phenotypic resistance to tetracycline and aminosides was found. Conclusion. S. Typhimurium is the predominant serovar of enteric S. enterica and is the most widely resistant. The search for resistance genes showed heterogeneity of the circulating strains.

  8. Spatio-Temporal Mapping and the Enteric Nervous System.

    Science.gov (United States)

    Hennig, Grant W

    Study of the enteric nervous system (ENS) is somewhat less glamorous than other body systems but offers a unique opportunity to study the sensory, interneuronal and motor outputs of a highly developed neural network in the same tissue. This has not been a trivial task, and even after a century, we still struggle to understand both the simple (e.g. reflexes) and complex (e.g. MMCs) behaviors the gut produces. On top of that, other control networks (such as ICC) that are integrated with ENS at varying levels, can modify ENS activity directly or indirectly. While many of the methods used to study the ENS were originally developed in other systems (e.g. brain/heart), a few were spawned "in the offal" so to speak, due to the unique characteristics of the gut. The brief perspective below outlines how spatio-temporal maps (ST Maps) originated and continue to flourish in GI research as a tool to describe and analyze the complexity of GI movements.I apologize that I am not able to specifically mention all the people involved in the development and use of ST Maps in enteric/motility research due to space constraints (GWH, July 2014).

    2015-09-01

    Three outbreaks of necrotic enteritis-like disease associated with Clostridium sordelii were diagnosed in commercial broiler chicken flocks with 18,000 to 31,000 birds between 18 and 26 days old. Clinical signs in the affected flocks included high mortality up to 2% a day, depression, and diarrhea. The main gross changes included segmental dilation of the small intestine with watery contents, gas, mucoid exudate, and roughened and uneven mucosa, occasionally covered with a pseudomembrane. Microscopic lesions in the small intestine were characterized by extensive areas of coagulative necrosis of the villi, fibrinous exudate in the lumen, and high numbers of large, Gram-positive rods, occasionally containing subterminal spores, seen in the necrotic tissue and lumen. These rods were identified as C. sordellii by immunohistochemistry. Clostridium sordellii was isolated in an almost pure culture from the intestine of affected birds. A retrospective study of commercial broiler chicken and turkey submissions to the California Animal Health and Food Safety Laboratory System revealed that C. sordellii had been isolated from intestinal lesions in outbreaks of necrotic enteritis-like disease in 8 of 39 cases, 5 times together with Clostridium perfringens and 3 times alone. The latter three cases are reported here.

    2014-06-21

    A 25-year-old man was admitted with the chief complaints of right flank pain, watery diarrhea, and fever. Blood tests revealed high levels of inflammatory markers, and infectious enteritis was diagnosed. A stool culture obtained on admission revealed no growth of any significant pathogens. Conservative therapy was undertaken with fasting and fluid replacement. On day 2 of admission, the fever resolved, the frequency of defecation reduced, the right flank pain began to subside, and the white blood cell count started to decrease. On hospital day 4, the frequency of diarrhea decreased to approximately 5 times per day, and the right flank pain resolved. However, the patient developed epigastric pain and increased blood levels of the pancreatic enzymes. Abdominal computed tomography revealed mild pancreatic enlargement. Acute pancreatitis was diagnosed, and conservative therapy with fasting and fluid replacement was continued. A day later, the blood levels of the pancreatic enzymes peaked out. On hospital day 7, the patient passed stools with fresh blood, and Campylobacter jejuni/coli was detected by culture. Lower gastrointestinal endoscopy performed on hospital day 8 revealed diffuse aphthae extending from the terminal ileum to the entire colon. Based on the findings, pancreatitis associated with Campylobacter enteritis was diagnosed. In the present case, a possible mechanism of onset of pancreatitis was invasion of the pancreatic duct by Campylobacter and the host immune responses to Campylobacter.

    Enteropathies in rabbits are difficult to diagnose; their etiology involves pathogens that act synergistically, causing damage to the intestine. The aim of the present study was isolate enteric pathogens from rabbits in Mexico. Using parasitological, bacteriological and molecular analyses, we screened 58 samples of the intestinal content of rabbits having a clinical history of enteric disease from the southeastern part of the State of Mexico. Out of the 58 samples analyzed, a total of 86 identifications were made, Eimeria spp. were found in 77.5%, followed by Aeromonas spp. in 15.5% and Escherichia coli in 8.6%, which were identified as enteropathogenic E. coli (EPEC), and the presence of the following agents was also confirmed: Salmonella spp., Klebsiella spp., Streptococcus spp., Staphylococcus aureus, Enterococcus spp., Mannheimia spp. and Rotavirus. The concurrent presence of Eimeria spp. with Aeromonas was frequent (15.5%); there was statistical significance for the presence of an association between the clinical profiles and Eimeria spp. (p=0.000), Mannheimia spp. (p=0.001), Salmonella spp., Klebsiella spp., Streptococcus spp. and Enterococcus spp. (p=0.006).

    Full Text Available The organisation of services to support the increasing number of people receiving enteral tube feeding (ETF at home varies across regions. There is evidence that multi-disciplinary primary care teams focussed on home enteral nutrition (HEN can provide cost-effective care. This paper describes the development and evaluation of a HEN Team in one UK city. A HEN Team comprising dietetians, nurses and a speech and language therapist was developed with the aim of delivering a quality service for people with gastrostomy tubes living at home. Team objectives were set and an underpinning framework of organisation developed including a care pathway and a schedule of training. Impact on patient outcomes was assessed in a pre-post test evaluation design. Patients and carers reported improved support in managing their ETF. Cost savings were realised through: (1 prevention of hospital admission and related transport for ETF related issues; (2 effective management and reduction of waste of feed and thickener; (3 balloon gastrostomy tube replacement by the HEN Team in the patient’s home, and optimisation of nutritional status. This service evaluation demonstrated that the establishment of a dedicated multi-professional HEN Team focussed on achievement of key objectives improved patient experience and, although calculation of cost savings were estimates, provided evidence of cost-effectiveness.

  13. Enteric viruses in a mangrove lagoon, survival and shellfish incidence

    Mangrove oysters (Crassostrea rhizophorae) were screened for enteric viruses. For 18 months oysters were collected from Cano Boqueron, a tropical mangrove lagoon on the southwest coast of Puerto Rico. This popular tourist resort has two primary sewage treatment plants which service 158 single family cabanas. In spite of the heavy seasonal input of sewage to Cano Boqueron and high densities of fecal coliform bacteria, enteric viruses were not detected in shellfish meat. Because no viruses were detected in the oysters, a virus survival study was performed. Poliovirus type 1 was placed in diffusion chambers in situ at two sites in Cano Boqueron. More than 95% of the poliovirus inactivation occurred within 24 h. Virus inactivation was significantly different by site, indicating different inactivation rates within the lagoon. Chamber studies done simultaneously with Escherichia coli did not reveal differences between sites. It is suggested that the sewage effluent had an antiviral effect in the absence of an antibacterial effect. This study demonstrates the importance for establishing microbial contamination standards for shellfish growing waters in the tropics based upon in situ studies with tropical species, e.g. mangrove oyster.

    The organisation of services to support the increasing number of people receiving enteral tube feeding (ETF) at home varies across regions. There is evidence that multi-disciplinary primary care teams focussed on home enteral nutrition (HEN) can provide cost-effective care. This paper describes the development and evaluation of a HEN Team in one UK city. A HEN Team comprising dietetians, nurses and a speech and language therapist was developed with the aim of delivering a quality service for people with gastrostomy tubes living at home. Team objectives were set and an underpinning framework of organisation developed including a care pathway and a schedule of training. Impact on patient outcomes was assessed in a pre-post test evaluation design. Patients and carers reported improved support in managing their ETF. Cost savings were realised through: (1) prevention of hospital admission and related transport for ETF related issues; (2) effective management and reduction of waste of feed and thickener; (3) balloon gastrostomy tube replacement by the HEN Team in the patient's home, and optimisation of nutritional status. This service evaluation demonstrated that the establishment of a dedicated multi-professional HEN Team focussed on achievement of key objectives improved patient experience and, although calculation of cost savings were estimates, provided evidence of cost-effectiveness.

    The spectacular success of parenteral nutrition in supporting patients during small intestinal adaptation after massive resection, tends to obscure the prolonged periods often needed for such adaptation to take place. After neonatal small intestinal resection for example, it may take more than five years before adaptation is complete. There is therefore a strong argument for examining ways in which adaptation can be facilitated, in particular, by the addition of novel substrates to enteral feeds. Pectin is completely fermented by colonic bacteria to short chain fatty acids. In the rat, addition of pectin to enteral feeds led to a more rapid adaptive response in both the small and large intestine after massive small intestinal resection, although faecal nitrogen losses were increased. In a similar rat model, the provision of 40% of non-protein energy as short chain triglycerides facilitated the adaptive response in the jejunum, colon, and pancreas. The importance of glutamine as a metabolic substrate for the small intestine makes it another potential candidate and some, but not all animal studies, have suggested a therapeutic effect: increasing the glutamine content of feeds to 25% of total amino acids produced enhanced jejunal and ileal hyperplasia, even on a hypocaloric feed, and an improved overall weight gain. Studies in humans are very limited, but such promising results in the experimental animal suggest that this is probably a fruitful area for further study.

    Gastrointestinal side effects, particularly diarrhea, are still the main reasons for discontinuation of enteral nutrition. Gelatinization of liquid meal for the prevention of diarrhea has been reported as effective. The purpose of this study was to investigate the effects of gelatinization of liquid meal on gastric emptying. Ten healthy volunteers were studied two times, with 2-week interval between tests. The total calorific value was set at 225 kcal, and 3 test meals were prepared: liquid meal and 2 types of gelatinized meals. These 2 types of gelatinized meals are different viscosity. (13)C-sodium acetate (100 mg) was thoroughly mixed, and exhaled air was sampled. The results of gastric emptying were expressed as the time of peak excretion (Tmax), and absorption was expressed as the area under the (13)CO2 curve up to Tmax (AUC-Tmax). At the same time, blood samples were collected to measure levels of blood glucose, insulin and gastrin. The mean value of Tmax were 52.0, 77.3 and 85.6 min. Compared to liquid meal, gastric emptying for gelatinized meals was significantly delayed. The mean value of AUC-Tmax were 22.7, 28.7 and 33.7%dose, respectively, and no significant differences in absorption were seen. No significant differences existed in blood glucose, gastrin and insulin. Gelatinization of liquid meal delays gastric emptying. Gelatinized liquid meal may be useful for the management of diarrhea accompanied with enteral nutrition without influencing gastrointestinal hormone and blood glucose.

    Chronic obstructive pulmonary disease (COPD) is a progressive, chronic disease, in which malnutrition can have an undesirable effect. Therefore, the patient's nutritional status is critical for optimizing outcomes in COPD. The initial nutrition assessment is focused on identifying calorically compromised COPD patients in order to provide them with appropriate nutrition. Nutritional intervention consists of oral supplementation and enteral nutrition to prevent weight loss and muscle mass depletion. Evaluation of nutritional status should include past medical history (medications, lung function, and exercise tolerance) and dietary history (patient's dietary habits, food choices, meal patterns, food allergy information, and malabsorption issues), in addition to physiological stress, visceral proteins, weight, fat-free mass, and body mass index. The current medical literature conflicts regarding the appropriate type of formulation to select for nutritional intervention, especially regarding the amount of calories from fat to provide COPD patients. This review article focuses on the enteral product formulations currently available, and how they are most appropriately utilized in patients with COPD.

    Stool samples from children < 5 years of age with diarrhea (N = 239) were examined for enteric pathogens using a combination of culture, enzyme-immunoassay, and polymerase chain reaction methods. Pathogens were detected in 122 (51%) stool samples; single pathogens were detected in 37.2% and co-pathogens in 13.8% of samples. Norovirus, rotavirus, and diarrheagenic Escherichia coli (DEC) were the most frequently detected pathogens (15.5%, 13.4%, and 11.2%, respectively); Salmonella, adenovirus, and Aeromonas were detected less frequently (7.9%, 7.1%, and 4.2%). The most commonly detected DEC was enteroaggregative E. coli (5.4%). Resistance to ≥ 3 antimicrobials was observed in 60% (18/30) of the bacterial pathogens. Salmonella resistance to ciprofloxacin (63.1%) has become a concern. Enteric viral pathogens were the most significant causative agents of childhood diarrhea in Tripoli. Bacterial pathogens were also important contributors to pediatric diarrhea. The emergence of ciprofloxacin-resistant Salmonella represents a serious health problem that must be addressed by Libyan health authorities PMID:21633024

    The purpose of this study was to analyze the organizational models of home enteral feeding used in 5 local health authorities (LHAs) in the Veneto region (Italy). By comparing these models with the main guidelines, the authors have attempted to determine the "minimum standards" to be adopted at an organizational level. This 3-stage study analyzes procedures, precoded actions, and recordable processes. Stage 1: objectives were defined, work methods selected, and reference guidelines chosen. Stage 2: flowcharts were drafted to show the actions and work paths taken for the 5 LHAs. Stage 3: flowcharts were compared with data from the literature. The study shows that very different organizational models exist. For instance, by comparing organizational processes with the procedures prescribed by the guidelines, it can be seen that the mean percentages of actions taken by the 5 LHAs, for patients in both rest homes and nursing homes, rarely exceeds the threshold of 50% (on a scale from 0% to 100%). This study shows that home enteral feeding is neither optimized nor uniform in the 5 LHAs and that standardized methods are not used for clinical monitoring.

    Enteric coccidiosis may cause significant morbidity and mortality in juvenile brown kiwi (Apteryx mantelli). Morphology of sporulated oocysts indicates that at least two Eimeria species are able to infect the brown kiwi. A histological study of the endogenous stages of coccidia was undertaken in the intestinal tracts of ten naturally infected young kiwi. Sequential sectioning of the entire intestinal tract allowed identification and recording of the distribution of the various coccidial life stages. Macromeronts measuring 268 × 162 μm when mature were found mainly within the lamina propria of the proximal one third of the small intestine. A smaller form of lamina propria meront was also identified (8.7 × 6.4 μm) with a similar distribution to the macromeronts. Small meronts (4.4 × 3.8 μm) were also identified in mucosal epithelial cells, with the overall peak in distribution within the intestinal tract being distal to the lamina propria meronts. Three morphologically distinctive gametocytes were identified. Type A gametocytes contained within epithelial cells shared the same distribution as the epithelial meronts. Polyps containing large numbers of type B gametocytes within the distal intestinal tract were found in two cases, and type C gametocytes were identified throughout the entire intestinal tract in one case only. The observational nature of this study precludes complete knowledge of the parasite life cycles using histology alone. However, it is likely that each of the three morphologically distinct gametocytes represents a separate species of enteric coccidia.

    Full Text Available In today’s globalized world, businesses look to expand to have a global presence. Restaurant businesses have expanded internationally using franchising. This study sought to determine the critical success factors (CSFs of a franchised restaurant system entering the Kenyan market from the franchisors’ perspective. It sought to establish how franchisors define, identify, and evaluate success. This study provides a theoretical framework that helps to understand the background of why organizations seek to expand using franchising method and consequently the CSFs of franchised restaurants entering the Kenyan market. The study used qualitative methodology with the use of in-depth interviews for collecting data. The results yielded CSFs from the franchisors’ perspective. As revealed by the study, the CSFs include brand power/concept, competitive environment, government policies, distance management, cultural appeal, excellent selection of franchisees, good site/location selection, good relationship with the franchisees, and proper contract management. These findings can be used by restaurant franchises that seek to establish successful businesses in the Kenyan market and other similar regional markets. The Africa franchise partners may also find some useful information from this article as they seek to set up the Franchise Association of Kenya. Other franchise businesses may also benefit from some aspects of the study.

However, in clinical practice, MMF dose reduction, interruption, or discontinuation due to hematological and gastrointestinal (GI side-effects occurred in up to 50% of the patients. Large retrospective analyses have demonstrated that patients requiring MMF dose manipulation due to adverse events experienced a higher rate of rejection and graft loss. Enteric-coated mycophenolate sodium (EC-MPS was developed with the goal of improving upper GI side-effects. Here, we review the efficacy and safety of EC-MPS in de novo kidney transplant recipient, and in stable renal transplant patients who were converted from MMF. The changes in GI-related adverse events using patient-reported outcome instruments are also reviewed.Keywords: enteric-coated mycophenolate sodium, mycophenolate mofetil, kidney transplant, efficacy, gastrointestinal tolerability

    Full Text Available Enteric methane (CH4 emissions in ruminants have attracted considerable attention due to their impact on greenhouse gases and the contribution of agricultural practices to global warming. Over the last two decades, a number of approaches have been adopted to mitigate CH4 emissions. However, the mechanisms of methanogenesis have still not been fully defined. According to the genome sequences of M. ruminantium in the rumen and of M. AbM4 in the abomasum, the pathways of carbon dioxide (CO2 reduction and formate oxidation to CH4 have now been authenticated in ruminants. Furthermore, in the light of species or genera description of methanogens, the precursors of methanogenesis discovered in the rumen and research advances in related subjects, pathways of acetate dissimilation via Methanosarcina and Methanosaeta as well as metabolism of methanol to CH4 might be present in the rumen, although neither process has yet been experimentally demonstrated in the rumen. Herein the research advances in methanogenesic mechanisms including existing and potential mechanisms are reviewed in detail. In addition, further research efforts to understand the methanogenesis mechanism should focus on isolation and identification of more specific methanogens, and their genome sequences. Such increased knowledge will provide benefits in terms of improved dietary energy utilization and a reduced contribution of enteric CH4 emissions to total global greenhouse gas emissions from the ruminant production system.

    Objective To develop a rapid and definite diagnostic test of bacterial enteritis caused by pathogenic enterobacteria, the most frequent etiologic agent of infectious enteritis in the world.Methods A set of conventional PCR assays were applied to detect and identify salmonella, shigella,and E. coli O157:H7 directly from pure culture and fecal samples. The general primers of pathogenic enterobacteria were located on the uidA gene, which were found not only in E. coli nuclear acid, but also in Shigella and salmonella genes. Shigella primer was from ipaH gene whose coded invasive plasmid relative antigen existed both in plasmid and in genome. The primers of salmonella were designed from the 16SrRNA sequence. The primer of E. coli O157:H7 was taken from eaeA gene.Five random primers were selected for RAPD. The detection system included common PCR,semi-nested PCR and RAPD. Results This method was more sensitive, specific and efficient and its processing was rapid and simple. For example, the method could be used to specifically detect and identify salmonella, shigella, and E. coli O157:H7, and its sensitivity ranged from 3 to 50 CFU, and its detection time was 4 hours. Conclusion This PCR method, therefore, can serve as a rourine and practical protocol for detecting and identifying pathogenic microorganisms from clinical samples.

    Full Text Available The purpose of this study was to examine student entry into a campus recreation center based on seven demographics (gender, ethnicity, age, class standing, intercollegiate athlete vs. non-athlete, students with self-reported disability vs. non-disability, and campus residence in order to determine who would be most likely to enter the recreation center. Subjects were from a mid-western, four year state-assisted institution with combined enrollment of 23,932 undergraduate and graduate students. Of the 23,932 enrolled, 14,032 students were examined in this study. Information on student entry to the recreation center was collected through the university’s student information system. Data was analyzed and interpreted using chi-square analysis. Results of the study show statistically significant differences in the demographics except the student disability demographic. More males than females, more African Americans than other ethnicities, more traditionally aged (18-25 students than non-traditional students, more underclassmen than seniors, more athletes and non-athletes, more residents than commuters were likely to enter the campus recreation center. The findings in this study could be used by collegiate recreational sport directors and administrators, in the United States and internationally, for future ideas about programming in similar recreation settings.

    Full Text Available Enteroaggregative Escherichia coli (EAEC are quite heterogeneous category of an emerging enteric pathogen associated with cases of acute or persistent diarrhea worldwide in children and adults, and over the past decade has received increasing attention as a cause of watery diarrhea, which is often persistent. EAEC infection is an important cause of diarrhea in outbreak and non-outbreak settings in developing and developed countries. Recently, EAEC has been implicated in the development of irritable bowel syndrome, but this remains to be confirmed. EAEC is defined as a diarrheal pathogen based on its characteristic aggregative adherence (AA to HEp-2 cells in culture and its biofilm formation on the intestinal mucosa with a “stacked-brick” adherence phenotype, which is related to the presence of a 60 MDa plasmid (pAA. At the molecular level, strains demonstrating the aggregative phenotype are quite heterogeneous; several virulence factors are detected by polymerase chain reaction; however, none exhibited 100% specificity. Although several studies have identified specific virulence factor(s unique to EAEC, the mechanism by which EAEC exerts its pathogenesis is, thus, far unknown. The present review updates the current knowledge on the epidemiology, chronic complications, detection, virulence factors, and treatment of EAEC, an emerging enteric food borne pathogen.

    The CANDU pressurized heavy water reactor's principal design features suit it particularly well for technology transfer and localization. When the first commercial CANDU reactors of 540 MWe entered service in 1971, Canada's population of less than 24 million supported a 'medium' level of industrial development, lacking the heavy industrial capabilities of larger countries like the USA, Japan and Europe. A key motivation for Canada in developing the CANDU design was to ensure that Canada would have the autonomous capacity to build and operate nuclear power reactors without depending on foreign sources for key components or enriched fuel.

    The hyperthermophilic archaeon Pyrodictium grows in the form of a macroscopically visible network. It consists of cells entrapped in an extracellular matrix of hollow tubules, the "cannulae." Here, we present the three-dimensional structure of a single cell in conjunction with two extracellular cannulae, as determined by cryo-electron microscopy. To achieve this, the information from two independent tilt series of the same specimen was combined, with the specimen rotated in the second series. In the three-dimensional tomographic reconstruction, we were able to trace the two cannulae in their full length, in particular, also inside the cell. One cannula enters the periplasmic space, while the other cannula contacts the surface of the cell, the S-layer. This indicates that the cannulae interconnect individual cells with each other on the level of their periplasmic space; we do not, however, have evidence that they enter the cytoplasm of the cells. The implications of these data for possible functions of the cannulae are discussed.

    2015-01-01

    For long it was believed that a particular population of enteric neurons, referred to as intrinsic primary afferent neuron (IPAN)s, encodes mechanical stimulation. We recently proposed a new concept suggesting that there are in addition mechanosensitive enteric neurons (MEN) that are multifunctional. Based on firing pattern MEN behaved as rapidly, slowly, or ultra-slowly adapting RAMEN, SAMEN, or USAMEN, respectively. We aimed to validate this concept in the myenteric plexus of the gastric corpus, a region where IPANs were not identified and existence of enteric sensory neurons was even questioned. The gastric corpus is characterized by a particularly dense extrinsic sensory innervation. Neuronal activity was recorded with voltage sensitive dye imaging after deformation of ganglia by compression (intraganglionic volume injection or von Fry hair) or tension (ganglionic stretch). We demonstrated that 27% of the gastric neurons were MEN and responded to intraganglionic volume injection. Of these 73% were RAMEN, 25% SAMEN, and 2% USAMEN with a firing frequency of 1.7 (1.1/2.2), 5.1 (2.2/7.7), and of 5.4 (5.0/15.5) Hz, respectively. The responses were reproducible and stronger with increased stimulus strength. Even after adaptation another deformation evoked spike discharge again suggesting a resetting mode of the mechanoreceptors. All MEN received fast synaptic input. Fifty five percent of all MEN were cholinergic and 45% nitrergic. Responses in some MEN significantly decreased after perfusion of TTX, low Ca(++)/high Mg(++) Krebs solution, capsaicin induced nerve defunctionalization and capsazepine indicating the involvement of TRPV1 expressing extrinsic mechanosensitive nerves. Half of gastric MEN responded to intraganglionic volume injection as well as to ganglionic stretch and 23% responded to stretch only. Tension-sensitive MEN were to a large proportion USAMEN (44%).

    2014-11-01

    Robust detection of enteric protozoa is a critical step toward determining the etiology of diarrhea. Widespread use of conventional microscopy, culturing and antigen detection in both industrial and developing countries is limited by relatively low sensitivity and specificity. Refinements of these conventional approaches that reduce turnaround time and instrumentation have yielded strong alternatives for clinical and research use. However, advances in molecular diagnostics for protozoal, bacterial, viral and helminth infections offer significant advantages in studies seeking to understand pathogenesis, transmission and long-term consequences of infectious diarrhea. Quantitation of enteropathogen burden and highly multiplexed platforms for molecular detection dramatically improve predictive power in emerging models of diarrheal etiology, while eliminating the expense of multiple tests.

Multiple sequence alignment suggested that the UL54 gene was highly conserved in Alphaherpesvirinae and was similar to the other herpesviral UL54 gene. Phylogenetic analysis of the DEV UL54 gene revealed that DEV had a close evolutionary relationship with Gallid, Herpesvirus 2 (GaHV-2, Gallid Herpesvirus 3 (GaHV-3, Meleagrid Herpesvirus1 (MeHV-1 and should belong to a single cluster within the Alphaherpesvirinae subfamily.

    Full Text Available Gastrointestinal involvement is frequent in patients with systemic lupus erythematosus (SLE. Eosinophilic gastroenteritis, however, has only rarely been described in rheumatological conditions, despite its reported connection to autoimmune diseases, such as hypereosinophilic syndrome, vasculitides, and systemic mastoidosis. It presents typically with abdominal pain and diarrhea and is only exceptionally associated with ascites. Diagnosis can be problematic, as several other clinical conditions (malignancies, infection/tuberculosis, and inflammatory bowel diseases have to be ruled out. It is basically a nonsurgical disease, with excellent recovery on conservative treatment. We report the rare case of a young woman with overlap syndrome who presented with abdominal pain and ascites. The diagnosis of eosinophilic enteritis was made based on clinical, radiological, and laboratory criteria. The patient was treated with corticosteroids with excellent response.

    A 49-year-old female was admitted with chief complaint of fecaluria on March 4th 1993. A radiation therapy had been performed for uterocervical cancer 18 years ago. The small intestine and bladder was detected by DIP and cystogram simultaneously. It was diagnosed as an ileovesical fistula. A segmental resection of the ileum with partial cystectomy was performed on March 23rd. Histopathologically, the ileum showed a radiation enteritis. Eventually, we diagnosed that this ileovesical fistula was caused by radiation. After operation, an incompletion of suture occurred. So we made an ileostomy secondarily and performed hyperbaric oxygen therapy. The patient was getting well temporarily but died of gastric hemorrhage on May 1st. (author)

    Full Text Available Although the disciplines of bacteriology and virology frequently come together in the setting of a diagnostic medical microbiology laboratory, the two scientific fields are usually miles apart. The microbiologists basically form two non-overlapping groups of scientists, the bacteriologists and virologists, that go to separate meetings and that do not easily intermingle. Some recent research findings about elegant virus-bacterium interactions may change this situation. Obviously, interactions between these two microbes can occur only when they co-localize, which most likely occurs in the gut/intestines where 1014 commensal bacteria reside (the microbiota. We review findings on the following enteric microbial tandems: norovirus- Enterobacter cloacae, mouse mammary tumor virus (MMTV – bacterial lipopolysaccharide (LPS, poliovirus and reovirus – intestinal bacteria. The close bacterium-virus interplay may also present options to develop unique therapeutic strategies for those infected and to prevent further virus spread and thus minimize the risk for the community.

    Full Text Available Free perforation is one of the most feared complications of the intestinal tuberculosis. The terminal ileum is the most common site of perforation, while the majority of (90% perforations are solitary. Herein, we describe a case of a 25-year-old male who presented with generalized peritonitis requiring an emergency exploratory laparotomy, which revealed pan-enteric perforation characterized by multiple perforations of the small bowel extending 10–15 cm from the DJ flexure up to the terminal ileum. The perforations were primarily closed, while 6–8 cm of the diseased terminal ileum was resected and the two ends were brought out as double-barreled ostomy. To the best of our knowledge, such an extensive tuberculous perforation of the small bowel has not been previously reported in the literature before.

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

    2002-01-01

    Enteritis necroticans is a segmental necrotizing infection of the jejunum and ileum caused by Clostridium perfringens, Type C. The disease occurs sporadically in parts of Asia, Africa, and the South Pacific, where it primarily affects children with severe protein malnutrition. The disease is extremely rare in developed countries, where it has been seen primarily in diabetics. Two cases have previously been reported in the United States, one in a child with poorly controlled Type 1 diabetes. A 66-year-old woman with a 12-year history of Type 2 diabetes mellitus developed severe abdominal pain and bloody diarrhea after eating a meal of turkey sausage. She died unattended at home. An autopsy showed peritonitis and segmental necrosis of the jejunum and ileum. Microscopic examination showed Gram-positive club-shaped bacilli consistent with Clostridia coating a necrotic mucosa. Products of cpa and cpb genes of C. perfringens, Type C were identified in the necrotic jejunum by polymerase chain reaction amplification.

    Full Text Available The analysis of the incidence of acute intestinal infections in children was carried out in Irkutsk region. The study demonstrated significant increase of the incidence of acute intestinal infections in Irkutsk region and revealed exceedance of all-Russia indicators. It is established that bacterial intestinal infections dominate. Among the bacterial pathogens of acute intestinal infections dominated opportunistic bacteria of the family Enterobacteriaceae. The Analysis also revealed the change of quantitative composition in the long-term aspect, and a significant increase in the proportion of bacteria of the genus Klebsiella. Etiological structure of acute enteric infections in children in recent years has changed. The proportion of viruses has increased. The viral infection has had higher growth rate in comparison with bacterial infections.

    Full Text Available Cryptogenic Multifocal Ulcerous Stenosing Enteritis (CMUSE is a rare idiopathic disease of the small bowel. Its origin and pathophysiology has not been well described. Clinicopathologic features include unexplained ileal strictures with supercial ulceration. We present a case of a 31-year-old HIV positive lady who was admitted with complaints of recurrent abdominal pain and constipation. Laboratory investigations revealed iron deciency anemia. Ultrasonography of the abdomen showed dilated bowel loops and a subsequent barium follow through showed ve strictures in the ileum. Segmental small bowel resection with end-to-end anastomosis was performed. Grossly ileum showed ve ileal strictures. The diagnosis of CMUSE was made on histopathology after ruling out other causes of strictures. The present case highlights the importance of considering CMUSE in patients with chronic or recurrent episodes of intestinal obstruction with multiple small intestinal ulcers and strictures after other common causes have been ruled out.

    Enteral nutrition (EN) is a valuable clinical intervention for patients of all ages in a variety of care settings. Along with its many outcome benefits come the potential for adverse effects. These safety issues are the result of clinical complications and of process-related errors. The latter can occur at any step from patient assessment, prescribing, and order review, to product selection, labeling, and administration. To maximize the benefits of EN while minimizing adverse events requires that a systematic approach of care be in place. This includes open communication, standardization, and incorporation of best practices into the EN process. This document provides recommendations based on the available evidence and expert consensus for safe practices, across each step of the process, for all those involved in caring for patients receiving EN.

    This study assessed the provision of education and support to parents of children on home enteral nutrition (HEN), current dietetic support available and perceived challenges facing parents and carers. From the 39 responses (13%), 29 (83%, n = 35) parents suggested services for HEN need improvement. 29 (74%, n = 39) parents wanted more structured follow up and 22 (56%) would like one person to co-ordinate HEN, education and discharge. 7 parents (18%) reported a need for further education of health care professionals (HCP). Hospital dietitians were the most common HCPs reported to provide support to patients following discharge. Specialist paediatric HEN dietetic services working in a dedicated HEN team, who would provide accurate training and education and liaise with both parents and community care services post discharge should be in place. This would facilitate transfer to community care, reduce hospital re-admissions, outpatient department attendances and costs.

    This study examined the relationships between social and demographic characteristics (ie, gender, race, year in school, desired residency choice, and socioeconomic background), motivations for entering the profession of podiatric medicine (extrinsic and intrinsic rewards), and negative attitudes toward treating elderly patients. The study used ordinary least squares multiple regression models to analyze data from a random, national sample of 448 podiatric medical students. In particular, the ordinary least squares models were developed to determine the independent effect of intrinsic and extrinsic rewards on negative attitudes toward treating elderly patients. Consistent with the study hypotheses, after adjusting for social and demographic characteristics, the study found extrinsic rewards to have strong positive relationships with negative attitudes toward treating elderly patients, and intrinsic rewards to have strong negative relationships with negative attitudes toward treating elderly patients. The authors discussed the implications of the findings for podiatric physicians and educators training podiatric medical students.

    Gastrointestinal duplication cyst is a rare congenital anomaly that may occur anywhere along the gastrointestinal tract from the tongue to the anus. Such cysts occur most commonly in the small bowel and about half are in the mesenteric border of the ileum. Such cystic duplications communicate only rarely with the intestinal lumen although the cysts are attached to the intestine and may even share a common wall with the adjacent alimentary tract. These lesions can vary in shape, being cystic or tubular, and often show the same structure of the adjacent normal bowel. It is usually asymptomatic and complications are rare but they may include obstruction by volvulus or intussusception, bleeding, infection, and perforation. When diagnosed these lesions should be surgically resected to avoid future possible complications. The authors present a case of enteric cystic duplication and its ultrasound appearance in a 12-month-old Caucasian female infant cause of acute abdominal pain and intestinal obstruction, thus requiring urgent surgery.

    Soybean meal-induced enteritis (SBMIE) is a well-described condition in the distal intestine of salmonids, and saponins have been implicated as the causal agent. However, the question remains whether saponins alone cause SBMIE. Moreover, the dose-response relationship has not been described. In a 10 week feeding trial with Atlantic salmon, a highly purified (95%) soya saponin preparation was supplemented (0, 2, 4, 6, or 10 g/kg) to two basal diets, one containing fishmeal as the major protein source (FM) and the other 25% lupin meal (LP). Saponins caused dose-dependent increases in the severity of inflammation independent of the basal diet, with concomitant alterations in digestive functions and immunological marker expression. Thus, saponins induced inflammation whether the diet contained other legume components or not. However, responses were often the same or stronger in fish fed the corresponding saponin-supplemented LP diets despite lower saponin exposure, suggesting potentiation by other legume component(s).

  17. Enteric neural crest cells regulate vertebrate stomach patterning and differentiation.

    2015-01-15

    In vertebrates, the digestive tract develops from a uniform structure where reciprocal epithelial-mesenchymal interactions pattern this complex organ into regions with specific morphologies and functions. Concomitant with these early patterning events, the primitive GI tract is colonized by the vagal enteric neural crest cells (vENCCs), a population of cells that will give rise to the enteric nervous system (ENS), the intrinsic innervation of the GI tract. The influence of vENCCs on early patterning and differentiation of the GI tract has never been evaluated. In this study, we report that a crucial number of vENCCs is required for proper chick stomach development, patterning and differentiation. We show that reducing the number of vENCCs by performing vENCC ablations induces sustained activation of the BMP and Notch pathways in the stomach mesenchyme and impairs smooth muscle development. A reduction in vENCCs also leads to the transdifferentiation of the stomach into a stomach-intestinal mixed phenotype. In addition, sustained Notch signaling activity in the stomach mesenchyme phenocopies the defects observed in vENCC-ablated stomachs, indicating that inhibition of the Notch signaling pathway is essential for stomach patterning and differentiation. Finally, we report that a crucial number of vENCCs is also required for maintenance of stomach identity and differentiation through inhibition of the Notch signaling pathway. Altogether, our data reveal that, through the regulation of mesenchyme identity, vENCCs act as a new mediator in the mesenchymal-epithelial interactions that control stomach development. © 2015.

    The objective of this study was to analyze the nutritional quality and viscosity of blenderized enteral tube feedings (BTFs) from four hospitals in the Philippines. Samples of two different BTFs (one standard and one modified) were collected from each hospital on three separate occasions and analyzed for macronutrients, micronutrients, and viscosity. There was considerable variation among the BTFs for the concentrations of most nutrients measured. For standard BTF samples, the caloric density ranged from 66-123 kcal/100g and the percentages of total weight for protein, carbohydrate, and fat ranged from 1.5-4.0%, 8.6-21.4%, and 0.27-3.40%, respectively. Levels of specific vitamins were undetectable in 10 standard and 15 modified BTF samples. In samples where vitamin levels were detectable, results were: vitamin A, 625-8850 IU/kg; riboflavin, 0.40-5.00 mg/kg; and pyridoxine, 0.14-3.00 mg/kg. Mineral concentrations also varied greatly (eg calcium, 64-524 mg/kg; sodium, 148-886 mg/kg; iron, 3.0-13.7 mg/kg; and zinc, 1.8- 11.5 mg/kg). Correlation coefficients were statistically significant only for carbohydrate (r = 0.48, P = 0.017). Measured values tended to be lower than expected values for all nutrients, although the difference was statistically significant only for calories (P = 0.023). The viscosity of BTF samples ranged from 2.3-45,060 centipoise, excluding three samples that were too viscous for analysis. This study demonstrates that hospital prepared blenderized enteral tube feedings render unpredictable levels of micronutrients and macronutrients and appear likely to deliver less than the desired amounts of nutrients. Additionally, the viscosity of these feedings may be unsuitable for infusion through feeding tubes.

    Full Text Available BACKGROUND: Tissue culture-adapted Tulane virus (TV, a GI.1 rhesus enteric calicivirus (ReCV, and a mixture of GII.2 and GII.4 human norovirus (NoV-containing stool sample were used to intrastomacheally inoculate juvenile rhesus macaques (Macaca mulatta in order to evaluate infection caused by these viruses. METHODOLOGY & FINDINGS: Two of the three TV-inoculated macaques developed diarrhea, fever, virus-shedding in stools, inflammation of duodenum and 16-fold increase of TV-neutralizing (VN serum antibodies but no vomiting or viremia. No VN-antibody responses could be detected against a GI.2 ReCV strain FT285, suggesting that TV and FT285 represent different ReCV serotypes. Both NoV-inoculated macaques remained asymptomatic but with demonstrable virus shedding in one animal. Examination of duodenum biopsies of the TV-inoculated macaques showed lymphocytic infiltration of the lamina propria and villous blunting. TV antigen-positive (TV+ cells were detected in the lamina propria. In most of the TV+ cells TV co-localized perinuclearly with calnexin--an endoplasmic reticulum protein. A few CD20+TV+ double-positive B cells were also identified in duodenum. To corroborate the authenticity of CD20+TV+ B cells, in vitro cultures of peripheral blood mononuclear cells (PBMCs from healthy macaques were inoculated with TV. Multicolor flow cytometry confirmed the presence of TV antigen-containing B cells of predominantly CD20+HLA-DR+ phenotype. A 2-log increase of viral RNA by 6 days post inoculation (p<0.05 suggested active TV replication in cultured lymphocytes. CONCLUSIONS/SIGNIFICANCE: Taken together, our results show that ReCVs represent an alternative cell culture and animal model to study enteric calicivirus replication, pathogenesis and immunity.

    Background Gastrointestinal side effects, particularly diarrhea, are still the main reasons for discontinuation of enteral nutrition. Gelatinization of liquid meal for the prevention of diarrhea has been reported as effective. The purpose of this study was to investigate the effects of gelatinization of liquid meal on gastric emptying. Methods Ten healthy volunteers were studied two times, with 2-week interval between tests. The total calorific value was set at 225 kcal, and 3 test meals were prepared: liquid meal and 2 types of gelatinized meals. These 2 types of gelatinized meals are different viscosity. 13C-sodium acetate (100 mg) was thoroughly mixed, and exhaled air was sampled. The results of gastric emptying were expressed as the time of peak excretion (Tmax), and absorption was expressed as the area under the 13CO2 curve up to Tmax (AUC-Tmax). At the same time, blood samples were collected to measure levels of blood glucose, insulin and gastrin. Results The mean value of Tmax were 52.0, 77.3 and 85.6 min. Compared to liquid meal, gastric emptying for gelatinized meals was significantly delayed. The mean value of AUC-Tmax were 22.7, 28.7 and 33.7%dose, respectively, and no significant differences in absorption were seen. No significant differences existed in blood glucose, gastrin and insulin. Conclusions Gelatinization of liquid meal delays gastric emptying. Gelatinized liquid meal may be useful for the management of diarrhea accompanied with enteral nutrition without influencing gastrointestinal hormone and blood glucose. PMID:27942287

  4. Identification of novel pathogenicity loci in Clostridium perfringens strains that cause avian necrotic enteritis.

    Directory of Open Access Journals (Sweden)

    Dion Lepp

    Full Text Available Type A Clostridium perfringens causes poultry necrotic enteritis (NE, an enteric disease of considerable economic importance, yet can also exist as a member of the normal intestinal microbiota. A recently discovered pore-forming toxin, NetB, is associated with pathogenesis in most, but not all, NE isolates. This finding suggested that NE-causing strains may possess other virulence gene(s not present in commensal type A isolates. We used high-throughput sequencing (HTS technologies to generate draft genome sequences of seven unrelated C. perfringens poultry NE isolates and one isolate from a healthy bird, and identified additional novel NE-associated genes by comparison with nine publicly available reference genomes. Thirty-one open reading frames (ORFs were unique to all NE strains and formed the basis for three highly conserved NE-associated loci that we designated NELoc-1 (42 kb, NELoc-2 (11.2 kb and NELoc-3 (5.6 kb. The largest locus, NELoc-1, consisted of netB and 36 additional genes, including those predicted to encode two leukocidins, an internalin-like protein and a ricin-domain protein. Pulsed-field gel electrophoresis (PFGE and Southern blotting revealed that the NE strains each carried 2 to 5 large plasmids, and that NELoc-1 and -3 were localized on distinct plasmids of sizes approximately 85 and approximately 70 kb, respectively. Sequencing of the regions flanking these loci revealed similarity to previously characterized conjugative plasmids of C. perfringens. These results provide significant insight into the pathogenetic basis of poultry NE and are the first to demonstrate that netB resides in a large, plasmid-encoded locus. Our findings strongly suggest that poultry NE is caused by several novel virulence factors, whose genes are clustered on discrete pathogenicity loci, some of which are plasmid-borne.

    Nutrition is integral to the care of individuals with cystic fibrosis (CF). Better nutritional status is associated with improved pulmonary function. In some individuals with CF, enteral tube feeding can be useful in achieving optimal nutritional status. Current nutrition guidelines do not include detailed recommendations for enteral tube feeding. The Cystic Fibrosis Foundation convened an expert panel to develop enteral tube feeding recommendations based on a systematic review of the evidence and expert opinion. These guidelines address when to consider enteral tube feeding, assessment of confounding causes of poor nutrition in CF, preparation of the patient for placement of the enteral feeding tube, management of the tube after placement and education about enteral feeding. These recommendations are intended to guide the CF care team, individuals with CF, and their families through the enteral tube feeding process.

    Pathogenic simian immunodeficiency virus (SIV) infection is associated with enteropathy, which likely contributes to AIDS progression. To identify candidate etiologies for AIDS enteropathy, we used next-generation sequencing to define the enteric virome during SIV infection in nonhuman primates. Pathogenic, but not nonpathogenic, SIV infection was associated with significant expansion of the enteric virome. We identified at least 32 previously undescribed enteric viruses during pathogenic SIV infection and confirmed their presence by using viral culture and PCR testing. We detected unsuspected mucosal adenovirus infection associated with enteritis as well as parvovirus viremia in animals with advanced AIDS, indicating the pathogenic potential of SIV-associated expansion of the enteric virome. No association between pathogenic SIV infection and the family-level taxonomy of enteric bacteria was detected. Thus, enteric viral infections may contribute to AIDS enteropathy and disease progression. These findings underline the importance of metagenomic analysis of the virome for understanding AIDS pathogenesis.

    Soil available nitrogen content is an important index reflecting soil fertility. It provides dynamic information for land reclamation and ecological restoration if soil available nitrogen can be monitored and evaluated using hyperspectral technology. Facing the study blank of soil available nitrogen in National Mine Park and the deficiency of poor computational efficiency of partial least squares regression (PLSR) method, the present paper presents the relationship between soil spectrum and soil available nitrogen based on spectrum curves (ranging from 350 to 2 500 nm) of 30 salinized chestnut soil samples, which were collected from southern mountain coal waste scenic spot, located in Jinhuagong mine in Datong city, Shanxi Province, China (one part of Jinhuagong national mine park). Soil reflection spectrum was mathematically manipulated into first derivative and inverse-log spectral curves, then a corresponding estimation model was built and examined by PLSR and Enter-partial least squares regression (Enter-PLSR) based on characteristic absorption. The result indicated that Enter-PLSR corresponding estimation model greatly increased the computation efficiency by reducing the number of independent variables to 12 from 122 in case of a close accuracy of PLS corresponding estimation model. By using hyperspectral technology and Enter-PLSR method, the study blank of soil available nitrogen in National Mine Park was filled. At the same time, the computation efficiency problem of PLSR was resolved.

    Typhoid and paratyphoid are febrile illnesses, due to a bacterial infection, which remain common in many low- and middle-income countries. The World Health Organization (WHO) currently recommends the fluoroquinolone antibiotics in areas with known resistance to the older first-line antibiotics. To evaluate fluoroquinolone antibiotics for treating children and adults with enteric fever. We searched The Cochrane Infectious Disease Group Specialized Register (February 2011); Cochrane Central Register of Controlled Trials (CENTRAL), published in The Cochrane Library (2011, Issue 2); MEDLINE (1966 to February 2011); EMBASE (1974 to February 2011); and LILACS (1982 to February 2011). We also searched the metaRegister of Controlled Trials (mRCT) in February 2011. Randomized controlled trials examining fluoroquinolone antibiotics, in people with blood, stool or bone marrow culture-confirmed enteric fever. Two authors independently assessed the trial's methodological quality and extracted data. We calculated risk ratios (RR) for dichotomous data and mean difference for continuous data with 95% confidence intervals (CI).Comparative effectiveness has been interpreted in the context of; length of treatment, dose, year of study, known levels of antibiotic resistance, or proxy measures of resistance such as the failure rate in the comparator arm. Twenty-six studies, involving 3033 patients, are included in this review.Fluoroquinolones versus older antibiotics (chloramphenicol, co-trimoxazole, amoxicillin and ampicillin)In one study from Pakistan in 2003-04, high clinical failure rates were seen with both chloramphenicol and co-trimoxazole, although resistance was not confirmed microbiologically. A seven-day course of either ciprofloxacin or ofloxacin were found to be superior. Older studies of these comparisons failed to show a difference (six trials, 361 participants).In small studies conducted almost two decades ago, the fluoroquinolones were demonstrated to have fewer

    During 1999, as in previous years, the NADYA-SENPE Group has maintained an annual register of patients with Artificial Nutrition at Home in order to keep up to date our available knowledge of this therapy. The present paper analyzes the results of the sixth National Register of patients under treatment with Enteral Nutrition at Home corresponding to 1999, produced with the co-operation of twenty-three centres in the Spanish national health network. The data were collected through a closed questionnaire included on our web site (www.nadya-senpe.com). Apart from epidemiological information, the form includes the indication that led to the prescription of nutrition, nutritional treatment, access path, complications and admissions to hospital, follow-up of the treatment, patients' quality of life and progress. All of the data are processed by the co-ordinating team. The Nutrition Unit at La Paz Teaching Hospital in Madrid has acted as the group co-ordinator. During 1999, a total of 2,262 patients at the twenty-three collaborating centres followed treatment with Home Enteral Nutrition (NED in its Spanish acronym). The mean age was 63.6 (19.67 years (males: 57.6%; females: 42.3%). The mean time with nutritional treatment is 5.89 (4.25 months. The neurological alterations (37.5%) and neoplasias (36.8%) were the most frequent indications for NED. Most patients used oral administration (50.7%), the use of artificial routes is less frequent, with 5NG being used on 27.9% and PEG on 12.7%. The polymeric formulas are the ones most commonly used (87.7%). The number of complications recorded amounted to 1,403 episodes, representing 0.62 complications per patient per year, of which 40.8% were gastro-intestinal (0.26 complications per patient per year) and 18.7% were mechanical complications, with only 9 recorded cases of bronchoaspiration. It was necessary to admit patients to hospital on 836 occasions (0.38 admissions per patient), albeit generally for causes not associated with

    The fat content of human milk provides the majority of calories for infants. However, large fat losses in human milk have been observed using enteral pump systems, causing poor growth in infants. The fat may adhere in the pump system. Lecithin, a phospholipid, has been used in the food industry as a lipophilic emulsifier of fats. The purpose of this study was to evaluate the effects of lecithin on the delivery of human milk fat from an enteral pump. It is hypothesized that the addition of lecithin would decrease the fat loss during human milk delivery. Six mothers at a mature stage of lactation (>4 weeks of lactation) donated human milk. The human milk samples were stored separately at -20 degrees C before analysis and evaluated individually. The fat content of the milk samples was estimated by the creamatocrit method, in which the samples were centrifuged in a standard hematocrit tube and the fat layer read with vernier calipers and expressed as a percentage of the length of the milk column to the nearest 0.5%. The accuracy of this method is 92%. The Kangaroo 324 Feeding Pump (Sherwood Medical, St. Louis, MO) was used as the continuous pump system. The human milk samples were divided into either control samples without lecithin or with lecithin (1 or 0.5 g soy lecithin dissolved in 50 mL milk). All samples were pumped at 10 to 50 mL/h for at least 4 hours. The pumped milk was collected in an iced container, and creamatocrits were determined in duplicate. There was significant fat loss in the control milk samples compared with the milk samples with added lecithin. The average fat loss was 58% +/- 13% for control samples and 55% +/- 26% for the milk with 0.5 g soy lecithin. Milk with 1 g soy lecithin averaged 2% +/- 2% fat loss. The pumping rate had no effect on fat loss. The greatest fat loss (70% +/- 6%)occurred during the first 4 hours of pumping. The addition of 1 g soy lecithin per 50 mL milk decreased the human milk fat loss during intermittent pumping and may

    Postoperative ileus (POI) is a common consequence of abdominal surgery that increases the risk of postoperative complications and morbidity. We investigated the cellular mechanisms and immune responses involved in the pathogenesis of POI. We studied a mouse model of POI in which intestinal manipulation leads to inflammation of the muscularis externa and disrupts motility. We used C57BL/6 (control) mice as well as mice deficient in Toll-like receptors (TLRs) and cytokine signaling components (TLR-2(-/-), TLR-4(-/-), TLR-2/4(-/-), MyD88(-/-), MyD88/TLR adaptor molecule 1(-/-), interleukin-1 receptor [IL-1R1](-/-), and interleukin (IL)-18(-/-) mice). Bone marrow transplantation experiments were performed to determine which cytokine receptors and cell types are involved in the pathogenesis of POI. Development of POI did not require TLRs 2, 4, or 9 or MyD88/TLR adaptor molecule 2 but did require MyD88, indicating a role for IL-1R1. IL-1R1(-/-) mice did not develop POI; however, mice deficient in IL-18, which also signals via MyD88, developed POI. Mice given injections of an IL-1 receptor antagonist (anakinra) or antibodies to deplete IL-1α and IL-1β before intestinal manipulation were protected from POI. Induction of POI activated the inflammasome in muscularis externa tissues of C57BL6 mice, and IL-1α and IL-1β were released in ex vivo organ bath cultures. In bone marrow transplantation experiments, the development of POI required activation of IL-1 receptor in nonhematopoietic cells. IL-1R1 was expressed by enteric glial cells in the myenteric plexus layer, and cultured primary enteric glia cells expressed IL-6 and the chemokine monocyte chemotactic protein 1 in response to IL-1β stimulation. Immunohistochemical analysis of human small bowel tissue samples confirmed expression of IL-1R1 in the ganglia of the myenteric plexus. IL-1 signaling, via IL-1R1 and MyD88, is required for development of POI after intestinal manipulation in mice. Agents that interfere with

    Full Text Available Abstract Background There is paucity of published data on human immunodeficiency virus (HIV seroprevalence among migrant workers entering Middle-East particularly Kuwait. We took advantage of the routine screening of migrants for HIV infection, upon arrival in Kuwait from the areas with high HIV prevalence, to 1 estimate the HIV seroprevalence among migrant workers entering Kuwait and to 2 ascertain if any significant time trend or changes had occurred in HIV seroprevalence among these migrants over the study period. Methods The monthly aggregates of daily number of migrant workers tested and number of HIV seropositive were used to generate the monthly series of proportions of HIV seropositive (per 100,000 migrants over a period of 120 months from January 1, 1997 to December 31, 2006. We carried out spectral analysis of these time series data on monthly proportions (per 100,000 of HIV seropositive migrants. Results Overall HIV seroprevalence (per 100,000 among the migrants was 21 (494/2328582 (95% CI: 19 -23, ranging from 11 (95% CI: 8 – 16 in 2003 to 31 (95% CI: 24 -41 in 1998. There was no discernable pattern in the year-specific proportions of HIV seropositive migrants up to 2003; in subsequent years there was a slight but consistent increase in the proportions of HIV seropositive migrants. However, the Mann-Kendall test showed non-significant (P = 0.741 trend in de-seasonalized data series of proportions of HIV seropositive migrants. The spectral density had a statistically significant (P = 0.03 peak located at a frequency (radians 2.4, which corresponds to a regular cycle of three-month duration in this study. Auto-correlation function did not show any significant seasonality (correlation coefficient at lag 12 = – 0.025, P = 0.575. Conclusion During the study period, overall a low HIV seroprevalence (0.021% was recorded. Towards the end of the study, a slight but non-significant upward trend in the proportions of HIV seropositive

    To cope with the economical and technical evolutions of the communication market and to better compete with or complement terrestrial networks, satellite operators are requiring more flexible satellites. It allows a better fleet planning potential and back-up policy, a more standardized and efficient procurement process, mission adaptation to market evolution and the possibility of early entry in new markets. New technologies that are developed either for terrestrial networks or for space defense applications would become soon available to satellite and equipment manufacturers. A skilful mix of these new technologies with the older and more mature ones should boost satellite performances and bring flexibility to the new generation of communication satellites. This paper reviews the economical and technical environment of the space communication business for the next decade. It identifies the needs and levels of flexibility that are required by the market but also allowed by technologies, in both a top-down and bottom-up approach.

    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. circle Neutral oral contrast ensures an equivalent delineation of the bowel. (orig.)

    Despite the benefits and the widespread use of enteral and tube feeding (ETF) some patients experience complications, which can be divided in three categories: mechanical, e. g., tube blockage or removal; gastrointestinal, e. g., vomiting, diarrhea; and metabolic, e. g., re-feeding syndrome, hyperglycemia. The type and frequency of complications related to tube feeding varies considerably in accordance with the access to the intestinal tract (e. g., nasoenteric vs. percutaneous gastric vs. small bowel), the composition of the formula diet used, and the severity of the underlying disease. For example, tube-related complications have been reported to occur in 0-20 % and gastrointestinal complications in 8-65 % of patients during early postoperative feeding via a needle catheter jejunostomy (NCJ) using comparable techniques. The complication rate can be reduced by careful observance of guidelines on tube feeding including those related to food composition, administration rate, portion size, food temperature, and supervision of the patient. Gastrointestinal side effects (including diarrhea) are without doubt the most frequent.

  16. Enteral Nutrition for Older Adults in Healthcare Communities.

    2014-08-01

    Older adults living in healthcare communities (HCCs) have multiple comorbidities and are at increased risk of malnutrition and unintended weight loss. Aging affects nearly every system as well as body composition and structure, causing physiological changes that can affect nutrition status. A significant percentage (56%) of residents who live in nursing facilities require extensive help to eat and have dental problems such as ill-fitting dentures, missing teeth, and swallowing problems, which can lead to inadequate caloric intake and unintended weight loss. Alzheimer disease or dementia is prevalent in both nursing facilities and in assisted living/residential care communities, where it affects 45% of older adults. In cognitively impaired residents, most tube feeding placements occur in the acute care setting and result in significant use of additional healthcare resources, along with high postinsertion mortality rates within 60 days of insertion. Nursing facilities receiving Medicare or Medicaid funding must abide by state and federal regulations and undergo rigorous surveys while balancing complex decisions related to initial placement of feeding tubes. Healthcare professionals must recognize the importance of establishing nutrition treatment goals that are resident centered and that respect the unique values and personal decisions of the older adult. Informed choice, resident-centered care decisions, and the review of living wills and/or advance directives are essential in the decision-making process. After enteral nutrition is started, healthcare practitioners must carefully review the physician's orders and administer and monitor the resident's tolerance, checking for potential complications.

  17. Causal events enter awareness faster than non-causal events

    Philosophers have long argued that causality cannot be directly observed but requires a conscious inference (Hume, 1967). Albert Michotte however developed numerous visual phenomena in which people seemed to perceive causality akin to primary visual properties like colour or motion (Michotte, 1946). Michotte claimed that the perception of causality did not require a conscious, deliberate inference but, working over 70 years ago, he did not have access to the experimental methods to test this claim. Here we employ Continuous Flash Suppression (CFS)—an interocular suppression technique to render stimuli invisible (Tsuchiya & Koch, 2005)—to test whether causal events enter awareness faster than non-causal events. We presented observers with ‘causal’ and ‘non-causal’ events, and found consistent evidence that participants become aware of causal events more rapidly than non-causal events. Our results suggest that, whilst causality must be inferred from sensory evidence, this inference might be computed at low levels of perceptual processing, and does not depend on a deliberative conscious evaluation of the stimulus. This work therefore supports Michotte’s contention that, like colour or motion, causality is an immediate property of our perception of the world. PMID:28149698

    Role flexibility is considered central to a health policy agenda stressing workforce redesign measures and professional role boundary change. Extensions in health professionals' role boundaries may involve the incorporation of new or 'vacant' roles, as well as the competitive acquisition of others. In the present study, the experiences of dietitians with extended roles in home enteral tube feeding (HETF) were explored and considered within the context of workforce role transition. Six semi-structured interviews conducted with dietitians specialising in HETF were undertaken and the emergent role development for dietitians in HETF was explored. Dietetic HETF roles emerged as a form of diversification, occupying a task 'vacancy', commonly on an opportunistic basis. Role overlap in these community based tasks was negotiated with community nurses, privately funded industry nurses and other medical staff. Notably, role conflict was encountered only with nutrition nurse specialists. To date, a lack of role exclusivity in a small and confined speciality field with multiple potential competitors has resulted in surprisingly little role conflict. Financial constraints within the National Health Service are considered likely to favour a privately funded service model of delivery, and this may have implications for dietitians specialising in this field. Dietitians also perceived an increase in professional status as a result of extended roles. © 2012 The Authors Journal of Human Nutrition and Dietetics © 2012 The British Dietetic Association Ltd.

    1969-04-01

    Twenty-six, ten-week-old mink were infected by force feeding by pipette 2 ml of a tissue suspension containing a Wisconsin strain of mink enteritis virus. Four days later, diarrhea and partial or complete loss of appetite developed simultaneously in all of the animals. Squinting and occasional vomiting were also observed. By the sixth day after inoculation, all of the mink were anorectic and weak. Anorexia persisted for 48 to 96 hours. Diarrhea and vomiting continued until the eighth to ninth day after exposure. For the first two days after the appearance of diarrhea, the feces contained large quantities of mucus and intestinal casts were seen frequently in the droppings. Thereafter, the feces consisted mostly of yellowish green, watery fluid and contained no casts. Some of the animals died on the eighth day after infection. Those which survived were severely dehydrated and debilitated, but resumed eating and achieved complete clinical recovery within the next five to six days.Leukopenia, i.e., total leukocyte count of less than 5,000 cells per mm(3) of blood, was found in seven of nine mink examined during the height of the disease. Leukopenic animals were deficient in both lymphocytes and neutrophils.

    2010-03-01

    Patients suffering from dementia or significant cognitive impairment (SCI) due to neurologic injury routinely receive percutaneous endoscopic gastrostomy (PEG) due to swallowing difficulty or lack of appetite. This review discusses current data and opinion regarding the risks and benefits of PEG in these populations. The current data regarding PEG placement in patients with dementia or SCI due to neurologic injury do not confirm either improvement or worsening of survival. Significant risk factors for poor prognosis after PEG include sex, hypoalbuminemia, age, chronic heart failure, and subtotal gastrectomy. Complications associated with enteral nutrition are minor and easily controlled when managed by a nutritional team. Alternative options for feeding elderly demented patients are available for family members considering PEG. In contrast to previously published data regarding worse clinical outcomes in the dementia and SCI populations receiving PEG, recent data suggest that clinical outcomes in this population are no different than in other patient populations receiving PEG. A prospective, randomized study is needed to ascertain whether PEG is appropriate and beneficial in the dementia/SCI populations.

    Full Text Available Today we are faced with an aging society that may develop malnutrition because of dysphagia related to dementia, stroke, and malignancy seen often in the elderly. The preferred form of nutritional supplementation for this group is enteral nutrition, and the most appropriate long-term method is by use of a gastrostomy. Percutaneous endoscopic gastrostomy (PEG was first introduced in 1980 as an alternative to the traditional operative procedure and rapidly became the preferred procedure. In geriatric patients, the principal indications are neurological dysphagia and malnutrition, related to an underlying disease or anorexia-cachexia in very elderly. PEG is contraindicated in the presence of respiratory distress, previous gastric resection, total esophageal obstruction, coagulation disorders and sepsis in the elderly. Common complications include wound infection, leakage, hemorrhage, and fistula in the general population, but aspiration pneumonia is the major case of death in this group. Risks and complications of PEG must be discussed with patients and their families; and the decision for percutaneous endoscopic gastrostomy insertion should only be made after careful consideration and discussion between managing physicians, allied health professionals, and the patient and/or family. Four ethical principles may help make feeding decisions: beneficence, non-maleficence, autonomy and justice. Attentive long-term care after tube replacement is mandatory. Acceptance of percutaneous endoscopic gastrostomy placement by patients and their families tends to increase once favorable outcomes are offered.

    Full Text Available Purpose: The present study was performed to assess the current susceptibility pattern of blood isolates of Salmonella spp from a super specialty hospital in North India against nalidixic acid, ciprofloxacin and azithromycin and compare the in vitro and in vivo response against azithromycin. Materials and Methods: We evaluated the minimum inhibitory concentration′s (MIC′s of 107 blood isolates of Salmonella spp against nalidixic acid, azithromycin and ciprofloxacin and correlated in vitro and in vivo response of azithromycin from the treatment and discharge summaries from the Hospital Information System (HIS software. Results: Among the 107 isolates evaluated, 94 (87.8% were nalidixic acid-resistant (NAR Salmonella and 36 were resistant to azithromycin by MIC testing. The MIC 90 value for azithromycin was 24 μg/mL. Among the 57 treatment histories evaluated using the HIS software, 19 (33% patients had documented clinical non-response to azithromycin which required change of therapy. Conclusions: The present study observed a higher MIC 90 values for azithromycin compared to Salmonella isolates from Western studies. There was also a documented clinical non-response against azithromycin. The in vitro and in vivo findings in this study suggest a guarded use of azithromycin for cases of enteric fever in India. The study also augments the reversal of resistance pattern in favour of chloramphenicol, ampicillin and trimethoprim - sulfamethoxazole.

    There has been increased attention on the importance of identifying and distinguishing the differences between stress-induced hyperglycemia (SH), newly diagnosed hyperglycemia (NDH), and hyperglycemia in persons with established diabetes mellitus (DM). Inpatient blood glucose control is now being recognized as not only a cost issue for hospitals but also a concern for patient safety and care. The reasons for the increased incidence of hyperglycemia in hospitalized patients include preexisting DM, undiagnosed DM or prediabetes, SH, and medication-induced hyperglycemia with resulting transient blood glucose variability. It is clear that identifying and documenting hyperglycemia in hospitalized patients with and without a previous diagnosis of DM and initiating prompt insulin treatment are important. Agreement on the optimum treatment goals for hyperglycemia remains quite controversial, and the benefits of intensive glucose management may be lost at the cost of hypoglycemia in intensive care unit patients. Nutrition support in the form of enteral nutrition (EN) increases the risk of hyperglycemia in both critical and non-critically ill hospitalized patients. Reasons for beginning a tube feeding are the same whether a person has NDH or DM. What differs is how to incorporate EN into the established insulin management protocols. The risk for hyperglycemia with the addition of EN is even higher in those without a previous diagnosis of DM. This review discusses the incidence of hyperglycemia, the pathogenesis of hyperglycemia, factors contributing to hyperglycemia in the hospitalized patient, glycemic management goals, current glycemic management recommendations, and considerations for EN formula selection, administration, and treatment.

    Little is known about the needs or characteristics of transgender individuals in substance abuse treatment settings. Transgender (n=199) and non-transgender (cisgender, n=13440) individuals were compared on psychosocial factors related to treatment, health risk behaviors, medical and mental health status and utilization, and substance use behaviors within a database that documented individuals entering substance abuse treatment in San Francisco, CA from 2007–2009 using logistic and linear regression analyses (run separately by identified gender). Transgender men (assigned birth sex of female) differed from cisgender men across many psychosocial factors, including having more recent employment, less legal system involvement, greater incidence of living with a substance abuser, and greater family conflict, while transgender women (assigned birth sex of male) were less likely to have minor children than cisgender women. Transgender women reported greater needle use and HIV testing rates were greater among transgender women. Transgender men and women reported higher rates of physical health problems, mental health diagnoses, and psychiatric medications but there were no differences in service utilization. There were no differences in substance use behaviors except that transgender women were more likely to endorse primary methamphetamine use. Transgender individuals evidence unique strengths and challenges that could inform targeted services in substance abuse treatment. PMID:24561017

    Neural crest cells (NCCs) are a population of multipotent cells that migrate extensively during vertebrate development. Alterations to neural crest ontogenesis cause several diseases, including cancers and congenital defects, such as Hirschprung disease, which results from incomplete colonization of the colon by enteric NCCs (ENCCs). We investigated the influence of the stiffness and structure of the environment on ENCC migration in vitro and during colonization of the gastrointestinal tract in chicken and mouse embryos. We showed using tensile stretching and atomic force microscopy (AFM) that the mesenchyme of the gut was initially soft but gradually stiffened during the period of ENCC colonization. Second-harmonic generation (SHG) microscopy revealed that this stiffening was associated with a gradual organization and enrichment of collagen fibers in the developing gut. Ex-vivo 2D cell migration assays showed that ENCCs migrated on substrates with very low levels of stiffness. In 3D collagen gels, the speed of the ENCC migratory front decreased with increasing gel stiffness, whereas no correlation was found between porosity and ENCC migration behavior. Metalloprotease inhibition experiments showed that ENCCs actively degraded collagen in order to progress. These results shed light on the role of the mechanical properties of tissues in ENCC migration during development.

    Carbidopa/levodopa enteral suspension (CLES; Duopa) is a suspension or gel formulation of carbidopa/levodopa that is approved by the USA Food and Drug Administration for the treatment of advanced Parkinson's disease patients with motor fluctuations. CLES is delivered at a constant rate continuously throughout the day into the jejunum through an infusion pump via a PEG-J tube implanted surgically. The efficacy of CLES was established in the USA based on a randomized, double-blind, double-dummy, active controlled, parallel group and 12-week study, in which mean daily OFF time was reduced by 4.0 h, compared to 1.9 h with oral immediate release carbidopa/levodopa. The CLES hardware consists of a cassette containing the drug, a pump to deliver the drug and tubing to connect the PEG-J to the pump. It is critical to understand the appropriate conversion of the carbidopa/levodopa daily dosages to the CLES dosage and how to program the pump and titrate CLES to achieve the most effective dose. We describe one methodology for patient selection, outpatient titration and pump programming.

  8. Selective Induced Altered Coccidians to Immunize and Prevent Enteritis

    2016-01-01

    Microbiomic flora in digestive tract is pivotal to the state of our health and disease. Antibiotics affect GI, control composition of microbiome, and shift equilibrium from health into disease status. Coccidiosis causes gastrointestinal inflammation. Antibiotic additives contaminate animal products and enter food chain, consumed by humans with possible allergic, antibiotic resistance and enigmatic side effects. Purposed study induced nonpathogenic, immunogenic organisms to protect against disease and abolish antibiotics' use in food animals and side effects in man. Diverse species of Coccidia were used as model. Immature organisms were treated with serial purification procedure prior to developmental stages to obtain altered strains. Chicks received oral gavage immunized with serial low doses of normal or altered organisms or sham treatment and were challenged with high infective normal organisms to compare pathogenicity and immunogenicity. Mature induced altered forms of E. tenella and E. necatrix lacked developmental stage of “sporocysts” and contained free sporozoites. In contrast, E. maxima progressed to normal forms or did not mature at all. Animals that received altered forms were considerably protected with higher weight gain and antibody titers against challenge infection compared to those that received normal organisms (p < 0.05). This is the first report to induce selected protective altered organisms for possible preventive measures to minimize antibiotic use in food animals. PMID:27721824

    Gastrointestinal (GI) disease is a debilitating feature of human immunodeficiency virus (HIV) infection that can occur in the absence of histopathological abnormalities or identifiable enteropathogens. However, the mechanisms of GI dysfunction are poorly understood. The present study was undertaken to characterize changes in resident and inflammatory cells in the enteric nervous system (ENS) of macaques during the acute stage of simian immunodeficiency virus (SIV) infection to gain insight into potential pathogenic mechanisms of GI disease. Ganglia from duodenum, ileum, and colon were examined in healthy and acutely infected macaques by using a combination of routine histology, double-label immunofluorescence and in situ hybridization. Evaluation of tissues from infected macaques showed progressive infiltration of myenteric ganglia by CD3+ T cells and IBA1+ macrophages beginning as early as 8 days postinfection. Quantitative image analysis revealed that the severity of myenteric ganglionitis increased with time after SIV infection and, in general, was more severe in ganglia from the small intestine than in ganglia from the colon. Despite an abundance of inflammatory cells in myenteric ganglia during acute infection, the ENS was not a target for virus infection. This study provides evidence that the ENS may be playing a role in the pathogenesis of GI disease and enteropathy in HIV-infected people. PMID:17392357

    With the recent development of CRISPR technology, it is becoming increasingly easy to engineer the genome. Genome-editing systems based on CRISPR, as well as transcription activator-like effector nucleases (TALENs) and zinc-finger nucleases (ZFNs), are becoming valuable tools for biomedical research, drug discovery and development, and even gene therapy. However, for each of these systems to effectively enter cells of interest and perform their function, efficient and safe delivery technologies are needed. This Review discusses the principles of biomacromolecule delivery and gene editing, examines recent advances and challenges in non-viral and viral delivery methods, and highlights the status of related clinical trials.

    2008-08-01

    The present research is based on the hypothesis that leaky enteric-coated pellets formulations are able to provide sustained input for drugs that have an absorption window, such as ranitidine hydrochloride, without jeopardizing their bioavailability. Leaky enteric-coated pellets formulations are defined as enteric-coated pellets that allow some of the drug to be released from the formulation in gastric fluid. Different approaches to making leaky enteric-coated pellets were investigated using extrusion-spheronization followed by spray coating. Leaky enteric coats were formulated using a commonly used enteric polymer, Eudragit L 30 D-55, combined with soluble compounds including lactose, PEG 8000 and surfactants (Span 60 (hydrophobic) or Tween 80 (hydrophilic)). The rate of drug release from the formulations in simulated gastric fluid can be tailored by varying the additive's amount or type. All leaky enteric-coated formulations studied completely released the drugs within 30 min after changing dissolution medium to phosphate buffer, pH 6. Predictions of plasma concentration-time profiles of the model drug ranitidine hydrochloride from leaky enteric-coated pellets in fasted conditions and from immediate-release formulations were performed using computer simulations. Simulation results are consistent with a hypothesis that leaky enteric-coated pellets formulations provide sustained input for drugs shown to have an absorption window without decreasing bioavailability. The sustained input results from the combined effects of the formulation and GI transit effects on pellets. The present research demonstrates a new application of knowledge about gastrointestinal transit effects on drug formulations. It also shows that enteric-coating polymers have new applications in areas other than the usual enteric-coated formulations. The hypothesis that a leaky enteric-coated pellets formulation may maintain or increase the bioavailability of drugs that have a window of absorption

    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.

    2016-05-01

    Hajj, the annual Muslim pilgrimage to Mecca, Saudi Arabia is a unique mass gathering event that attracts approximately 3 million pilgrims from around the globe. This diverse pilgrim population coupled with the nature of the performed activities raise major public health concerns in the host country with potential global implications. Although gastroenteritis and diarrhea are common among the pilgrims performing Hajj, the microbial etiologies of these infections are still unknown. We used molecular and antigenic approaches to identify the main pathogens associated with Hajj diarrhea. 544 fecal samples from pilgrims suffering from diarrhea whilst performing Hajj during three consecutive seasons (2011-2013) and 99 control samples from 2011 were screened for 16 pathogens that include bacterial, parasitic and viral etiologies that are commonly associated with diarrheal infections. At least one of the screened pathogens could be detected in 42% (n=228) of the samples from the diarrheal cases. Bacteria were the main agents detected in 83% (n=189) of the positive samples, followed by viral and parasitic agents detected in 6% (n=14) and 5% (n=12) respectively. We have also standardized a 16S-based metagenomic approach to identify the gut microbiome in diarrheal cases and non-diarrheal controls in 76 samples. Also, we have standardized a shotgun metagenomics protocol for the direct characterization (diagnosis) of enteric pathogens without cultivation. This approach was used successfully to identify viral (adenovirus) and bacterial causes of Enterotoxigenic E. coli diarrhea from Hajj samples. The findings in this study fill in clear gaps in our knowledge of the etiologies associated with diarrheal infections during Hajj. Foodborne bacteria were the major contributors to Hajj-diarrheal infections. This was coupled with the increased incidences of antimicrobial resistance loci associated with the identified bacteria. These findings would help the public health policy makers to

    Chitosan is known to have bactericidal and antifungal activity. Although human noroviruses are the leading cause of non-bacterial gastroenteritis, information on the efficacy of chitosan against foodborne viruses is very limited. The objective of this work was to determine the effectiveness of different molecular weight chitosans against the cultivable human norovirus and enteric virus surrogates, feline calicivirus, FCV-F9, murine norovirus, MNV-1, and bacteriophages, MS2 and phiX174. Five purified chitosans (53, 222, 307, 421, ~1150 kDa) were dissolved in water, 1% acetic acid, or aqueous HCl pH = 4.3, sterilized by membrane filtration, and mixed with equal volume of virus to obtain a final concentration of 0.7% chitosan and 5 log(10) PFU/ml virus. Virus-chitosan suspensions were incubated for 3 h at 37 °C. Untreated viruses in PBS, in PBS with acetic acid, and in PBS with HCl were tested as controls. Each experiment was run in duplicate and replicated at least twice. Water-soluble chitosan (53 kDa) reduced phiX174, MS2, FCV-F9 and MNV-1 titers by 0.59, 2.44, 3.36, and 0.34 log(10) PFU/ml respectively. Chitosans in acetic acid decreased phiX174 by 1.19-1.29, MS2 by 1.88-5.37, FCV-F9 by 2.27-2.94, and MNV-1 by 0.09-0.28 log(10) PFU/ml, respectively. Increasing the MW of chitosan corresponded with an increasing antiviral effect on MS2, but did not appear to play a role for the other three tested viral surrogates. Overall, chitosan treatments showed the greatest reduction for FCV-F9, and MS2 followed by phiX174, and with no significant effect on MNV-1.

    Full Text Available Sources of antibiotic resistant organisms, including concentrated animal feeding operations (CAFOs, may lead to environmental surface and groundwater contamination with resistant enteric bacteria of public health concern. The objective of this research is to determine whether Salmonella, Escherichia coli, Yersinia enterocolitica, and enterococci resistant to clinically relevant antibiotics are present in surface and groundwater sources in two eastern North Carolina counties, Craven and Wayne. 100 surface and groundwater sites were sampled for Salmonella, E. coli, and enterococci, and the bacteria isolated from these samples were tested for susceptibility to clinically relevant antibiotics. Salmonella were detected at low levels in some surface but not groundwater. E. coli were in surface waters but not ground in both counties. Enterococci were present in surface water and a small number of groundwater sites. Yersinia was not found. Bacterial densities were similar in both counties. For Salmonella in surface water, the most frequent type of resistance was to sulfamethoxazole. There was no ciprofloxacin resistance. There were a few surface water E. coli isolates resistant to chloramphenicol, gentamicin, and ampicillin. Enterococci in surface water had very low levels of resistance to vancomycin, chloramphenicol, ampicillin, and streptomycin. E. coli and enterococci are present more frequently and at higher levels in surface water than Salmonella, but groundwater contamination with any of these organisms was rare, and low levels of resistance can be found sporadically. Resistant bacteria are relatively uncommon in these eastern N.C. surface and groundwaters, but they could pose a risk of human exposure via ingestion or primary contact recreation.

    Full Text Available Dogs and cats play an important role in modern society, enhancing the psychological and physiological well-being of many people. However, there are well-documented health risks associated with human animal interactions. More specifically, enteric pathogens of zoonotic risk which are transmitted by feces of dogs and cats can be grouped as follows: (a Parasites such as Toxocara canis, T. cati, Ancylostoma sp, Uncinaria sp, Strongyloides stercoralis, Echinococcus granulosus, E. multilocularis and Dipylidium caninum (b Protozoa including Toxoplasma gondii, Giardia duodenalis and Cryptosporidium spp. (c Bacteria of the genera Clostridium, Campylobacter, Salmonella, Escherichia, Yersinia and Helicobacter and (d Viruses mainly Rotaviruses and Coronaviruses. Among them, Salmonella, Campylobacter, Rotaviruses, Toxoplasma gondii, Echinococcus have been reported to be of considerable importance for many countries including Greece. Even though official records of the cases in humans and livestock in Greece continuously decline, cystic echinococcosis is considered to be a serious problem for public health and livestock economy. Regarding other parasites, the overall prevalence of parasitism was 26% in owned shepherd and hunting dogs examined in Serres. Furthermore, seroepidemiological studies revealed the presence of antibodies against T. gondii in a considerable percentage of hospitalized children. Rotaviruses were confirmed as a major cause of acute gastroenteritis in children. Finally, bacterial zoonotic enteropathogens were identified in a notable number of pediatric cases. Most of these zoonoses are associated with the exposure of immunodeficient people or children to pets and/or conditions of poor hygiene. Studies on the presence of all these pathogens in animals are required to identify the extent of problem, to define control

  5. African swine fever virus uses macropinocytosis to enter host cells.

    Directory of Open Access Journals (Sweden)

    Elena G Sánchez

    Full Text Available African swine fever (ASF is caused by a large and highly pathogenic DNA virus, African swine fever virus (ASFV, which provokes severe economic losses and expansion threats. Presently, no specific protection or vaccine against ASF is available, despite the high hazard that the continued occurrence of the disease in sub-Saharan Africa, the recent outbreak in the Caucasus in 2007, and the potential dissemination to neighboring countries, represents. Although virus entry is a remarkable target for the development of protection tools, knowledge of the ASFV entry mechanism is still very limited. Whereas early studies have proposed that the virus enters cells through receptor-mediated endocytosis, the specific mechanism used by ASFV remains uncertain. Here we used the ASFV virulent isolate Ba71, adapted to grow in Vero cells (Ba71V, and the virulent strain E70 to demonstrate that entry and internalization of ASFV includes most of the features of macropinocytosis. By a combination of optical and electron microscopy, we show that the virus causes cytoplasm membrane perturbation, blebbing and ruffles. We have also found that internalization of the virions depends on actin reorganization, activity of Na(+/H(+ exchangers, and signaling events typical of the macropinocytic mechanism of endocytosis. The entry of virus into cells appears to directly stimulate dextran uptake, actin polarization and EGFR, PI3K-Akt, Pak1 and Rac1 activation. Inhibition of these key regulators of macropinocytosis, as well as treatment with the drug EIPA, results in a considerable decrease in ASFV entry and infection. In conclusion, this study identifies for the first time the whole pathway for ASFV entry, including the key cellular factors required for the uptake of the virus and the cell signaling involved.

    The effect of ultraviolet (UV) radiation on the devitalization of eight selected enteric viruses suspended in estuarine water was determined. The surviving fractions of each virus were calculated and then plotted against the UV exposure time for purposes of comparison. Analytical assessment of the survival data for each virus consisted of least squares regression analysis for determination of intercepts and slope functions. All data were examined for statistical significance. When the slope function of each virus was compared against the slope function of poliovirus type 1, the analytical findings indicated that poliovirus types 2 and 3, echovirus types 1 and 11, and coxsackievirus A-9 exhibited similar devitalization characteristics in that no statistically significant difference was found (P > 0.05). Conversely, the devitalization characteristics of coxsackievirus B-1 and reovirus type 1 were dissimilar from those of poliovirus type 1 in that a statistically significant difference was found between the slope functions (P < 0.05). This observed difference in devitalization of coxsackievirus B-1 and reovirus type 1 was attributed primarily to the frequency distribution of single and aggregate virions, the geometric configuration, the size of the aggregates, and the severity of aggregation. The devitalization curve of coxsackievirus B-1 was characteristic of a retardant die-away curve. The devitalization curve of reovirus type 1 was characteristic of a multihittype curve. The calculated devitalization half-life values for poliovirus types 1, 2, and 3; echovirus types 1 and 11; coxsackievirus types A-9 and B-1; and reovirus type 1 were 2.8, 3.1, 2.7, 2.8, 3.2, 3.1, 4.0, 4.0 sec, respectively. These basic data should facilitate an operative extrapolation of the findings to the applied situation. It was concluded that UV can be highly effective and provide a reliable safety factor in treating estuarine water.

    Eosinophilic enteritis (EE) in cats is poorly characterized. The aim of the current study was to retrospectively evaluate the clinical and ultrasonographic findings in cats with histologic evidence of eosinophilic inflammation on gastrointestinal biopsy. Twenty-five cats with tissue eosinophilia on surgical (10) or endoscopic (15) biopsy of the gastrointestinal tract, having an abdominal ultrasound performed within 48 h of biopsy acquisition, were enrolled. History, clinical presentation, clinical pathology and abdominal ultrasound findings were reviewed. Intestinal biopsies were evaluated by a single pathologist and separated into two groups based on the degree of eosinophilic infiltrate: mild (eosinophils/high-power field [HPF], 11/25 cats), or moderate/marked (>10 eosinophils/HPF, 14/25 cats). The former were considered primary lymphoplasmacytic or lymphocytic inflammatory bowel disease (LPE) with subtle eosinophilic infiltrates, and the latter to have EE. Signalment, history and clinical signs were similar in all cats. Only cats with EE (6/14) had palpably thickened intestines. The only distinguishing clinicopathological feature of cats with EE was the presence of peripheral eosinophilia (6/14). On ultrasound, when compared with cats with LPE, cats with EE had a greater mean jejunal wall thickness (3.34 mm ± 0.72 mm vs 4.07 mm ± 0.58 mm, respectively) and an increased incidence of thickening of the muscularis layer (1/11 and 11/14, respectively). In conclusion, ultrasonographic evidence of a prominent intestinal muscularis layer, palpably thickened intestines and peripheral eosinophilia can serve as biomarkers for the presence of EE in cats with chronic intestinal signs.

    We review the international recommendations on oral intake of n-3 fatty acids and their content in the enteral nutrition formulas. Their metabolic actions depend on their metabolization to EPA and DHA. The activity of desaturases catalyzing this process increases with exercise, insulin, estrogens in the fertile women, and peroxisomal proliferators, whereas it decreases with fasting, protein and oligoelements deficiencies, age < 30 years, sedentary lifestyle, cigarette smoking, alcohol, cholesterol, trans and saturated fatty acids, insulin deficiency, and stress hormones (adrenalin and glucocorticoids). Most of the guidelines recommend that 20-35% of the total energy comes from fat, being 7-10% saturated fats, 6-10% polyunsaturated, and 20% monounsaturated, in Spain. The recommendation for n-3 FA is 0.5-2 g/day or 0.5-2% of total caloric intake, with an upper limit of 3 g/day. For n-6 FA, 2.5-10% of total caloric intake, the n-6/n-3 ratio not being well established although most of the guidelines recommend 5:1. The EPA and DHA content should be at least 500 mg per day. Finally, the EPA/DHA ratio is 2:1 in most of them. Standard nutrition formulas present an appropriate fat content, although most of the products containing EPA and DHA exceed the limit of 3 g/day. Among the products with hyperprotein and/or concentrated, only of them contains EPA y DHA. Not all the formulas used for the frail elderly contain EPA or DHA, and in those containing them their concentration may be excessive and with a proportion very dissimilar to that of fish oil.

    Full Text Available CONTEXT: HIV is a major global public health issue. Most of the patients with HIV disease die of infections other than HIV. Gastrointestinal infections are very common in patients with HIV infection or AIDS . AIMS : To detect opportunistic intestinal parasi tes in patients living with HIV & AIDS and relate it with CD4 count. SETTINGS AND DESIGN: A single stool sample was obtained in sterile plastic containers from the patients attending pre ART. The stool samples were examined macroscopically and microscopica lly. Formalin ether concentration method was used. The modified Ziehl Neelsen staining method was used for the detection of the oocyst of coccidian parasites. CD4 count was measured on partec flow cytometry. RESULTS: Out of the 53 patient s, 33(62.26% were males and 20 (37.73% were femal es with age between 25 - 65 years . The study population consist of 4 patients with CD4 count > 500 cells/μl , 22 patients with CD4 count 200 - 499 cells/μl and 27 patients with CD4 count < 200 cells/μl.

    Full Text Available Objective: To describe the results of the home enteral nutrition (HEN registry of the NADYA-SENPE group in 2011 and 2012. Material and methods: We retrieved the data of the patients recorded from January 1st 2011 to December 31st 2012. Results: There were 3021 patients in the registry during the period from 29 hospitals, which gives 65.39 per million inhabitants. 97.95% were adults, 51.4% male. Mean age was 67.64 ± 19.1, median age was 72 years for adults and 7 months for children. Median duration with HEN was 351 days and for 97.5% was their first event with HEN. Most patients had HEN because of neurological disease (57.8%. Access route was nasogastric tube for 43.5% and gastrostomy for 33.5%. Most patients had limited activity level and, concerning autonomy, 54.8% needed total help. Nutritional formula was supplied from chemist's office to 73.8% of patients and disposables, when necessary, was supplied from hospitals to 53.8% of patients. HEN was finished for 1,031 patients (34.1% during the period of study, 56.6% due to decease and 22.2% due to recovery of oral intake. Conclusions: Data from NADYA-SENPE registry must be explained cautiously because it is a non-compulsory registry. In spite of the change in the methodology of the registry in 2010, tendencies regarding HEN have been maintained, other than oral route.

    The objective of this study was to evaluate the effect of early enteral nutrition on the incidence of the septic syndrome as well as its tolerance, in patients with severe burns. We retrospectively studied 64 patients older than 15 years of age, with a greater than 20% burned body surface area. They were divided into 2 groups as a function of the time elapsed between the beginning of Enteral Nutrition and the time of the burning: 23 patients were given Enteral Nutrition within 24 hours after the burn, and in 41 patients the enteral nutrition was started later than 24 hours after sustaining the thermal injury. Both groups were similar with respect to age, sex, percentage of 2nd and 3rd degree burns, incidence of inhalation, and deaths. All patients received the Enteral Nutrition through a nasogastric tube, with administration of a polymeric, hyperprotein and hypocaloric formula through a continuous infusion pump. In our study we saw a reduction of the incidence of the septic syndrome in the patients who received early enteral Nutrition (26%; 6 patients of a total of 23), with respect to those who did non receive early Enteral Nutrition (54%; 22 patients of a total of 41), with a statistical significance of p > 0.05. There were no differences between both groups with respect to the digestive tolerance to Enteral Nutrition. From our study we can deduce that early Enteral Nutrition reduces the incidence of septic complications, without this increasing the digestive intolerance to the same.

    Completely isolated enteric duplication cysts are a rare variety of enteric duplication cysts having an independent blood supply with no communication with any part of the adjacent bowel segment. We report a case showing two completely isolated enteric duplication cysts originating in the greater omentum and transverse mesocolon in an infant. Multiple isolated enteric duplication cysts involving non-contiguous bowel segments have not been previously reported in the literature. In addition the transverse mesocolon duplication cyst was infected showing septations and loss of double wall sign resulting in difficulty in imaging diagnosis. Both the cysts were excised and confirmed on histopathology.

    NASA's Exoplanet Exploration Program (ExEP) guides the development of technology that enables the direct imaging and characterization of exo-Earths in the habitable zone of their stars, for future space observatories. Here we present the Starshade portion of the 2017 ExEP Enabling Technology Gap List, an annual update to ExEP's list of of technology to be advanced in the next 1-5 years. A Starshade is an external occulter on an independent spacecraft, allowing a space telescope to achieve exo-Earth imaging contrast requirements by blocking starlight before it enters the telescope. Building and operating a Starshade requires new technology: the occulter is a structure tens of meters in diameter that must be positioned precisely at a distance of tens of thousands of kilometers from the telescope. We review the current state-of-the-art performance and the performance level that must be achieved for a Starshade.

    Full Text Available Background: Malnutrition often occurs in a critical patient caused by various things such as decreasing function of gastrointestinal tract, high process of catabolism and homeostatie destruction. Other problem that may occur when nutrition is given with high total calories could be dangerous because it could cause hiperglikemia, the production improvement of CO blood and worsen the homeostasis destruction. Objective: To find out the difference of PaCO blood in critical patients who obtain commercial enteral food diet or combined enteral food diet. Methods: This was an experimental study using randomized controlled trial with pretest-posttest control group design. The subjects were critical patients who were given care in the intensive installation Dr. Sardjito hospital Yogyakarta who met the criteria: adult patient, using ventilator and receiving enteral food diet. Results: There was no difference between PaCO blood in critical patient who obtained commercial enteral diet and com- bined enteral food diet. There was a change difference of PaCO with 55% compared with <55% from energy total (p=0.03. Conclusion: The improvement of PaCO was not caused by the type of enteral formula given, cause of the high intake of energy and carbohydrate.

  20. Low water FGD technologies

    Conventional flue gas desulphurisation (FGD) systems require large supplies of water. Technologies which reduce water usage are becoming more important with the large number of FGD systems being installed in response to ever tightening emission regulations. Reducing water loss is particularly important in arid regions of the world. This report reviews commercial and near commercial low water FGD processes for coal-fired power plants, including dry, semi-dry and multi-pollutant technologies. Wet scrubbers, the most widely deployed FGD technology, account for around 10–15% of the water losses in power plants with water cooling systems. This figure is considerably higher when dry/air cooling systems are employed. The evaporative water losses can be reduced by some 40–50% when the flue gas is cooled before it enters the wet scrubber, a common practice in Europe and Japan. Technologies are under development to capture over 20% of the water in the flue gas exiting the wet scrubber, enabling the power plant to become a water supplier instead of a consumer. The semi-dry spray dry scrubbers and circulating dry scrubbers consume some 60% less water than conventional wet scrubbers. The commercial dry sorbent injection processes have the lowest water consumption, consuming no water, or a minimal amount if the sorbent needs hydrating or the flue gas is humidified to improve performance. Commercial multi-pollutant systems are available that consume no water.

    Modern risk control and food safety practices involving food-borne bacterial pathogens are benefiting from new genomic technologies for rapid, yet highly specific, strain characterisations. Within the United States Food and Drug Administration (USFDA) Center for Food Safety and Applied Nutrition (CFSAN), optical genome mapping and DNA microarray genotyping have been used for several years to quickly assess genomic architecture and gene content, respectively, for outbreak strain subtyping and to enhance retrospective trace-back analyses. The application and relative utility of each method varies with outbreak scenario and the suspect pathogen, with comparative analytical power enhanced by database scale and depth. Integration of these two technologies allows high-resolution scrutiny of the genomic landscapes of enteric food-borne pathogens with notable examples including Shiga toxin-producing Escherichia coli (STEC) and Salmonella enterica serovars from a variety of food commodities. Moreover, the recent application of whole genome sequencing technologies to food-borne pathogen outbreaks and surveillance has enhanced resolution to the single nucleotide scale. This new wealth of sequence data will support more refined next-generation custom microarray designs, targeted re-sequencing and "genomic signature recognition" approaches involving a combination of genes and single nucleotide polymorphism detection to distil strain-specific fingerprinting to a minimised scale. This paper examines the utility of microarrays and optical mapping in analysing outbreaks, reviews best practices and the limits of these technologies for pathogen differentiation, and it considers future integration with whole genome sequencing efforts.

    1995-01-01

    Jejuno- and ileostomy are common surgical procedures. Due to shortening of effective bowel length intestinal failure, or short bowel syndrome develops. Degree of intestinal failure depends upon 1. resection length, 2. resection location, 3. function of the bowel remnant, stomach, pancreas and liver, 4. adaptive capabilities of the bowel remnant and 5. the disease that was cause of the surgery. In majority of these patients adequate nutrition can be achieved using enteral nutrition. Water and mineral absorption differs between jejunum and ileum. Jejunal mucosa is permeable to sodium and water, causing jejunal content to be isoosmolar to plasma. When sodium concentration in jejunal content is less than 90 mmol/l secretion of sodium into the lumen occurs. Ileal sodium absorption takes place against concentration gradient. Potassium concentration of jejuno- and ileostomy effluent is fairly constant at about 15 mmol/l. Main therapeutic problem is water and mineral loss. In jejunostomy patients hyponatremia is a major concern. Urinary sodium concentration of less than 5 mmol/l is a sign of sodium deficiency. This group of patients should have daily urinary output of more than 800 ml, and urinary sodium concentration of more than 20 mmol/l. Another important problem is malnutrition. Weight changes, albumin and trasferin are important follow-up parameters. Often neglected problem is large stomal effluent volume, that can incapacitate patient for the usual life. All these problems can be prevented by the adequate nutritional support. Oral' fluids should have minimal sodium concentration of 90 mmol/l. Intake of sodium poor fluids should be restricted. If plasma or urinary sodium are low intravenous sodium supplementation is warranted. Magnesium and zinc should be monitored and supplemented. Addition of vitamin D can improve their absorption. Vitamins B12 and K must be given parenteral, because their resorption is severely impaired. Patient should eat usual food rich in

    Objetivos: Describir los resultados del registro de nutrición enteral domiciliaria (NED) del grupo NADYASENPE de los años 2011 y 12. Material y métodos: Se recopilaron los datos introducidos en el registro desde el 1 de enero de 2011 al 31 de diciembre de 2012. Resultados: Hubo 3021 pacientes en el registro durante el periodo, procedentes de 29 hospitales, lo que da una prevalencia de 65,39 casos por millón de habitantes. 97.95% fueron adultos, 51,4% varones. La edad media fue 67,64 ± 19,1 años y la mediana 72 años para los adultos y 7 meses para los niños. La duración media de la NED fue 351 días y para el 97,5% fue el primer episodio con NED. La mayoría de pacientes tenían NED por una enfermedad neurológica (57,8%). La vía de acceso fue sonda nasogástrica para el 43,5% y gastrostomía para el 33,5%. La mayoría de pacientes tuvieron un nivel de actividad física limitado y, respecto a la autonomía, 54,8% necesitaba ayuda total. La fórmula de nutrición se suministró desde las oficinas de farmacia para el 73,8% y los fungibles, cuando fueron necesarios, desde los hospitales para el 53,8%. La NED se suspendió en 1.031 pacientes (34,1%) durante el periodo de estudio, 56,6% debido a fallecimiento y 22,2% debido a recuperación de la vía oral. Conclusiones: Los datos del registro NADYA-SENPE deben ser interpretados con precaución ya que se trata de un registro voluntario. A pesar del cambio de metodología del registro en 2010, las tendencias en NED se han mantenido, salvo la importancia cuantitativa de la vía oral.

    It has been suggested that adding fibre to enteral nutrition (EN) formulas may achieve a normalization of the gastrointestinal tract's functions by reducing the incidence of diarrhoea and constipation. However, this supposition is based on the demonstrated effect of fibre in natural feeding. There have so far been no firm recommendations on the use, amount or type of fibre that is most advisable in EN. To establish the scientific evidence existing on the benefits gained by adding fibre to EN formulas compared with the use of fibre-free formulas. Bibliographical search on PubMed, on the register of Randomized Prospective Trials (RPT) of the Cochrane Library and manual search. RPT comparing fibre-free formulas with isocaloric ad isonitrogen formulas containing fibre in total EN. Four independent reviewers revised the references selected. The data were analyzed using the RevMan 4.1 programme from the Cochrane Library. Of 286 references, 25 fulfilled the inclusion criteria. The data were grouped by population and outcome variable. The addition of fermentable fibre to the EN formulas tends to reduce the incidence of diarrhoea in critically-ill and post-surgery patients (OR = 0.66; 95% CI 0.46-0.95; p = 0.19). The use of formulas with insoluble fibre seems to increase the frequency of depositions and reduce the need for laxatives in immobilized patients receiving long-term EN but the data are insufficient. In people with normal gastrointestinal functions, the frequency of depositions is similar when using formulas with and without fibre (DPM = -0.97; 95% CI -0.12-[-0.02]; p < 0.0001). There is currently insufficient evidence to recommend the systematic use of formulas containing fibre in total EN. However, in critically-ill and post-surgery patients, the use of formulas with fermentable fibre tends to reduce the incidence of diarrhoea. Although information is still lacking. The formulas with insoluble fibre seem to diminish constipation in chronic EN, whereas in other

    Once again, the NADYA-SENPE Working Group analysed the registered data of Home Enteral Nutrition (HEN) in our country, during the year 2000. The data were collected through a closed questionnaire included on our web site (www.nadya-senpe.com). Apart from epidemiological information, the form includes the indication to prescribe this treatment, the specific nutritional treatment used and its duration, access path, complications and readmission rate in hospital, follow-up of the treatment, patient's quality of life and progress. All data were processed and analysed by the co-ordinating team. Twenty two hospital participated and 2,986 patients, aged 65.1 +/- 19.7 years, were enrolled. Of these patients, 41.2% were diagnosed with neurological diseases and 33.3% with cancer. The mean time on HEN was 6.3 +/- 4.4 months. Oral nutrition was the preferential route (50.8%), followed by nasoenteral tube (30.5%), and in 17.4% ostomy tubes were placed. Polymeric was the formula composition mainly used (83.2%). Patients were followed (70.1%) by the hospital reference Nutritional Support Unit. The complications related to nutrition included the gastrointestinal (0.25 complications/patient), the mechanical one (0.19 complications/patient), and the metabolic (0.007 complications/patient). Feeding tube need to be replaced 0.3 times/patient/year. The readmission rate, for nutritional problems, was observed in 0.03 patients. At the end of the year, 54.9% of the patients were in the HEN program, and in 30.3% HEN was finish due to different reasons. In 21.9% of the patients no, o light, discapacity degree was found. Related to previous years, there is an increment in the number of enrolled patients. Neurological diseases and cancer were the more frequent diagnoses in HEN patients. Oral access was the higher feeding route due, probably, to the high prevalence of cancer patients. In spite of the elevated prevalence of neurological diseases, a few number of patients were feed with ostomy

    Full Text Available Abstract Background There is paucity of data on seasonal variation in pulmonary tuberculosis (TB in developing countries contrary to recognized seasonality in the TB notification in western societies. This study examined the seasonal pattern in TB diagnosis among migrant workers from developing countries entering Kuwait. Methods Monthly aggregates of TB diagnosis results for consecutive migrants tested between January I, 1997 and December 31, 2006 were analyzed. We assessed the amplitude (α of the sinusoidal oscillation and the time at which maximum (θ° TB cases were detected using Edwards' test. The adequacy of the hypothesized sinusoidal curve was assessed by χ2 goodness-of-fit test. Results During the 10 year study period, the proportion (per 100,000 of pulmonary TB cases among the migrants was 198 (4608/2328582, (95% confidence interval: 192 – 204. The adjusted mean monthly number of pulmonary TB cases was 384. Based on the observed seasonal pattern in the data, the maximum number of TB cases was expected during the last week of April (θ° = 112°; P α = 0.204 ± 0.04 of simple harmonic curve showed 20.4% difference from the mean to maximum TB cases. The peak to low ratio of adjusted number of TB cases was 1.51 (95% CI: 1.39 – 1.65. The χ2 goodness-of-test revealed that there was no significant (P > 0.1 departure of observed frequencies from the fitted simple harmonic curve. Seasonal component explained 55% of the total variation in the proportions of TB cases (100,000 among the migrants. Conclusion This regularity of peak seasonality in TB case detection may prove useful to institute measures that warrant a better attendance of migrants. Public health authorities may consider re-allocation of resources in the period of peak seasonality to minimize the risk of Mycobacterium tuberculosis infection to close contacts in this and comparable settings in the region having similar influx of immigrants from high TB burden countries

    In the development of advanced technologies, there are several forces which are involved in the success of the development of those technologies. In the overall development of new technologies, a sufficient number of these forces must be present and working in order to have a successful opportunity at developing, introducing and integrating into the marketplace a new technology. This paper discusses some of these forces and how they enter into the equation for success in advanced technology research, development, demonstration, commercialization and deployment. This paper limits itself to programs which are generally governmental funded, which in essence represent most of the technology development efforts that provide defense, energy and environmental technological products. Along with the identification of these forces are some suggestions as to how changes may be brought about to better ensure success in a long term to attempt to minimize time and financial losses.

    Surgical management of children with short bowel syndrome (SBS) changed with the introduction of the serial transverse enteroplasty procedure (STEP). We conducted a systematic review and meta-analysis using MEDLINE and SCOPUS to determine if children with SBS had improved enteral tolerance following STEP. Studies were included if information about a child's pre- and post-STEP enteral tolerance was provided. A random effects meta-analysis provided a summary estimate of the proportion of children with enteral tolerance increase following STEP. From 766 abstracts, seven case series involving 86 children were included. Mean percent tolerance of enteral nutrition improved from 35.1 to 69.5. Sixteen children had no enteral improvement following STEP. A summary estimate showed that 87 % (95 % CI 77-95 %) of children who underwent STEP had an increase in enteral tolerance. Compilation of the literature supports the belief that SBS subjects' enteral tolerance improves following STEP. Enteral nutritional tolerance is a measure of efficacy of STEP and should be presented as a primary or secondary outcome. By standardizing data collection on children undergoing STEP procedure, better determination of nutritional benefit from STEP can be ascertained.

  12. The Use of an Automated System (GreenFeed) to Monitor Enteric Methane and Carbon Dioxide Emissions from Ruminant Animals.

    Ruminant animals (domesticated or wild) emit methane (CH4) through enteric fermentation in their digestive tract and from decomposition of manure during storage. These processes are the major sources of greenhouse gas (GHG) emissions from animal production systems. Techniques for measuring enteric CH4 vary from direct measurements (respiration chambers, which are highly accurate, but with limited applicability) to various indirect methods (sniffers, laser technology, which are practical, but with variable accuracy). The sulfur hexafluoride (SF6) tracer gas method is commonly used to measure enteric CH4 production by animal scientists and more recently, application of an Automated Head-Chamber System (AHCS) (GreenFeed, C-Lock, Inc., Rapid City, SD), which is the focus of this experiment, has been growing. AHCS is an automated system to monitor CH4 and carbon dioxide (CO2) mass fluxes from the breath of ruminant animals. In a typical AHCS operation, small quantities of baiting feed are dispensed to individual animals to lure them to AHCS multiple times daily. As the animal visits AHCS, a fan system pulls air past the animal's muzzle into an intake manifold, and through an air collection pipe where continuous airflow rates are measured. A sub-sample of air is pumped out of the pipe into non-dispersive infra-red sensors for continuous measurement of CH4 and CO2 concentrations. Field comparisons of AHCS to respiration chambers or SF6 have demonstrated that AHCS produces repeatable and accurate CH4 emission results, provided that animal visits to AHCS are sufficient so emission estimates are representative of the diurnal rhythm of rumen gas production. Here, we demonstrate the use of AHCS to measure CO2 and CH4 fluxes from dairy cows given a control diet or a diet supplemented with technical-grade cashew nut shell liquid.

  13. Preparation and in vitro/in vivo characterization of enteric-coated nanoparticles loaded with the antihypertensive peptide VLPVPR

    Full Text Available Haiyan Sun, Dong Liu, Yan Li, Xuwei Tang, Yanli Cong Shenzhen Key Laboratory of Fermentation, Purification and Analysis, Shenzhen Polytechnic, Guangdong, People's Republic of China Abstract: Our previous study revealed that the peptide Val-Leu-Pro-Val-Pro-Arg (VLPVPR, which was prepared using deoxyribonucleic acid recombinant technology, effectively decreased the blood pressure of spontaneous hypertensive rats; however, the effect only lasts 6 hours, likely due to its low absorption in the gastrointestinal tract. To overcome this problem, the purpose of this study was to characterize (methoxy-polyethylene glycol-b-poly(D,L-lactide-co-glycolide-b-poly(L-lysine nanoparticles as in vitro and in vivo carriers for the effective delivery of VLPVPR. In our study, the VLPVPR nanoparticles were prepared using a double emulsion method, coated with Eudragit S100, and freeze-dried to produce enteric-coated nanoparticles. The optimized parameters from the double emulsion method was obtained from orthogonal experiments, including drug loading (DL and encapsulated ratio (ER at 6.12% and 86.94%, respectively, and the average particle size was below 100 nm. The release experiment demonstrated that the nanoparticles were sensitive to pH: almost completely released at pH 7.4 after 8 hours, but demonstrated much less release at pH 4.5 or pH 1.0 in the same amount of time. Therefore, the nanoparticles are suitable for enteric release. In vivo compared with the untreated group, the medium and high doses of orally administered VLPVPR nanoparticles reduced blood pressure for more than 30 hours, demonstrating that these nanoparticles have long-lasting and significant antihypertensive effects in spontaneously hypertensive rats.

    Early pathological manifestations of Crohn's disease (CD) include vascular disruption, T cell infiltration of nerve plexi, neuronal degeneration, and induction of T helper 1 cytokine responses. This study demonstrates that disruption of the enteric glial cell network in CD patients represents another early pathological feature that may be modeled after CD8+ T cell-mediated autoimmune targeting of enteric glia in double transgenic mice. Mice expressing a viral neoself antigen in astrocytes and enteric glia were crossed with specific T cell receptor transgenic mice, resulting in apoptotic depletion of enteric glia to levels comparable in CD patients. Intestinal and mesenteric T cell infiltration, vasculitis, T helper 1 cytokine production, and fulminant bowel inflammation were characteristic hallmarks of disease progression. Immune-mediated damage to enteric glia therefore may participate in the initiation and/or the progression of human inflammatory bowel disease.

    AIM: To establish the role of enteric glial cells duringinfection with Mycobacterium avium subspeciesparatuberculosis (MAP) in Crohn's disease.METHODS: In order to establish the role of enteric glial cells during infection with M. avium subspecies paratuberculosis (MAP) in Crohn's disease, Map adhesion experiments on enteric glial cells were performed as well as expression analysis of Map sigma factors during infection.RESULTS: In this study, for the first time, we found a high affinity of MAP to enteric glial cells and we analyzed the expression of MAP sigma factors under different conditions of growth.CONCLUSION: The fact that Map showed a high affinity to the glial cells raises concerns about the complicated etiology of the Crohn's disease. Elucidation of the mechanisms whereby inflammation alters enteric neural control of gut functions may lead to novel treatments for Crohn's disease.

    Cytomegalovirus (CMV) enteritis (or colitis) is generally diagnosed in immunocompromised patients in association with human immunodeficiency virus infection as well as in recipients of solid organ or hematopoietic stem cell transplant. CMV enteritis has been reported only sporadically in immunocompetent individuals. We encountered a 76-year-old woman who developed CMV enteritis without any previously identified immunocompromised states. An extensive literature review of 33 cases of CMV enteritis or colitis diagnosed in immunocompetent individuals, including the present case, revealed that the median age of the patients was 68, the accompanying symptoms were diarrhea (76%), abdominal pain (52%), and hematochezia or melena (27%), and that the outcome was generally favorable, including resolution without any treatment in 24% of the patients. CMV enteritis should be recognized more widely as a disease entity not only in immunocompromised patients but also in immunocompetent individuals, especially in elderly populations.

    2008-03-01

    An ovitrap with a time-segregated entrance was used to separate eggs laid by Aedes sierrensis females according to the time of day that females entered the ovitrap. During a 37-day period in Lake County, CA, females that entered the ovitrap between sunrise and sunset laid 82% of the total number of eggs collected. A daily peak in oviposition (eggs per hour) was produced by females that entered during the 2-h period ending at sunset. Overall, females that oviposited had entered the ovitrap throughout the diel cycle except for a 2-h period ending at sunrise. Those eggs laid by females that entered the ovitrap between 2 h after sunset and 2 h before sunrise provided the 1st evidence that Ae. sierrensis females are capable of locating oviposition sites during the night.

  18. Hot-melt sub- and outercoating combined with enteric aqueous coating to improve the stability of aspirin tablets

    2017-05-01

    Full Text Available Aspirin is apt to hydrolyze. In order to improve its stability, a new method has been developed involving the application of hot-melt sub- and outercoating combined with enteric aqueous coating. The main aim was to investigate the influence of these factors on the stability of ASA and understand how they work. Satisfactory storage stability were obtained when the aspirin tablet core coated with Eudragit L30D55 film was combined with glycerin monostearate (GMS as an outercoat. Hygroscopicity testing indicated that the moisture penetrating into the tablet may result in a significant change in the physical properties of the coating film observed by scanning electron microscopy. Investigation of the compatibility between the drug and film excipients shows that the talc and methacrylic acid had a significant catalytic effect on ASA. A hypothesis was proposed that the hydrolysis of ASA enteric coated tablets (ASA-ECT was mostly concentrated in the internal film and the interfaces between the film and tablet core. In conclusion, hot-melt coating technology is an alternative to subcoating or outercoating. Also, GMS sub-coating was a better choice for forming a stable barrier between the tablet core and the polymer coating layer, and increases the structure and chemical stability.

    2014-08-01

    Astyanax mexicanus, a teleost fish comprising both sighted river-dwelling and blind cave-dwelling morphs, is becoming increasingly used in the field of developmental and evolutionary biology. Thus, new experimental and technological tools are needed on this emerging fish model by the expanding scientific community. Here, we describe Astyanax husbandry and egg spawning habits, a prerequisite to the successful establishment of Astyanax transgenic lines. We then compare two different transgenesis methods on both surface and cave Astyanax. Both meganuclease (I-SceI)- and transposase (Tol2)-mediated transgenesis are equivalently efficient, resulting in ∼40% mosaic transgenic fish in F0. Furthermore, the transmission rate was analyzed in F1 in the case of the I-SceI method and was found to be 16%. Finally, the transgene was found stable up the F3 generation, demonstrating the feasibility of generating stable transgenic lines in Astyanax and opening a wide range of possibilities for this fish model.
